A kind of 10kv switch cabinet convenient electric inspection auxiliary device

Abstract

The invention relates to the field of electric power technology, and particularly to a 10kV switchgear convenient electric checking auxiliary device. The 10kV switchgear convenient electric checking auxiliary device comprises an operating component and a grounding wire operating rod. The operating component comprises a fixed sleeve, a cross-shaped fixing frame and a universal shaft coupling. One end of the cross-shaped fixing frame is fixed on the inner wall of the fixed sleeve. Two sides of the fixed sleeve are provided with telescoping devices. The telescoping device comprises driven bevel gears which are arranged at two ends of the cross-shaped fixing frame, a driving bevel gear which is arranged at a reset end and matches the driven bevel gear, a screw rod which is connected with the driven bevel gear, and a telescopic rod which is in threaded connection with the screw rod. The driven bevel gears and the driving bevel gear are rotatably connected with the cross-shaped fixing frame.The center of the driving bevel gear is vertically connected with a rotating shaft. The rotating shaft is connected with a grounding wire operating rod through the universal shaft coupling. The 10kVswitchgear convenient electric checking auxiliary device has advantages of simple structure, convenient operation, easy carrying, high practicability, high operation efficiency and wide application range.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a portable electric inspection auxiliary device for a 10kV switch cabinet. Background technique [0002] With the development of the economy, the demand for power systems is getting higher and higher. 10KV trolley switchgear is widely used in power plants, substations, industrial and mining enterprises and other places. Due to the needs of power grid construction and maintenance, its switching operations are also very frequent. The 10KV trolley switchgear is a fully enclosed switchgear, which cannot be directly tested by contacting the conductor through the electroscope. The traditional electric test method is generally: push the electric test trolley into the switch cabinet, and use the push mechanism at the front of the electric test trolley to touch the switchgear. Touch the control ejector rod of the baffle switch, open the closed baffle that covers the contacts, and ...

Problems solved by technology

However, the existing electric inspection trolley is very heavy, the operation intensity is high, and the efficiency of direct electric inspection of the switch cabinet is very low. Generally, it takes at least 20 minutes to complete an electric inspection operation, which is time-consuming and laborious, and it is easy to cause personal injury during operation.

[0003] For example, the Chinese patent announcement number is: CN 203553678 U, which was announced on April 16, 2014 for the push rod used for the electric test of the switch cabinet, which consists of an insulating rod, a cross bar, a contact, a support arm, a vertical rod, a horizontal shaft, and a roller. Composition, its structure is simple, small in size, light in weight, easy to carry, safe and reliable in use, but the scope of use of the device is greatly limited, and it is not possible to conduct electrical inspections on switchgears of different widths and lengths
