Abstract
The utility model belongs to the parts of equipment for power transmission and distribution, relates to a kind of circuit breaker Qu Jin mechanism locking device.Comprise the screw mandrel in cabinet, circuit breaker cart, Qu Jin mechanism and screw, described Qu Jin mechanism drives circuit breaker cart to arrive service position or away from service position; Elastic device is provided with between the front end face of described circuit breaker cart and the inwall of cabinet, when circuit breaker cart is close and arrive service position, described elastic device can give circuit breaker cart one active force backward, thus the gap of eliminating between screw mandrel and screw, ensure moving contact and fixed contact reliable contacts.
Description
Technical field
The utility model relates to circuit breaker cart Qu Jin mechanism locking device.
Background technology
middle pressure withdrawing switch apparatus adopts the cooperation of leading screw and screw drive into or displace circuit breaker cart; Usually certain fit clearance can be designed with between leading screw and screw.When circuit breaker cart is in service position, and frequently to carry out point, closing operation, produce vibration.Therefore leading screw and screw plant vibration for a long time, relative movement can be produced each other at axial direction, this moving belt moves circuit breaker cart and moves together, thus easily cause the dynamic and static contact virtual connection of switchgear to be touched, switching devices brings great potential safety hazard, therefore and occur security incident also of common occurrence.
Therefore, a kind of withdrawing switch apparatus that can ensure dynamic and static contact reliable contacts is needed.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of circuit breaker Qu Jin mechanism locking device that can ensure dynamic and static contact reliable contacts.
Circuit breaker Qu Jin mechanism of the present utility model locking device, comprises the screw mandrel in cabinet, circuit breaker cart, Qu Jin mechanism and screw, and described Qu Jin mechanism drives circuit breaker cart to arrive service position or arrives test position away from service position; Elastic device is provided with between the front end face of described circuit breaker cart and the inwall of cabinet, when circuit breaker cart is close and arrive service position, described elastic device can be given circuit breaker cart one active force backward thus eliminates thus eliminate the gap between screw mandrel and screw, ensure moving contact and fixed contact reliable contacts, avoid because moving contact and fixed contact virtual connection are touched and security incident is occurred.
Described circuit breaker cart front end face is provided with a stop collar, elastic device comprises the spacer pin of the level be fixedly mounted on cabinet inwall, and on described spacer pin, cover has spring; When circuit breaker cart is close and arrive service position, described spacer pin stretches in stop collar, and spring contacts with the front end face of circuit breaker cart, and is compressed.
The end of described spacer pin is provided with guiding end face, is convenient to spacer pin and stretches in stop collar.
Accompanying drawing explanation
Fig. 1 is the structural representation of circuit breaker cart of the present utility model when being in test position;
Fig. 2 is the structural representation of circuit breaker cart of the present utility model when being in service position.
Embodiment
As shown in Figure 1: a kind of circuit breaker Qu Jin mechanism locking device, comprises the screw mandrel 3 in cabinet 1, circuit breaker cart 2, Qu Jin mechanism and screw 4, described Qu Jin mechanism drives circuit breaker cart 2 to arrive service position or arrives test position away from service position;
The front end face of described circuit breaker cart 2 is provided with a stop collar 6, the spacer pin 7 of the level on cabinet 1 inwall, the end of described spacer pin 7 is provided with guiding end face 5.On described spacer pin 7, cover has spring 8.
As shown in Figure 2: when circuit breaker cart 2 is close and arrive service position, described spacer pin 7 stretches in stop collar 6, spring 8 contacts with the front end face of circuit breaker cart 2, and compressed, to circuit breaker cart 2 one active force backward, thus the gap of eliminating between screw mandrel 3 and screw 4, ensure moving contact 10 and fixed contact 9 reliable contacts.
