Background
An air switch, also called a miniature circuit breaker, has the functions of short-circuit protection, overload protection and the like, is widely applied to daily production and life of people, and is particularly obvious to be applied to an electric power system, such as a station alternating current power distribution system, bus and line voltage, a direct current protection (control, energy storage and signal) system and the like.
In the power system, the operation state of the secondary equipment changes due to the change of the operation mode, so that the on-off state of each air switch is different under a specific operation state, and the following two cases can be divided into: 1. the air switch which is in an off state during normal operation comprises the following components: (1) the air switch of the energy storage ring network is forbidden to be switched on at any time when two sets of direct current systems are configured; (2) the disconnecting switch operation power supply and the motor power supply need to be allowed to be switched on before operation of an operator, and the like. 2. The air switch that can not miss when having a power failure and overhauing combined floodgate has: (1) when the line is in power failure, the line voltage air switch is strictly forbidden to be switched on; (2) the energy storage power supply and the control power supply air switch which are in power failure maintenance interval forbid closing, and the like. If the air switch which is forbidden to be switched on in the power system is in a switched-on state due to misoperation of personnel, insufficient technical skill level of the personnel and other reasons, personal electric shock or equipment damage and the like can be caused.
At present, a transverse locking hole for forbidding closing is designed between a thermoplastic shell of most air switches and an insulating handle, and a needle transversely penetrates through the locking hole to prevent the insulating handle from moving upwards so as to fulfill the aim of forbidding closing of the air switches. This design is feasible when moving to single or two switches, and if the switch quantity is greater than the empty locking hole of opening in the middle of the three hours and will be unable to use, gives daily fortune dimension, and the power failure overhauls and brings very big risk, if the switch mistake closes a floodgate will lead to the person to electrocute or equipment damage when serious.
