Description
Technical Field
The utility model belongs to the technical field of electrical engineering, and relates to a guiding device for breaker operation.
Background
In the case of a fixed-partition low-voltage switchgear or other circuit breaker switching-on/off operation using a rotary handle on a door that can be opened/closed, the rotary handle is mounted on a door surface, and an operating mechanism mounted on a circuit breaker body is spaced from the door surface by a certain distance, and is required to be driven by a connecting rod. One end of the connecting rod is inserted into the groove of the operating mechanism and is fixed by a jackscrew so as not to fall off. The other end is suspended, and is inserted into the groove of the rotary handle when the cabinet door is closed, so that a transmission device is formed, and an operator is ensured to perform opening and closing operation of the circuit breaker through rotating the operation handle from outside under the condition that the cabinet door is closed. However, because the connecting rod is a steel solid core, the suspended end falls under the action of dead weight, and therefore, the connecting rod cannot be accurately inserted into the groove of the rotary operating handle in the closing process of the cabinet door. Requiring manual lifting when the door is closed to insert the twist grip recess. In general, when one end of the connecting rod is suspended and is about to be inserted into the groove of the rotary handle, the door is in a state about to be closed, and at the moment, the opening and the angle of the door are extremely small, and the lifting of the connecting rod is very difficult, so that an operator has to frequently and rapidly close the door to try to push the connecting rod into the groove of the rotary handle. This presents a great inconvenience to the operator, and frequent forced closing attempts to squeeze the lever can lead to premature failure of the mechanism.
Disclosure of Invention
The utility model aims to solve the problems in the prior art, and provides a guiding device for breaker operation, which solves the problem that the prior cabinet door cannot be accurately inserted into a groove of a rotary operation handle in the closing process.
For this purpose, the utility model adopts the following technical scheme:
the utility model provides a guiding device for circuit breaker operation, includes moulded case circuit breaker (7), the lateral part of moulded case circuit breaker (7) is equipped with operating handle face (6) and cabinet door side (4), and the two links to each other through the hinge, operating handle face (6) are equipped with extension rod (2), cabinet door side (4) correspond the position department of extension rod (2) and are equipped with L type guide board (1), guide board (1) are the slope setting, and its department of bending is parallel form with cabinet door side (4), and its contained angle with cabinet door side (4) top is 20-40 degrees, be equipped with handle recess (3) directly over guide board (1).
Further, the extension rod (2) is influenced by self gravity in an initial state, and the end part of the extension rod is sagged.
Further, an operating handle (5) is arranged on the other side of the cabinet door side (4).
The utility model has the beneficial effects that:
according to the utility model, the guide plate with the inclination angle is arranged below one side of the operating handle facing the circuit breaker, and the operating mechanism connecting rod drooping due to self gravity firstly touches the guide plate in the closing process of the cabinet door, and after sliding along the angle of the guide plate, the operating mechanism connecting rod is forced to be lifted to be horizontal, so that the sagging due to gravity is overcome, the operating mechanism connecting rod is accurately inserted into the groove of the rotating handle, and the problem that the operating mechanism connecting rod cannot be inserted into the positioning groove of the rotating handle when the cabinet door is closed is avoided. The utility model has the advantages of simple structure, stable and reliable performance, convenient assembly and low cost.
