[0019] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0020] Knife switches are mainly used for isolating power supplies, switching operations, connecting and disconnecting small current circuits, and are switch devices without arc extinguishing function. Generally, knife switches are equipped with electric operating mechanisms, which are composed of motors, transmission mechanisms, micro switches, auxiliary switches, etc. The motor drives the worm gear to rotate, so that the knife switch can realize the opening and closing operations through the connecting rod system. After the assembly of the knife switch mechanism is completed, an opening and closing test is required. Usually, the opening and closing test is implemented using a test bench, but the existing opening and closing test method is carried out through a test bench, which has cumbersome wiring and low experimental efficiency. Based on this, the embodiment of the present application provides a new type of simple control device for high-voltage switch knife switches to improve the above-mentioned technical problems.

[0021] In one embodiment, Figure 1 The schematic diagram of the circuit connection of a novel high-voltage switch knife switch simple control device provided in an embodiment of the present application includes an opening and closing contactor and an opening and closing push button switch. The opening and closing contactor includes an opening contactor KMF and a closing contactor KMH, and the opening and closing push button switch includes an opening push button switch SF and a closing push button switch SH.

[0022] like Figure 1 As shown, optionally, one end of the opening and closing contactor is connected to one end of the opening and closing push button switch, and the other end of the opening and closing contactor is connected to the opening and closing contact in the mechanism; the other end of the opening and closing push button switch is connected to the live wire. The opening and closing push button switch is used to control the opening and closing contactor to perform corresponding operations to realize the opening and closing actions of the knife switch mechanism.

[0023] Optionally, the opening contactor KMF is energized when the opening push button switch SF is closed, and is used to control the opening point of the opening contactor auxiliary contact to be pulled in. At this time, the opening contactor KMF remains in the opening state, and the motor rotates in the opening direction. When the opening is completed inside the mechanism, the opening travel switch is disconnected, the opening circuit loses power, and the opening is completed.

[0024] Optionally, the closing contactor KMH is energized when the closing push button switch SH is closed, and is used to control the auxiliary contact of the closing contactor to open and close. At this time, the closing contactor KMH remains in the closed state, and the motor rotates in the closing direction. When the internal closing of the mechanism is completed, the closing travel switch is disconnected, the closing circuit loses power, and the closing is completed.

[0025] Optionally, the opening and closing contactor also has opening and closing contactor auxiliary contacts, which include opening contactor auxiliary contacts and closing contactor auxiliary contacts; and, the opening contactor auxiliary contacts include opening contactor auxiliary open points and opening contactor auxiliary closed points, and the closing contactor auxiliary contacts include closing contactor auxiliary open points and closing contactor auxiliary closed points.

[0026] Optionally, the auxiliary opening point of the opening contactor is connected in parallel with the auxiliary opening point of the closing contactor and is connected to the motor running circuit 1 of the knife switch mechanism; and the auxiliary closing point of the opening contactor is connected in parallel with the auxiliary closing point of the closing contactor and is connected to the motor braking circuit 2 of the knife switch mechanism.

Compared with the existing technical solution, the switch-on and switch-off test method is carried out through a test bench, which has cumbersome wiring and low experimental efficiency.
