Abstract
The utility model relates to maintenance technology of a 10kV/35kV high-voltage switch cabinet and discloses a safety insulating device for a fixed contact of the 10kV/35kV high-voltage switch cabinet, wherein the fixed contact is fixed at the bottom of a first insulating barrel, the safety insulating device comprises an insulating rod and a second insulating barrel which can be turned upside down in the first insulating barrel, an insulating pin is transversely and fixedly arranged at one end which is close to the insulating rod, and a depression which can just contain the end part of the insulating rod and the insulating pin is arranged at the bottom of the second insulating barrel.
Description
Technical field
The utility model relates to the maintenance technique of 10kV/35kV high-tension switch cabinet, particularly a kind of 10kV/35kV high-voltage switch cabinet breaker fixed contact safe insulation device.
Background technology
The high-tension switch cabinet that moves in industry, the 10kV of enterprise, the 35kV transformer station generally adopts the integral structure that totally-enclosed bus connects, the contact contact inserts.The electric fault of operation dolly can be keeped in repair by separating with cabinet, but maintenance, test, troubleshooting do not have safe and reliable locking device in the cabinet.When single high-tension switch cabinet goes wrong (for example: partly break down with operation dolly mechanical engagement), a plurality of parallel high voltage switch cubicles must be forced to stop transport and overhaul it, can cause large-area power-cuts, influence social benefit and client's residential electricity consumption, badly influence normal, the safe operation of system.
Summary of the invention
The purpose of this utility model is to provide a kind of 10kV/35kV high-voltage switch cabinet breaker fixed contact safe insulation device, can conveniently completely cut off the fixed contact of the circuit breaker in the high-tension switch cabinet, prevents that the maintainer from getting an electric shock or injure, convenient maintenance.
In order to achieve the above object, the utility model is achieved by the following technical solutions.
A kind of 10kV/35kV high-voltage switch cabinet breaker fixed contact safe insulation device, described fixed contact is fixed on the bottom of the first insulation bucket, it is characterized in that, described safe insulation device comprises insulating bar and can tip upside down on the second interior insulation bucket of the first insulation bucket, near an end crosswise fixed of described insulating bar one dielectric pin is arranged, the bottom of the described second insulation bucket is provided with the just in time depression of housing insulation boom end and dielectric pin.
Further characteristics of the present utility model are: the peristome of the described second insulation bucket is embedded with the insulating case that covers fixed contact.
Safe insulation device of the present utility model comprises the second insulation bucket and is provided with the insulating bar of dielectric pin near the end, the depression that shape bottom by the second insulation bucket is provided with cooperates with insulating bar end and dielectric pin, and it is interior to completely cut off fixed contact that the second insulation bucket is tipped upside down on the first insulation bucket.The peristome of the second insulation bucket is embedded with the insulating case that covers fixed contact, can realize two minor insulation to fixed contact, the coefficient of safety when improving maintenance.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
Fig. 1 is the scheme of installation of circuit breaker fixed contact in the 10kV/35kV high-tension switch cabinet;
Fig. 2 is the cross-sectional view of the second insulation bucket;
Fig. 3 is the upward view of Fig. 2;
Fig. 4 is the structural representation of figure insulating bar.
Embodiment
With reference to Fig. 1, in high-tension switch cabinet, the fixed contact 2 of circuit breaker is fixed on the bottom of the first insulation bucket 1 by screw 3.With reference to Fig. 2, Fig. 3, the peristome of the second insulation bucket 4 is embedded with insulating case 5, and the inwall of the outer wall of insulating case 5 and the second insulation bucket 4 is a tight fit; The bottom of the second insulation bucket 4 is provided with depression 6.In conjunction with Fig. 4, an end cross near insulating bar 7 is fixed with a dielectric pin 8, the depression 6 of the bottom of the second insulation bucket 4 just in time can housing insulation bar 7 ends and dielectric pin 8, this end of insulating bar 7 can be provoked the second insulation bucket 4 and be tipped upside down in the first insulation bucket 1, and can the second insulation bucket 4 be screwed in the first insulation bucket 1 by dielectric pin 8.At this moment, insulating case 5 covers on the fixed contact 2, reaches fixed contact 2 purposes of the circuit breaker in the isolated high-tension switch cabinet, thereby prevents that the maintainer from getting an electric shock or injure convenient maintenance.
Claims (2)
1. 10kV/35kV high-voltage switch cabinet breaker fixed contact safe insulation device, described fixed contact is fixed on the bottom of the first insulation bucket, it is characterized in that, described safe insulation device comprises insulating bar and can tip upside down on the second interior insulation bucket of the first insulation bucket, near an end crosswise fixed of described insulating bar one dielectric pin is arranged, the bottom of the described second insulation bucket is provided with the just in time depression of housing insulation boom end and dielectric pin.
2. 10kV/35kV high-voltage switch cabinet breaker fixed contact safe insulation device according to claim 1 is characterized in that, the peristome of the described second insulation bucket is embedded with the insulating case that covers fixed contact.
