Electric high-voltage switchgear high-voltage handcart electric operating device

Abstract

An electric operating device for a high-voltage handcart of an electric high-voltage switchgear, including a mechanical cart and an adjustable support balance frame, the mechanical cart and the adjustable support balance frame are connected by an adjustable screw; the bottom of the mechanical cart is equipped with a pulley and a power supply The adjustable supporting balance frame is provided with a motor, the output shaft of the motor is connected with the rotating shaft transmission rod, and the end of the rotating shaft transmission rod is provided with a replaceable slotted head. The operation method of the invention is simple and safe, the operation is convenient and convenient to move, and the speed is uniform when the electric operation handcart switch is performed, which meets the requirements of the switch manufacturer. When centralized overhaul test and new installation and commissioning of multiple high-voltage handcart switches, high-intensity continuous and frequent operations can be performed in a short period of time, with low loss, high economic benefits, safety, and labor-saving operators.

Description

technical field [0001] The invention belongs to the technical field of electric equipment, and in particular relates to an auxiliary device for a high-voltage handcart of an electric high-voltage switch cabinet. Background technique [0002] At present, the 3-35kV power high-voltage switchgear in China's power system is mostly assembled with the power high-voltage switchgear to form an AC metal-enclosed switchgear, which is widely used in substations, switching stations, distribution stations and other places in the power system as receiving and It is used for distributing electric energy, switching on and off the load current, especially suitable for places with frequent operations. [0003] This kind of closed metal shell cabinet structure prevents high-voltage live switches, busbars, outgoing cables and other auxiliary live parts from being exposed to the outside air, and can ensure that workers are safely and reliably isolated from live equipment during work and maintain...

AI Technical Summary

Problems solved by technology

[0006] Disadvantages of the above operation method: 1. The handcart switch is very heavy. Generally, the 35kV handcart switch weighs about 500 kg, and the 10kV handcart switch weighs about 200 kg. In operation, manual and mechanical shaking operation is still laborious, especially when operating multiple handcart switches continuously. In the case of fewer operators, it is a test for the physical strength of the operators. At the same time, in this case, it is also necessary Will indirectly affect the safety of the operator's work

[0007] 2. The handcart switch and the track will have a certain friction force under the action of gravity. If the high-voltage switch cabinet is not assembled well, the high-voltage handcart switch and the track are not well connected, the friction will be greater, and the operation will be more difficult. Laborious, not conducive to smooth operation

[0008] 3. The track stroke is long, the shaking operation time is long, and the operation time is delayed
