Technical field

The present invention relates to breaker protective case technical field, specially a kind of novel vacuum circuit breaker insulating sheath.

Background technique

Vacuum circuit breaker can realize high current by the excellent insulation performance and interrupting performance in high vacuum Partition, in order to improve the security performance of vacuum circuit breaker, can generally be arranged insulating sheath, insulating sheath is on vacuum circuit breaker The sharp weapon of distribution insulating and power supply reliability are improved, it can effectively prevent exposed power equipment electrical connector due to (artificial Touch, toy or sundries overlap joint, acid rain and chemical atmospheres corrosion) caused by power failure and electric shock accidents, as distribution is entirely exhausted Edge degree constantly improve, and puts forward higher requirements to the reasonable structure of insulating sheath product, configuration type selecting adaptability.

In order to enable insulating sheath use of time enhanced convenience, insulating sheath by previous whole shell become Demountable two shells pass through snapping or are bolted before latter two right shell, dismounting when easy access, again It is multiple to use, but the leakproofness for allowing for entire insulation crust in this way is not strong, leads to a large amount of steam and ash in outside air Dirt etc. can enter the inside of insulating sheath, so that some unfavorable shadows still can be caused to the joint of vacuum circuit breaker It rings, shortens the service life of vacuum circuit breaker.

Summary of the invention

(1) the technical issues of solving

In view of the deficiencies of the prior art, it the present invention provides a kind of novel vacuum circuit breaker insulating sheath, solves entire The leakproofness of insulation crust is not strong, causes a large amount of steam and dust etc. in outside air that can enter the interior of insulating sheath Portion shortens vacuum circuit breaker and uses the longevity so that still some detrimental effects can be caused to the joint of vacuum circuit breaker The problem of life.

(2) technical solution

In order to achieve the above object, the present invention is achieved by the following technical programs: a kind of novel vacuum circuit breaker insulation Sheath, including rear end insulating sheath are fixedly connected with front end insulating sheath on the left of the rear end insulating sheath, and the front end is exhausted Conducting wire fixation kit is provided on the left of edge sheath, the bottom thread of the rear end insulating sheath is connected with insulating sheath and fixes Seat, the threaded upper ends of the insulating sheath fixing seat are connected with protective nut.

Preferably, the rear end insulating sheath is made of the first rear end sheath shell and the second rear end sheath shell, described First rear end sheath shell is flexibly connected with the second rear end sheath shell by connects hinge, first rear end sheath shell with The screw top of insulating sheath fixing seat connects, and first rear end sheath shell and the side wall of the second rear end sheath shell are solid Surely restraining position ring block is connected, and the inside of the first rear end sheath shell and the second rear end sheath shell forms an arc-shaped cavity.

Preferably, the front end insulating sheath is made of the first front end sheath shell and the second front end sheath shell, and the The inside of one front end sheath shell and the second front end sheath shell forms a straight line cavity, first front end sheath shell Upper and lower surface is fixedly installed with the first link block, and the upper and lower surface of second front end sheath shell is fixedly installed with second The inside of link block, first link block and the second link block offers identical threaded hole.

Preferably, the conducting wire fixation kit includes socket plectane, is fixedly connected on the right side of the socket plectane several A grafting block, and jack compatible with grafting block is offered on the left side wall of front end insulating sheath, it is described to be socketed the upper of plectane Lower both ends are fixedly installed with fixed block, offer circular hole on the side wall of the socket plectane, and the inside of circular hole is fixedly mounted There is rubber washer.

Preferably, the inside of first rear end sheath shell and the first front end sheath shell is fixedly installed with rubber strip card The inside of item, second rear end sheath shell and the second front end sheath shell is fixedly installed with sealing rubber strip, the rubber Strip is mutually clamped with sealing rubber strip.

Preferably, it is made of the raw material of following weight proportion: 60-80 parts of phenol-formaldehyde resin powder, 10-15 parts of stabilizer, plasticising 7-9 parts of agent, 2-4 parts of antioxidant, 3-5 parts of fire retardant, 1-2 parts of additive, the additive are nano aluminium oxide.

Working principle: in use, the bolt of connection the first link block and the second link block is first removed, thus i.e. openable the One rear end sheath shell and the second rear end sheath shell, since the first rear end sheath shell and the second rear end sheath shell pass through company Articulate connection is connect, so the first rear end sheath shell may be rotated with the second rear end sheath shell, then by vacuum Conducting wire at circuit breaker connector enters from the bottom of insulating sheath fixing seat, and conducting wire is protected by rear end insulating sheath and front end insulation Cavity inside set, then comes out from the left end of front end insulating sheath, then wire head is passed through the rubber of socket plectane side wall installation In the circular hole of rubber gasket, then the grafting block for being socketed plectane right end is inserted on the left side wall of front end insulating sheath again, then First rear end sheath shell is closed up with the second rear end sheath shell, so that rubber strip strip gets up with sealing rubber strip clamping, together When the first link block and the second link block are bolted, then protective nut is rotated, so that the top of protective nut It fits with the bottom of stop collar, finally insulating sheath fixing seat is mounted on the top of vacuum separator.

(3) beneficial effect

The present invention provides a kind of novel vacuum circuit breaker insulating sheaths.Have it is following the utility model has the advantages that

It is 1, of the invention by installing rubber strip strip in the inside of the first rear end sheath shell and the first front end sheath shell, Sealing rubber strip is installed in the inside of the second rear end sheath shell and the second front end sheath shell, and insulating sheath group install with Rubber strip strip is mutually clamped with sealing rubber strip afterwards, so that the junction between insulating sheath shell has good leakproofness, The steam and dust in outside air can be effectively prevented, protects and is not interfered at circuit breaker connector, it can be effective The service life for extending vacuum circuit breaker.

2, the first rear end sheath shell is connect by the present invention by connects hinge with the second rear end sheath shell, is connected by first The first front end sheath shell and the second front end sheath shell can be connected by connecing block and the second link block, and connection type is simple It is practical, complicated connection type is avoided, so that insulating sheath is very convenient when disassembly.

3, the present invention can be greatly reduced the opening on the left of the insulating sheath of front end, be subtracted by the conducting wire fixation kit of setting The entrance of few air, while the circular hole that the rubber washer being arranged can make conducting wire fixation kit open up can be adapted for difference greatly Small conducting wire.

4, the present invention in the making material of insulating sheath by being added additive nano aluminium oxide, so that insulating sheath has There is the function of antistatic, can effectively avoid electrostatic to the disturbed condition of vacuum circuit breaker joint.
