Description

Transforming plant DC earthing searching auxiliary device
Technical field
This utility model relates to transformer station direct current system technical field, is a kind of transforming plant DC earthing searching auxiliary device.
Background technology
Transformer station direct current system refer to the signalling arrangement in transformer station, protection, automaton, emergency lighting and chopper divide, closing operation provide DC source system.If transforming plant DC breaks down very big to whole power system, the safe operation of grid equipment and power supply controllability impact, large-area power-cuts even can be caused.The most common DC system fault is DC earthing; if processing DC ground fault the most in time; second protection automaton malfunction or tripping in station can be caused; chopper that the tripping of mistake is not broken down or the chopper that refusal tripping is broken down, causing large-area power-cuts or the damage equipment of tripping operation of bypassing the immediate leadership.
Summary of the invention
This utility model provides a kind of transforming plant DC earthing searching auxiliary device; overcome the deficiency of above-mentioned prior art; it can effectively solve to process the most in time DC ground fault; cause second protection automaton malfunction or tripping in station; chopper that the tripping of mistake is not broken down or the chopper that refusal tripping is broken down, causing large-area power-cuts or the problem of damage equipment of tripping operation of bypassing the immediate leadership.
The technical solution of the utility model is realized by following measures: a kind of transforming plant DC earthing searching auxiliary device, monitors lamp including housing, air switch, Grounding , It is characterized in that: fixedly mount having air switch on the housing, housing be respectively arranged at two ends with input hole and delivery outlet, the side of housing is provided with earth clip, the input of air switch is electrically connected with through input hole a pair insulating clamp being positioned at hull outside by wire, the outfan of air switch is electrically connected with through delivery outlet by wire and is positioned at a pair of hull outside insulation contact pin, is electrically connected with, between air switch and a pair insulation contact pin, the Grounding being positioned on housing and monitors lamp.
Be presented herein below to foregoing invention technical scheme optimize further or / And improvement:
Above-mentioned air switch is the air switch of band DC leakage protector.
This utility model reasonable and compact in structure, simple to operate, efficiency is high, it can quickly judge the branch road to the ground connection on dc bus, shorten the time that straight-flow system operates with failure, saved the production cost of enterprise, improve the economic benefit of power supply reliability and enterprise.
Accompanying drawing explanation
Accompanying drawing 1 Overall structure schematic diagram for this utility model most preferred embodiment.
Accompanying drawing 2 For circuit theory diagrams of the present utility model.
Coding in accompanying drawing is respectively as follows: 1 For shell, 2 Lamp is monitored for Grounding, 3 For air switch, 4 For input hole, 5 For earth clip, 6 For delivery outlet, 7 For insulating clamp, 8 For insulation contact pin, 9 For dc bus I, 10 For dc bus II, 11 For branch road, 12 For terminal block.
Detailed description of the invention
This utility model is not limited by following embodiment, can determine specific embodiment according to the technical solution of the utility model and practical situation.
Below in conjunction with embodiment and accompanying drawing, this utility model is further described:
Such as accompanying drawing 1 Shown in, this transforming plant DC earthing searching auxiliary device includes housing 1 , Grounding monitor lamp 2 , air switch 3 , at housing 1 Upper fixed installation having air switch 3 , at housing 1 Be respectively arranged at two ends with input hole 4 And delivery outlet 6 , housing 1 Side be provided with earth clip 5 , air switch 3 Input be electrically connected with through input hole by wire 4 And it is positioned at a pair insulating clamp of hull outside 7 , air switch 3 Outfan be electrically connected with through delivery outlet by wire 6 And it is positioned at housing 1 A pair insulation contact pin in outside 8 , at air switch 3 With a pair insulation contact pin 8 Between be electrically connected with the Grounding that is positioned on housing and monitor lamp 2
Can according to actual needs, make above-mentioned transforming plant DC earthing searching auxiliary device to optimize further or / And improvement:
Such as accompanying drawing 1 Shown in, air switch 3 Air switch for band DC leakage protector.
Above technical characteristic constitutes most preferred embodiment of the present utility model, and it has stronger adaptability and optimal implementation result, can increase and decrease non-essential technical characteristic according to actual needs, meet the demand of different situations.
The use process of this utility model most preferred embodiment: when straight-flow system generation DC ground fault, first, housing 1 On earth clip 5 It is clipped on ground connection bronze medal, then through input hole 4 A pair insulating clamp 7 Respectively with the dc bus II that earth fault does not occurs 10 Positive pole and negative pole connect, through delivery outlet 6 A pair insulation contact pin 8 It is inserted respectively into the dc bus I that DC earthing occurs 9 On some branch road 11 Positive supply and the terminal block of negative supply 12 On, after determining that circuit connection is correct, close air switch 3 , disconnected branches 11 Air switch on DC feeder screen, now this branch road 11 Power supply be an other dc bus II 10 It is powered, branch road 11 On all original papers will not dead electricity, observe Grounding monitor lamp 2 , Grounding monitors that lamp does not works, it is judged that this branch road 11 There is ground connection.Thus quickly judge the branch road to the ground connection on dc bus, shorten the time that straight-flow system operates with failure, saved the production cost of enterprise, improve the economic benefit of power supply reliability and enterprise.
