Abstract

The invention discloses an electromagnetic locking device for a ground knife operation hole of a ring network cabinet, which comprises a controller, a voltage sensor electrically connected with the controller through a signal line and a shielding mechanism. The shielding mechanism comprises a driving part and a shielding plate connected with the driving part. Wherein, the voltage sensor is used for detecting the voltage signal of the cable and transmitting the voltage signal to the controller through the signal line, and the controller is used for receiving the voltage signal and judging whether the cable is charged or not according to the voltage signal; And controlling the driving part of the shielding mechanism to drive the shielding plate to move to a preset first position when the cable is charged so that the shielding plate shields the ground knife operation hole of the ring net cabinet, and controlling the driving part of the shielding mechanism to drive the shielding plate to move to a preset second position so that the shielding plate does not shield the ground knife operation hole of the ring net cabinet when the cable is not charged. The implementation of the applicationcan solve the technical problem that the ground knife of the ring network cabinet is misoperated under the condition of being charged.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to an electromagnetic locking device for a ground knife operating hole of a ring network cabinet. Background technique [0002] During the operation and maintenance of the ring network cabinet, due to the cumbersome process, the operator needs to strictly abide by the operation process, and the number and types of the 10kV distribution network ring network cabinet are numerous, the operating mechanism is inconsistent, and the charging display device is often burned out, which cannot normally display whether the cable is charged. . The anti-misoperation protection measures are insufficient and the safety is low. Once the operation is wrong, it will cause the line to trip, the user will lose power, and in severe cases, arc discharge will occur, which will burn the staff and cause heavy losses. Contents of the invention [0003] The purpose of the present invention is to pro...
