Abstract
The utility model relates to the field of power supply equipment maintenance and especially relates to a safety extending device used for aviation plugs for secondary maintenance of a high-voltage switch cabinet. The device includes a testing cart (2). An insulation barrier board (1) is fixed on an end of the testing cart (2). A barrier board opening valve (3) is arranged in the middle of the insulation barrier board (1). A secondary extending line (4) is arranged in the barrier board opening valve (3). Two ends of the secondary extending line (4) are connected with the aviation plugs (5). According to the utility model, a completely-enclosed safety operation environment of electrified equipment is formed only by opening the barrier board opening valve, inserting the aviation plugs and isolating an electrified zone through the insulation barrier board. Personnel security is guaranteed fully. At the same time, an instrument receiving groove is arranged for holding testing instruments, so that efficiency of testing work is improved.
Description
Technical field
The utility model relates to a kind of power supply unit maintenance field, particularly a kind of high-tension switch cabinet secondary maintenance aviation plug safety extension device.
Background technology
Electric power system partly has a power failure while overhauling in transformer station; can run into switch and be hauled out that cabinet is outer can not carry out the situation of transmission test in cabinet; now need to connect protective device and a switch with secondary maintenance aviation plug security lengthening line, at cabinet, carry out protection switch transmission test outward.At present owing to lacking the secondary maintenance aviation plug safety extension device of high-tension switch cabinet special use; during test, protective debugging personnel and charging equipment hypotelorism and primary equipment are in open mode;, there is certain potential safety hazard in the safety measures such as naked baffle plate.Existing secondary line is too short simultaneously, also inconvenient aviation plug access.Therefore, be to guarantee the safe distance of overhaul efficiency and operating personnel and equipment live part, designing a kind of secondary that is applied to high-tension switch cabinet, to overhaul aviation plug safety extension device very necessary.
Utility model content
According to above deficiency of the prior art, problem to be solved in the utility model is: a kind of saving human cost and time cost are provided, improve overhaul efficiency, mobile flexible high-tension switch cabinet secondary maintenance aviation plug safety extension device.
The utility model solves the technical scheme that its technical problem adopts:
Described high-tension switch cabinet secondary maintenance aviation plug safety extension device, comprise test cart, one end fixed insulation baffle plate of test cart, arranges baffle plate and opens valve in the middle of insulation barrier, baffle plate is opened in valve secondary extension cord is set, and secondary extension cord two ends connect aviation plug.
Described high-tension switch cabinet secondary maintenance aviation plug safety extension device is used insulation barrier and the comprehensive insulation of primary equipment, reliable and secure, avoids maintainer directly to contact with live part.The central authorities of insulation barrier are provided with baffle plate and open valve simultaneously, can open baffle plate unlatching valve aviation plug is inserted on cabinet device side plug, simple in structure, easy to use.
Preferred further, insulation barrier adopts square open-core type structure.Insulation barrier adopts open-core type structure, and with bolted on dolly, during use, can be advanced in middle-placed switch cabinet a part ofly, insulation effect is good.
Preferred further, test cart sets gradually railway carriage body, supporting leg and pulley from top to bottom, and instrument standing groove is set in the middle of railway carriage body.Test cart plays support fixation, on dolly, can place test instrument, mobile flexible, is easy to carry.
Preferred further, pulley adopts lockable pulley.Convenient fixing.
Preferred further, the contact area of insulation barrier and test cart is 1/4th to 1/3rd of insulation barrier bottom surface.
The beneficial effect that the utility model has is:
Described high-tension switch cabinet secondary maintenance aviation plug safety extension device in use, operating personnel only need open baffle plate valve and open and plug aviation plug, and by insulating barrier, charging zone is isolated, formed charging equipment fully-enclosed safe operating environment, fully guaranteed personal security, instrument standing groove is set simultaneously, and energy bearing test instrument, makes experiment work more safe and efficient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein, 1, insulation barrier; 2, test cart; 3, baffle plate is opened valve; 4, secondary extension cord; 5, aviation plug; 6, railway carriage body; 7, supporting leg; 8, pulley; 9, instrument standing groove.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figure 1, high-tension switch cabinet secondary maintenance aviation plug safety extension device described in the utility model, comprise test cart 2, one end fixed insulation baffle plate 1 of test cart 2, baffle plate is set in the middle of insulation barrier 1 and opens valve 3, baffle plate is opened in valve 3 secondary extension cord 4 is set, and secondary extension cord 4 two ends connect aviation plug 5.
Wherein, insulation barrier 1 adopts square open-core type structure, and insulation barrier 1 is 1/4th to 1/3rd of insulation barrier 1 bottom surface with the contact area of test cart 2.Test cart 2 sets gradually railway carriage body 6, supporting leg 7 and pulley 8 from top to bottom, and instrument standing groove 9 is set in the middle of railway carriage body 6, and pulley 8 adopts lockable pulley.
Operation principle and use procedure:
When described high-tension switch cabinet secondary maintenance aviation plug safety extension device is used, testing crew is outside switch is pulled out cabinet time, can the aviation plug 5 of extended line one side be inserted on the plug of control box arrangement side by opening baffle plate unlatching valve 3, the aviation plug of opposite side 5 is inserted on switch-side plug, then baffle plate is opened to valve 3 and closed.And by insulating barrier 1, charging zone is isolated, formed charging equipment fully-enclosed safe operating environment, fully guaranteed personal security.The instrument standing groove 9 of the utility model test cart 2 is interior can put test instrument, conveniently protects the work such as verification, switch transmission.Simultaneously, also realize retractable cable freely, the phenomenons such as the mutual winding occurring while avoiding multiple test wire simultaneously to use, in disorder, knotting, have saved maintainer's human cost and time cost greatly, improved overhaul efficiency, avoided hurting test wire in storage, carrying and process of the test.
