Embodiment Construction

[0014] Such as Figure 1~3 As shown, a high-voltage circuit breaker advances the closing lock device, including a chassis 1 for installing the circuit breaker, and a circuit breaker installation panel 2 with an opening and closing switch for controlling the opening electromagnet 3 and the closing electromagnet 4 The knob 5 and the mounting panel can move back and forth relative to the chassis to switch the circuit breaker between the working position and the test position. The driving end of the opening electromagnet 3 is pierced with an opening and tripping lever 6 that can be pulled upward to realize opening. A stop pin 7 is arranged on the opening and closing knob 5, and a locking plate 8 that can swing up and down and has a hook 9 is hinged on the mounting panel. The opening and closing knob 5 turns to control the closing direction; it also includes an interlock mechanism that controls the locking plate 8 to swing up and lifts the opening and tripping lever 6 upwards to re...

Abstract

The invention relates to a high-voltage circuit breaker push-to-close latching device comprising a chassis for mounting a circuit breaker. A mounting panel of the circuit breaker has an opening and closing knob for controlling an opening electromagnet and a closing electromagnet. A drive end of the opening electromagnet is provided in a penetrating manner with an opening trip lever which is pulled up to realize opening. The opening and closing knob is provided with a stop pin thereon. The mounting panel is hinged with a latching plate which can swing up and down and has a hook portion. The latching plate swings up and then the hook portion and the stop pin are cooperated to limit the rotation of the opening and closing knob in a closing control direction. Also included is an interlocking mechanism for controlling the latching plate to swing up when the circuit breaker moves from a test position to a working position and raising the opening trip lever to realize opening. The high-voltage circuit breaker push-to-close latching device of the invention ensures that the circuit breaker is stably in an opening state when pushing from the test position to the working position, prevents false switching and eliminates safety hazards.

Description

technical field [0001] The invention relates to a high-voltage circuit breaker push-on closing locking device. Background technique [0002] When the high-voltage circuit breaker is advancing from the test position to the working position, it should be in the open state stably, and the circuit breaker cannot be closed. If the device is pushed to the working position, there will be a great potential safety hazard. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a safe and reliable high-voltage circuit breaker push-on closing locking device, which ensures that the circuit breaker is in the open state during the process of advancing from the test position to the working position, prevents false closing, and eliminates potential safety hazards . [0004] The present invention is realized by the following scheme: a high-voltage circuit breaker push-on closing locking device, including a chassis for installing the circuit ...
