In the Electric knife switch operation, check no-voltage and splice grafting ground disconnecting link are: distribute and carry out.In a single day the not corresponding of electrical verification lotus splice grafting ground disconnecting link being taken place in the middle of this, promptly causes electric accident: cause the power plant, the large-area power-cuts of electric substation, economic loss is serious! Also may cause casualties.
Existing technology is the substep electrical verification, and splice grafting ground disconnecting link: ground connection disconnecting link and electrical verification do not have positive connection---be the reason that causes the accident.
Summary of the invention
Electrical verification and the not corresponding situation of splice grafting ground disconnecting link take place for fear of in the Electric knife switch operation in the utility model, cause electric accident, and a kind of high pressure check type ground connection disconnecting link is provided.
The utility model is to adopt following technical scheme to realize: high pressure check type ground connection disconnecting link, comprise the electrical verification end and be installed on check disconnecting link on the operating grip base of ground connection disconnecting link, the electrical verification end comprises supports pedestal, firm banking, rotation semi-disc and the leading screw that is connected that is used for fixing telescopic High-Voltage Insulation electrical verification rod, support that pedestal is fixed on the firm banking, connect leading screw and be fixed on the rotation semi-disc, rotate semi-disc and be fixed on the support pedestal by rolling bearing; The check disconnecting link comprises the pedestal on the operating grip base that is installed on the ground connection disconnecting link, is fixed with semi-disc by rolling bearing on the pedestal, and operating grip is fixed on the semi-disc; The rotation semi-disc of electrical verification end with the check disconnecting link operating grip between be connected steel wire rope.Steel wire rope is supported by angle bar, and angle bar is provided with three and is used to realize steel wire rope connection, the deflecting roller that turns to.
The utility model installs a cover verifying attachment additional on the basis of ground connection disconnecting link---promptly check disconnecting link.Operating grip band one semi-disc of check disconnecting link, its semi-disc moves, and just in time plays the effect of the handle of sealing and releasing ground connection disconnecting link.Utilize this relation, we can be contained in the base of check disconnecting link on the operating grip base of ground connection disconnecting link.With the linkage of a cover angle bar and steel wire rope, drive other end electrical verification end.The electrical verification end is connected with telescopic electrical verification rod by leading screw, performance tests disconnecting link handle, electrical verification rod promptly can with the three-phase of ground connection disconnecting link, ABC goes between and contacts respectively, reaches the purpose of electrical verification.The disconnecting link of electrical verification is exactly this ground connection disconnecting link like this, can not make mistakes!
We have designed the support pedestal electrical verification end, and firm banking rotates semi-disc and is connected leading screw.High-Voltage Insulation electrical verification rod is connected on the leading screw, and leading screw is fixed on the semi-disc.
Steel wire rope is connecting semi-disc and the operating grip of checking disconnecting link, and the angles that the semi-disc of dependence operating grip turns over 130～180 degree reach sealing and open, the purpose of ground connection switch operation handle.
The check disconnecting link base of check disconnecting link and the check disconnecting link base of ground connection disconnecting link are bases.
Check disconnecting link check disconnecting link is fixed on the base with pedestal, and the check disconnecting link is by operating grip and semi-disc, and pedestal is formed, and operating grip is welded on the semi-disc.
During the operating grip of performance tests disconnecting link, steel wire rope interlock electrical verification end semi-disc, its semi-disc turns over the angle of 130～180 degree, the High-Voltage Insulation electrical verification rod that is connected with leading screw also turns over the angle of 130～180 degree, during this time respectively with the three-phase of ground connection disconnecting link, electrical verification has been carried out in the contact respectively of ABC lead-in wire.
All there is rolling bearing at two semi-disc centers of this check disconnecting link, and two semi-discs all are connected with steel wire rope.Steel wire rope is supported by angle bar, and three deflecting rollers are arranged on the steel wire rope, realizes connecting and turning to.
This checks disconnecting link, use be telescopic High-Voltage Insulation electrical verification rod, its contact-ferrule is the elastic metallic head, can be under stressing conditions, about turn over 90 degree.
The recovery of this check disconnecting link is to rely on manually to recover.After the ground connection disconnecting link drew back, ground connection disconnecting link handle returned to original position, manually recovered to connect leading screw and the operating grip of checking disconnecting link, the route of the operating grip motion of closed again ground connection disconnecting link.
The utility model is simple and reasonable for structure, and result of use is good, misoperation occurs in the time of effectively avoiding closed ground connection disconnecting link, and safe and reliable guaranteeing role is played in the Electric knife switch operation when being applicable to electric power system high-tension apparatus interruption maintenance.
