Abstract
The utility model relates to an interlocking device of a high-tension switch cabinet breaker room. A door lock pin is disposed in a carrying handle of a breaker room front door lock. A spring is disposed on a front end of the door lock pin, and a rear end is movably connected with a boost arm through a lever revolving arm. A boost plate is disposed on two sides of the breaker. When the breaker moves towards a working position, the boost plate and the boost arm are rotatably connected, and a front end of the boost arm contacts and connects with the door lock pin, so that the door lock pin is locked. When the breaker is at the work position, the boost plate clamps the boost arm at a lock position on the lock pin. When the breaker is removed away from the work position, the boost arm is reset through the spring, and the lock pin is unlocked. When a high-tension switch cabinet breaker enters the work position, the interlocking device locks the front door of the breaker room to prevent electric shock. When the breaker does not move back to a test position, the breaker room door is locked by the interlocking device and cannot be opened. When the breaker moves back to the test position, the interlocking device unlocks the breaker room door, and the breaker room door can be opened.
Description
Technical field
The utility model relates to a kind of high-tension switch cabinet, especially a kind of interlock of breaker chamber of high-voltage switch cabinet.
Background technology
The indispensable equipment of high-tension switch cabinet power supply and distribution of electric power during high-tension switch cabinet energising work, guarantees that the staff is not safe Compulsory Feature by electric shock.
When high-voltage switch cabinet breaker enters the service position, be to prevent from shocking by electricity effective measures to the locking of breaker chamber Qianmen.This voltage reducing device namely is the interlock of breaker chamber of high-voltage switch cabinet.
The mode of procedure lock, electromagnetic lock and prompting that also only adopts domestic high-tension switch cabinet reduces the generation of electric shock, and the easy displacement of lock core in long-term keeping of the shortcoming of procedure lock is inaccurate, the inefficacy of easily breaking of electromagnetic lock coil, and no ready-made finished product can be purchased in the market.
Therefore, in developing new product, must design the interlock of trial-production breaker chamber of high-voltage switch cabinet.
Summary of the invention
The utility model is the interlock that a kind of breaker chamber of high-voltage switch cabinet will be provided, when its circuit breaker enters the service position, to the door locking of breaker chamber can not the people for opening; Fall back on from the service position when entering test position at its circuit breaker, to the door release of breaker chamber can the people for opening.
For achieving the above object, the technical solution of the utility model is: a kind of interlock of breaker chamber of high-voltage switch cabinet, comprise lockweight, spring, the lever pivoted arm, support, advance arm, pushing plate, door lock pin, be characterized in: the door lock pin is loaded in the breaker chamber front door lock carrying handle, be provided with spring for the lockweight front end that fastens the door lock pin, the rear end flexibly connects with advancing arm by the lever pivoted arm that is connected on the support, and pushing plate is contained in the circuit breaker both sides, when circuit breaker moves to the service position, pushing plate is rotationally connected with advancing arm, advances the arm front end to be connected with the lockweight contact, makes the lockweight locking, when circuit breaker arrived the service position, pushing plate blocked and advances arm at the lockweight locked position of coupler; When circuit breaker is deactivated the position, advance arm by spring reset, lockweight release.
The lockweight front end is provided with the bayonet lock groove, and the rear end is provided with and hangs pin, hangs the pin outer end and is provided with the bayonet lock groove.
Advancing arm is contact of breaker plate valve arm, and by advancing pin to be connected with the lever pivoted arm.
The beneficial effects of the utility model are:
The utility model is by adopting lockweight, spring, lever pivoted arm, support, advance arm, pushing plate 6, the interlock that the door lock pin is formed, when high-voltage switch cabinet breaker enters the service position, can prevent electric shock to the locking of breaker chamber Qianmen, when circuit breaker did not fall back on test position, the breaker chamber door can not be opened by the utility model locking, the utility model is to the release of breaker chamber door when circuit breaker falls back on test position, and the breaker chamber door can be opened.
