| description | The invention discloses a live display device of an explosive-proof series vacuum switch and a working method of the live display device. The vacuum switch comprises a wiring cavity and a main cavity; the live display device comprises an electronic lock and an indicator lamp; the electronic lock and the indicator lamp are connected with a control loop of the wiring cavity in series in sequence; the electronic lock is further connected with a control power supply of the wiring cavity; the electronic lock is provided with a display state and a connection state; when the electronic lock is in the display state, the control loop of the wiring cavity is disconnected and the indicator lamp shines; when the electronic lock is in the connection state, the control loop of the wiring cavity is connected. Through connecting the electronic lock and the indicator lamp in the control loop of the wiring cavity in series, switching the state of the electronic lock by utilizing a key so as to control the connection or disconnection of the control loop of the wiring cavity, and displaying the state change through the indicator lamp, operators can clearly see the on-off state of the vacuum switch so as to prevent the possibility of false power transmission or misoperation caused by unclear switch state, and the safety production is powerfully ensured. |
