Abstract

A kind of transformer station's handcart-type switch experiment lead wire, including a cable in stock lead wire and movable chain, the cable in stock lead wire includes public plug affixed successively, cable and female, the public plug is used for the female connection with the secondary line in handcart room, the female is used for the public plug connection with the secondary line in switch cubicle, the movable chain includes chain joint affixed successively, chain and latch hook, the chain joint passes through the hole of the lock board on switch cubicle front cabinet door from inner side, and pin chain joint with padlock, so as to fixed chain joint, the latch hook is buckled on the bolt staple of switch cabinet body side.The potential safety hazard brought when the utility model is compared to traditional wheelbarrow switch transmission test, comply fully with the regulation of related code, solve the problem of wheelbarrow switch carries out transmission test under inspecting state well, the electrical connection of wheelbarrow switch and switch cubicle interior power when realizing transmission test, both the safety of the person and equipment had been can ensure that, also smoothly completing for transmission test is can guarantee that, and it is simple in construction, it is easy to operate.

Description

A kind of transformer station's handcart-type switch experiment lead wire
Technical field
The utility model is related to transmission & distribution switch cabinet field, and in particular to a kind of experiment of transformer station's handcart-type switch is connect with drawing Line.
Background technology
With the development of national economy, the continuous progress of technology, high-and low-voltage switch equipment is due to its miniaturization, high usability The small advantage in face, can be taken up an area, the application in fields such as generating, transmission of electricity, power transformation production scene and communal facility residents is increasingly extensive. Set type switch cubicle is strayed into maintenance cabinet while running work to us and bringing convenience, there is also maintainer and touches powered set For the phenomenon for causing personnel's electric shock casualty accident.
The high-voltage complete-set switch cabinet of current domestic production, when wheelbarrow switch is in inspecting state, wheelbarrow switch must be in cabinet Outside body, before and after switch cabinet door must close and lock (according to《Anhui power system schedule regulation》With《National grid power ampere Full working regulation》Regulation).When needing to carry out overall transmission test after the completion of wheelbarrow switch maintenance, it may appear that at wheelbarrow switch In outside switch cabinet body, there are the feelings of a certain distance between the wiring of wheelbarrow switch secondary cable and switch cabinet body fixed socket Condition, transmission test contradiction can not be carried out by producing wheelbarrow switch, if carrying out transmission test, must be opened cabinet door, by hand Stopping switch overhauls position outside cabinet and is pushed into testing position in switch cubicle, and wheelbarrow switch secondary cable can be connected to progress whole group biography Dynamic test.This is just violated《Anhui power system schedule regulation》The 4-8 articles equipment state, which changes, scheduled must agree to and criticize It is accurate and《National grid electric power safety working regulation》3.3.2, operations staff must not change equipment running status without authorization.
Utility model content
In view of the above-mentioned problems, a kind of transformer station's handcart-type switch experiment lead wire of the utility model offer is above-mentioned to solve Shortcoming and problem.
The purpose of this utility model is realized using following technical scheme:
A kind of transformer station's handcart-type switch experiment lead wire, including a cable in stock lead wire and movable chain, institute Stating cable in stock lead wire includes affixed public plug, cable and female successively, the public plug be used for and handcart room in The female connection of secondary line, the female is used for the public plug connection with secondary line in switch cubicle, the movable chain bag Chain joint affixed successively, chain and latch hook are included, the chain joint passes through the lock board on switch cubicle front cabinet door from inner side Hole, and chain joint is pinned with padlock, so that fixed chain joint, the latch hook is buckled in the bolt staple of switch cabinet body side On.
Preferably, the public plug of the cable in stock lead wire is contact pin type structure, and female is jack type structure.
Preferably, the length of the chain ensure that switch cubicle has enough apertures to draw cable in stock lead wire.
The beneficial effects of the utility model are:The potential safety hazard brought during compared to traditional wheelbarrow switch transmission test, The experiment complies fully with the regulation of related code with lead wire, wheelbarrow switch and switch cubicle interior power when realizing transmission test Electrical connection, both can ensure that the safety of the person and equipment, and also can guarantee that smoothly completing for transmission test, and simple in construction, easily In operation.
Brief description of the drawings
Using accompanying drawing, the utility model is described in further detail, but the embodiment in accompanying drawing is not constituted to of the present utility model Any limitation, on the premise of not paying creative work, can also be according to following attached for one of ordinary skill in the art Figure obtains other accompanying drawings.
Fig. 1 is the connection front elevation of experiment lead wire;
Fig. 2 is cable in stock lead wire plan;
Fig. 3 is movable chain plan.
Reference:
Public plug 1, female 2, cable 3, chain joint 4, chain 5, latch hook 6.
Embodiment
The utility model is further described with the following Examples.
Referring to Fig. 1, Fig. 2 and Fig. 3, a kind of transformer station's handcart-type switch experiment lead wire of the present embodiment, including one Cable in stock lead wire and movable chain, the cable in stock lead wire include public plug, cable and female plug affixed successively Head, wheelbarrow switch is when carrying out drive experiments after the completion of maintenance, the public plug is used for the female with secondary line in handcart room Connection, the female is used for the public plug connection with secondary line in switch cubicle, it is ensured that Switch main body and switch cubicle interior power Electrical connection, in addition, the length of cable is selected according to supporting switch cubicle size, the male plug of the cable in stock lead wire Head is contact pin type structure, and female is jack type structure;The movable chain includes chain joint, chain and lock affixed successively Hook, when doing transmission test, in order to ensure that switch cubicle keeps certain aperture, the chain joint is passed through before switch cubicle from inner side The hole of lock board in cabinet door, and chain joint is pinned with padlock, so that fixed chain joint, the latch hook is buckled in switch cabinet body On the bolt staple of side, the length of the chain ensure that switch cubicle has enough apertures to draw cable in stock lead wire.
Finally it should be noted that above example is only illustrating the technical solution of the utility model, rather than to this reality With the limitation of novel protected scope, although being explained with reference to preferred embodiment to the utility model, this area it is general Lead to it will be appreciated by the skilled person that can be modified to the technical solution of the utility model or equivalent substitution, without departing from reality With the spirit and scope of new technique scheme.
