[0002] With the rapid development of the economy and the updating of power grid equipment, there are various types of 10kV ring network cabinet equipment at present, including ABB type, FBX type, Ormazabal type, etc. Among them, Schneider's FBX type operating handle is manual type, mainly Relying on the operator to use the operating handle to pull the operating mechanism of the switch cabinet to open / close the ring main unit, it takes a lot of physical strength and wastes a lot of time and energy. Adding extra operating time brings inconvenience to the operation and maintenance of the distribution network
At the same time, when the ordinary operating handle is on the edge of the box shell of the outdoor switch station, due to the narrow space, the operation is more difficult, and it is easy to cause the operator to be injured during the operation.
In addition, when the operator is not tall enough, operating the ring main unit with the normal operating handle adds additional difficulty

Embodiment
[0016] The present invention mainly generates high-frequency PWM modulation pulses with corresponding duty ratios to drive the on-off of the semiconductor switching device Mosfet through a single-chip microcomputer, so that both ends of the motor can obtain a square wave voltage with a corresponding duty ratio and an amplitude of 12V. If it is larger, the average value of the voltage at both ends of the motor will be larger, so the motor speed will be faster, and vice versa, the smaller it will be, so the higher the duty cycle of the high-frequency PWM modulation wave, the faster the motor speed will be. The polarity of the voltage at both ends of the motor can be controlled by the "direction of rotation" switch 7, thereby controlling the direction of rotation of the motor. In actual work, the rotation speed and rotation direction of the motor can be selected according to the actual needs of the site, and the rotation direction of the motor can be judged according to the corres...

A ring network cabinet electric rotation-type operation handle mainly comprises an insulating housing, a miniature direct-current motor, a control circuit board, a lithium battery and a metal operation rod matched with a switch cabinet operation mechanism. The front part of the insulating housing is provided with the metal operation rod connected with the miniature direct-current motor arranged in the insulating housing. The miniature direct-current motor is connected with the lithium battery in an operation handle part of the insulating housing through a rotation direction switch. The control circuit board in the insulating housing is connected with a Mosfet semiconductor switch serially connected between the rotation direction switch and the lithium battery so as to control the rotation speed of the miniature direct-current motor. By adopting the rotation-type operation handle, the operation time of an FBX type ring network cabinet is substantially reduced, the operation and maintenance efficiency of a power distribution network is improved, the breakdown repair time of a power distribution cable network is shortened, the switching off / on operation of the FBX type ring network cabinet is more safely controlled, and the work safety coefficient of operation personnel is improved.
