Description

Technical Field

[0001] The invention relates to the technical field of electrical maintenance, and in particular to an electric remote-controlled arc-extinguishing switch device for live working in a distribution network. Background Art

[0002] According to the "10kV Distribution Network Non-stop Operation Specifications": When disconnecting and connecting no-load lines under power, the no-load current should not exceed 5A. When it exceeds 0.1A, special tools such as arc-extinguishing switches and operating levers for live operations should be used. Figure 1 As shown. During the fire connection operation, under the condition that the operator maintains a sufficiently safe distance from the live body, first hold the insulating operating rod to close the arc extinguishing switch, then move to the fire connection position on the other side of the pole to fix the lead wire to be connected on the main conductor, and then move back to the work station to open the arc extinguishing switch to complete the fire connection operation. The entire process requires operators to frequently transfer positions. In order to maintain a sufficient and appropriate safety distance, a lot of time is consumed, resulting in low work efficiency, and the same is true for fire shearing operations. According to statistics, live shearing and fire connection operations account for more than 50% of live distribution network operations, which increases the labor intensity of personnel and reduces work efficiency. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides an electric remote-controlled arc extinguishing switch device for live distribution network operations. The electric arc extinguishing switch can be remotely operated, so that the operator can complete the opening and closing operations of the arc extinguishing switch at the fire connection position, which greatly saves the time required for transferring work stations and improves work efficiency.

[0004] In order to solve the above technical problems, the present invention provides a technical solution: an electric remote-controlled arc-extinguishing switch device for live working of a distribution network, comprising an arc-extinguishing switch, a fixed housing, a control component and an electric screw, characterized in that: the fixed housing is fixed to the pole of the arc-extinguishing switch by a clamp, the control component and the motor end of the electric screw are arranged in the fixed housing, and the telescopic end of the electric screw is hinged to the handle of the arc-extinguishing switch; The control component comprises a forward and reverse controller, a remote controller, and a power supply. The power supply is electrically connected to the electric screw rod through the forward and reverse controller, and the remote controller is wirelessly connected to the forward and reverse controller.

[0005] Furthermore, the fixed shell and the clamp are an integral structure or hinged, and a shell cover is detachably connected to the fixed shell via screws.

[0006] Furthermore, the electric screw is fixed in the fixed housing by means of buckles and screws.

[0007] The beneficial effects of the present invention are: 1. The present application adds a remote control device to the existing arc extinguishing switch, and operates the arc extinguishing switch handle through the forward and reverse rotation of the motor to complete the remote control operation of opening and closing the arc extinguishing switch. The electric remote control arc extinguishing switch device enables the operator to complete the opening and closing operation of the arc extinguishing switch directly at the ignition position, shortening the entire operation time and improving the overall work efficiency.

[0008] 2. Through remote operation, the operator can operate the arc extinguishing switch while maintaining a sufficiently safe distance from the live object, reducing the risk of close contact with live equipment and further ensuring the safety of the operator.

[0009] 3. The electric operating mechanism of the present application replaces the traditional manual operation, reduces the dependence on manpower, and at the same time reduces the work and fatigue caused by manual operation, and improves the working accuracy and reliability.

[0010] 4. This application has a simple design and is easy to use. It can be easily operated even in complex environments, such as high altitudes or narrow spaces, thus maximizing the flexibility of live working.

[0011] 5. This application improves operating efficiency and reduces dependence on manpower. The present invention can effectively reduce construction costs and improve the economic benefits of the power system.
