The embodiment of the application discloses a novel low-voltage cabinet improvement method.

Referring to fig. 1, fig. 2 and fig. 5, an embodiment of a novel low voltage cabinet improvement method provided in an embodiment of the present application includes:

s1, the electricity meter in the reserved metering chamber 10 is moved to the adjacent compartment 50, and the adjacent compartment 50 forms the electricity meter chamber 51. Specifically, the large-volume meter in the reserved metering room 10 of the access line cabinet 100 shown in fig. 5 is moved to the adjacent compartment 50, so that the adjacent compartment 50 forms the meter room 51 shown in fig. 2.

S2, the reserved measuring chamber 10 is set as the secondary cell chamber 11, and the mounting position of the frame switch 60 is moved up by a first preset distance. Specifically, the reserved metering chamber 10 after emptying is improved into a secondary element chamber 11 as shown in fig. 2, the problem that the existing fixed low-voltage switch cabinet 100 does not have an independent secondary element chamber 11 is solved, compression of the reserved metering chamber 10 is mainly realized, and therefore more longitudinal spaces are vacated to move the frame switch 60 in the installation position by a first preset distance, the arrangement height of the incoming line copper bar 80 is improved, and installation and arrangement of cables are facilitated.

And S3, horizontally arranging the horizontal busbar 20, and moving the installation position of the outgoing line molded case switch 70 upwards by a second preset distance. Specifically, the vertical arrangement mode of the horizontal busbar 20 in fig. 5 is improved to the horizontal arrangement mode shown in fig. 2, the occupation of the horizontal busbar 20 in the longitudinal space can be reduced, more longitudinal spaces can be vacated, so that the second preset distance can be conveniently moved up from the installation position of the molded case switch, the installation height of the molded case switch is improved, and the installation of the outgoing cables is facilitated.

S4, arranging the N rows 30 on the area behind the outlet molded case switch 70. Specifically, the arrangement of the N rows 30 in the front of the cabinet in fig. 5 is changed into the arrangement in the cabinet as shown in fig. 2, and the N rows 30 are arranged in the area behind the outgoing molded case switch 70, so that the problem of blocking interference on the installation of outgoing cables when the N rows 30 are arranged in the front of the cabinet in the past is solved, and the installation convenience of the outgoing cables is further improved.

Through above-mentioned improvement scheme, solved present fixed low-voltage switchgear cable installation degree of difficulty greatly, the inconvenient problem of construction betterly.

The above is a first embodiment of a novel method for improving a low voltage cabinet provided by the embodiment of the present application, and the following is a second embodiment of the novel method for improving a low voltage cabinet provided by the embodiment of the present application, please refer to fig. 2 to 7 specifically.

The scheme based on the first embodiment is as follows:

further, the method also comprises the improvement steps of:

the incoming copper bar 80 is extended downward to the lower side of the outgoing molded case switch 70. Specifically, as shown in fig. 5, the conventional incoming line copper bar 80 is blocked by the mounting plate 40 of the outgoing line molded case switch 70 in the installation arrangement, which increases the installation difficulty of the incoming line cable. Therefore, the incoming line copper bar 80 is extended downwards to a position where the incoming line copper bar is not blocked by the outgoing line molded case switch 70 or the mounting plate 40 of the outgoing line molded case switch 70, so that the mounting convenience of the incoming line cable is further improved.

Further, the method also comprises the improvement steps of: when the access cabinet 100 is matched with the contact cabinet 200, the cable usage between the access cabinet 100 and the contact cabinet 200 is reduced;

the access cabinet 100 and the contact cabinet 200 are connected by copper bars. The reliability of one-time connection is improved, and the construction difficulty is reduced.

Further, the method also comprises the improvement steps of: take the incoming and outgoing line cabinet 100 with the contact cabinet 200 as an example:

the horizontal busbar 20 on the incoming and outgoing line cabinet 100 still has the generator interface 91, and the generator interface 91 is disposed on the horizontal busbar 20, which may also increase the difficulty in installing the cable of the generator interface 91 to some extent. For this reason, the generator interface 91 is moved into the contact cabinet 200, thereby facilitating the installation of the generator interface 91 cable. The generator interface 91 may be a generator lug or a standard socket, without limitation.

Further, the method also comprises the improvement steps of: as shown in fig. 4, taking a single in-out cabinet 100 application as an example:

the problem that installation of a generator interface 91 cable and a communication interface 92 cable is difficult due to the fact that the generator interface 91 and the communication interface 92 are arranged on the horizontal busbar 20 in the prior art is solved. The generator interface 91 and the contact interface 92 are together transferred to the area behind the electricity meter room 51, and the generator interface 91 and the contact interface 92 may be specifically arranged right behind the electricity meter room 51, without limitation.

Further, the first predetermined distance may be 150mm, and the second predetermined distance is 300 mm. Therefore, the height of the incoming cable interface of the incoming copper bar 80 reaches 450mm, the height of the outgoing cable interface of the outgoing molded case switch 70 reaches 530mm, the situations that the incoming cable interface in the existing incoming and outgoing cabinet 100 is blocked and the height of the outgoing cable interface of the outgoing molded case switch 70 is only 230mm are greatly improved, the installation convenience of the incoming cable and the outgoing cable is improved, and certainly, the first preset distance and the second preset distance can be adjusted according to actual design requirements and are not limited.

Further, the method also comprises the improvement steps of: when the outgoing-line molded-case switches 70 on the incoming-outgoing line cabinet 100 are more in number and unnecessary, the unnecessary outgoing-line molded-case switches 70 can be removed from the situation that more installation positions are reserved for the generator interface 91 and the contact interface 92, and the generator interface 91 and the contact interface 92 can be arranged on the area behind the electric meter room 51 near the outgoing-line molded-case switches as shown in fig. 4.

Taking the improvement of the 800kVA in-out cabinet 100 as an example, two 250A outgoing molded case switches 70 are not used for a long time, so that the two 250A outgoing molded case switches 70 can be removed, that is, the one-in-six-out configuration shown in fig. 6 is improved to the one-in-four-out configuration shown in fig. 7.

As shown in fig. 2 to 4, the present application further discloses a novel low-voltage cabinet, which is improved by the improved method applied to the first embodiment, and comprises an incoming and outgoing line cabinet 100;

a secondary element chamber 11 and an ammeter chamber 51 which are arranged adjacent to each other are provided at an upper position in the inlet/outlet cabinet 100; the horizontal busbar 20 in the incoming and outgoing line cabinet 100 is horizontally arranged; the in-out cabinet 100 is provided with N rows 30 located in the area behind the outgoing molded case switch 70, that is, the N rows 30 arranged in front of the existing cabinet are arranged in the cabinet, and are specifically arranged in the area behind the outgoing molded case switch 70.

Further, the incoming copper bar 80 in the incoming and outgoing cabinet 100 extends downward to below the outgoing molded case switch 70.

Further, for the application of the single inlet/outlet cabinet 100, the generator interface 91 and the communication interface 92 of the inlet/outlet cabinet 100 are disposed together in the area behind the electric meter room 51.

While the present invention has been described with reference to the drawings, it is to be understood that the same is by way of illustration and example only and is not to be taken by way of limitation, and that the scope of the invention is not limited to the details of the embodiments and examples shown.
