Description
Technical field
The utility model belongs to the 10kV high-tension switch cabinets field such as substation, power distribution station more particularly to a kind of switchgear is small
Vehicle loop fault detects and searches device.
Background technology
10kV high-tension switch cabinets are the high-tension switch gears that substation directly contacts with user, and operating current is big, changes
Fast and back brake is frequent, easily breaks down.Mechanical breakdown is common in close to divide, be unable to separating brake etc. and is easier to exclude event on switchgear
Barrier, Major Difficulties are still in electric fault.There are following several sides when searching and handling the electric fault on switchgear at present
Method：
1, (secondary circuit electrification) is searched in electrification.When charging trouble shoot, equipment original state should be adjusted to spring not
Energy storage, breaker are in open position, trolley is in the state of testing position, then input control power supply and accumulation power supply,
Each point break-make situation is examined according to secondary connection loop figure using multimeter voltage gear under conditions of electrification, according to each point
The actual potential of current potential and the difference of theoretical potential come the position of failure judgement.Charging lookup method, there are two main problems：
1. electrification, which is searched, can not handle short-circuit electric fault, if there are short-circuit failures in circuit, the step of failure is looked into according to electrification
Suddenly the result showed often results in tripping, seriously endangers equipment safety.2. electrification is searched, there are electrical shock safety hazards, due to being
Troubleshooting is charged, there is the artificial wind for sealing in electric loop or ground short circuit failure being caused to cause ground short circuit in operation
Danger, is unfavorable for the safety of power grid, the person, equipment.
2, bulk loop continuity check.Troubleshooting or power-off fault processing are either charged, 58 core air plugs are limited by
Not easy-operating limitation, secondary circuit failure investigation, which is often taken, shakes trolley to testing position, generally right with secondary circuit
As the form checked successively each point break-make.Since circuit relates generally to two parts of cabinet and trolley on switchgear, lead
Cause to need artificially two parts of cabinet and intermediate trolley cabinet play progress loop check back and forth above switchgear when operation, but
It can not failure judgement position be disposably inside trolley on earth or the cabinet part on switchgear, be unfavorable for the exclusion of failure,
Influence working efficiency.
3, air plug positioning break-make measures.Before carrying out mechanical property and loop resistance testing process, need to haul out in trolley
Malfunction elimination is individually carried out, just has to carry out troubleshooting by unique object of trolley at this time.58 core air plugs are limited by be not easy
Operating feature both can not directly judge also in known deposit can not in the case of a fault facilitate with the presence or absence of failure in trolley at this time
Ground carries out troubleshooting, and general processing method is that a hand-held air plug finds circuit beginning air plug contact pin and connect with multitester probe
It touches, another hand comes on trolley back into row each point continuity check.This method is extremely inconvenient, pole non insurance and very time consuming,
The exclusion efficiency of failure can be seriously affected in accident rush repair place, influences the activity duration.
Utility model content

A major loop detects indicator light, respectively combined floodgate indicator light, separating brake indicator light and energy storage indicator light, also has on described device panel
Three subsidiary loop detection pile crowns and five major loops help and look into pile crown, wherein three subsidiary loops detection pile crown is respectively
Red light circuit pile crown, green light circuit pile crown and test loop pile crown, five major loops help look into pile crown be respectively combined floodgate end, point
Lock end, energy storage end, common end and auxiliary end of closing a floodgate, described device further include power supply, resistance and function switch switch, institute
It states three subsidiary loops detection pile crowns and five major loops helps and look into pile crown and be respectively connected to corresponding jack on female plug panel, three
One pin of a major loop detection indicator light, which is respectively connected to corresponding major loop, to be helped and looks into pile crown, another pin passes through function
Switching switch, resistance, power supply are connected to the common end jack on female plug panel.
Further, the power supply voltage is 9V.
Further, the major loop detection indicator light is light emitting diode.
The utility model has the beneficial effects that：This switchgear trolley loop fault detects and searches device can be not charged
In the case of three big major loop of trolley and auxiliary quickly judged by the state change of indicator light and the detection pile crown of several extractions
It whether there is electric fault in circuit, if it has been determined that trolley passes through helping for several extractions there are in the case of electric fault
The quick investigation that pile crown greatly facilitates failure is looked into, to avoid the contact pin to 58 core air plug of trolley from directly being operated, is effectively subtracted
The risk of few loop fault processing, significantly improves loop fault search efficiency.
