Detailed Description

The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.

In the present invention, unless otherwise expressly stated or limited, "above" or "below" a first feature means that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact with each other via another feature therebetween. Also, the word "over" a first feature or feature in a second feature may include the word "over" or "over" the second feature, or may simply indicate that the first feature is at a higher level than the second feature. A first feature "under" a second feature may include a first feature that is directly under and obliquely under the second feature, or may simply mean that the first feature is at a lesser elevation than the second feature.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

As shown in fig. 1, the air switch isolation device of the present embodiment includes an isolation cover 1, a first fixing member 2 and a second fixing member 3, the first fixing member 2 and the second fixing member 3 are respectively disposed on the top surface of the air switch casing 100 and the bottom surface of the air switch casing 100, and both ends of the isolation cover 1 are respectively connected to the first fixing member 2 and the second fixing member 3, so that the isolation cover 1 isolates the air switch handle 200.

The air switch isolating device of this embodiment sets up first mounting 2 and second mounting 3 on air switch shell 100, for cage 1 provides the mounted position, makes cage 1 keep apart air switch handle 200, effectively prevents that personnel from missing to touch air switch handle 200, simple structure and with low costs.

As shown in fig. 2 and 3, preferably, the insulation cover 1 includes a cover body 11, a first connecting portion 12 and a second connecting portion 13, the first connecting portion 12 and the second connecting portion 13 are respectively disposed at two ends of the cover body 11, the first connecting portion 12 is selectively connected to the first fixing member 2, and the second connecting portion 13 is hinged to the second fixing member 3. Therefore, the isolation cover 1 can be rotated to realize the switching of the isolated or non-isolated state of the air switch handle 200, when the isolation of the air switch handle 200 is not needed, the isolation cover 1 still keeps the connection with the second fixing piece 3, the arrangement of a placing place for the isolation cover 1 is not needed, and the loss of the isolation cover 1 can be prevented.

Furthermore, the end face of the opening side of the cover body 11 can be attached to the surface of the air switch casing 100, so that the cover body 11 can realize omnibearing sealing and isolation on the air switch casing 100, the air switch handle 200 cannot be operated from any angle, and the safety is improved.

Further, the first fixing member 2 and the second fixing member 3 are bonded to the air switch case 100. Therefore, the air switch isolating device can be installed on the premise of not changing the overall structure of the air switch, and the air switch isolating device is high in practicability and safety.

Specifically, the first fixing member 2 includes a first horizontal segment 21 and a first vertical segment 22 that are connected perpendicularly to each other, the first horizontal segment 21 is adhered to the top surface of the air switch casing 100, the first vertical segment 22 is selectively connected to the first connecting portion 12, the second connecting portion 13 includes a first hinge lug 131, the second fixing member 3 includes a second horizontal segment 31, a second vertical segment 32 and a second hinge lug 33, the second horizontal segment 31 is perpendicularly connected to the second vertical segment 32, the second hinge lug 33 is disposed at one end of the second vertical segment 32 away from the second horizontal segment 31, and the first hinge lug 131 is hinged to the second hinge lug 33. The first horizontal section 21 and the second horizontal section 31 have a larger contact area with the air switch casing 100, so that the first fixing piece 2 and the second fixing piece 3 can be firmly fixed on the air switch casing 100, the first vertical section 22 provides a sufficient connection position for the first connection portion 12, and the connection reliability is ensured, and the first hinge lug 131 and the second hinge lug 33 are used for realizing the hinge connection of the isolation hood 1 and the second fixing piece 3.

Further, the first vertical section 22 and the first connecting portion 12 are both provided with through holes (not shown in the figure), and the first vertical section 22 and the first connecting portion 12 are connected by the lock 4. Through setting up tool to lock 4, can prevent that personnel from opening cage 1 at will and operating air switch handle 200, improve the security.

Specifically, the lock 4 is a five-prevention lock. Five prevent locks are a power equipment lock, wherein five prevent specifically including: the switch is prevented from being pulled and closed by mistake; the isolation switch is prevented from being pulled and closed under load; prevent the false entering into the electrified interval; the earth wire is prevented from being hung in a charged state; the switch-on of the grounding knife switch is prevented. When the personnel operate the five-prevention lock, the electrical equipment needs to be correctly operated according to a set safe operation program so as to avoid the occurrence of misoperation accidents.

Preferably, the isolation cover 1 is made of transparent plastic, and even after the isolation cover 1 is connected with the first fixing part 2, a person can still observe the state of the air switch handle 200, so that the real-time confirmation of the state of the air switch is realized. In addition, the isolation cover 1 made of plastic has light weight, so that the requirements on the strength of the first fixing piece 2 and the second fixing piece 3 are low, and the load carried by the air switch shell 100 is also low.

In some embodiments, the first fixing member 2 and the second fixing member 3 are fixed to the air switch case 100 by screws (not shown). The mode of adhesive connection is very convenient and can not cause structural change to air switch shell 100, but has the possibility that the bonding department is ageing, pine takes off after long-time the use, and the mode of adopting the screw fixation then has higher reliability and steadiness.

Further, the screw is made of insulating materials, and because the screw needs to be driven into the air switch shell 100, the screw made of the insulating materials can prevent the screw from having adverse effects on the internal structure of the air switch and can also prevent the screw from being accidentally electrified to have adverse effects on the safety of personnel.
