Problems solved by technology

This circuit breaker has a disadvantage. When some special circumstances, such as bad weather, need to keep the circuit breaker off, anyone can close the circuit breaker, even accidental non-human actions can close the switch. Therefore, it is easy to cause wrong closing, threatening people's lives and property safety.

Embodiment Construction

[0018] In the following, an indoor high-voltage vacuum circuit breaker of the present invention will be further described with reference to the accompanying drawings.

[0019] Such as figure 1 , figure 2 , image 3 As shown in the figure, the indoor high-voltage vacuum circuit breaker of this embodiment includes a housing 1, a closing bending plate 18, an opening detent 16 and an opening detent sub-shaft 17, as well as a control closing bending plate 18 and an opening detent. The circuit of the sub 16 and the opening detent sub shaft 17, the circuit breaker is also provided with a lock mechanism 3 and a transmission mechanism controlled by a key 31, and the circuit is provided with a switch 2. In this embodiment, the switch 2 is a micro Switch, the switch 2 is used to control the switch of the electric lock circuit. When the key 31 opens the lock mechanism 3, the key 31 cannot be removed from the lock mechanism 3, and the lock mechanism 3 makes the switch 2 in the closed state, b...

Abstract

An indoor high-voltage vacuum circuit breaker comprises a shell, a switching-on bending plate, a switching-off pawl, a switching-off pawl shaft, and a circuit for controlling the switching-on bending plate, the switching-off pawl and the switching-off pawl shaft, wherein the breaker also comprises a locking mechanism on the shell and a transmission mechanism acted with the locking mechanism; said locking mechanism is provided with a guide rod; the circuit is provided with a switch; the switch and the transmission mechanism are corresponding to the position of the guide rod; the transmission mechanism includes a first transmission mechanism which is correspondingly acted on the switching-off pawl shaft and is driven to rotate, and a second transmission mechanism whose tail end is provided with a locking piece; said locking piece has two mutually converted position states, one state is a first position that is separated from the switching-on bending plate and does not interacted with the switching-on bending plate, and the other state is a second position that is cooperated with the switching-on bending plate block chip and prevents the switching-on of the switching-on bending plate block chip. The breaker is controlled via a locking mechanism without misoperation.

Description

Technical field [0001] The invention relates to a circuit breaker, in particular to an indoor high-voltage vacuum circuit breaker. Background technique [0002] The indoor high-voltage vacuum circuit breaker is a circuit breaker whose contacts are opened and closed in a high vacuum bubble. The existing indoor high-voltage vacuum circuit breakers include the closing bending plate, the opening detent and the sub-axle of the opening detent, and the circuit that controls the closing deflection plate, the opening detent and the sub-axle of the opening detent can be manually or electrically operated. To make the opening detent and the sub-axle of the opening detent and the closing of the bending plate close, and then through the opening of the opening detent and the sub-axle to make the circuit breaker open, or close the bending plate to make The circuit breaker is closed. This circuit breaker has a shortcoming. In some special circumstances, such as bad weather, it is necessary to k...
