35kv switchgear isolation baffle mechanical locking device

Abstract

The invention relates to a 35kV switchgear isolating baffle plate mechanical blocking apparatus mainly comprising a blocking device, a blocking member 1, a blocking hole, a blocking member 2, a holding spring, a blocking pin, a hole 1, a blocking spring, a hole 2, a bus contact isolating baffle plate, a line contact isolating baffle plate, a repositioning spring, a shaft, an interlocking sheet, an interlocking column, a lock hole, and a connecting hole. The blocking member 2 is connected with the blocking pin and the connecting hole. The blocking member 1 is equipped with the blocking hole. The holding spring is arranged in the hole 1. The blocking spring is arranged in the hole 2. The blocking member 1 is installed in the holding spring in the hole 1, then the blocking member 2 is installed in the blocking spring in the hole, and finally the blocking hole end of the blocking member 1 is installed in the connecting hole of the blocking member 2 and blocking pin is inserted into the blocking hole in order to achieve blocking. One end, installed on the shaft, of the repositioning spring is arranged on the interlocking sheet. The other end of the repositioning spring is arranged on the line contact isolating baffle plate. The shaft is installed on the line contact isolating baffle plate. The interlocking column is installed on the bus contact isolating baffle plate. The interlocking sheet is arranged on the shaft to be interlocked with the interlocking column. Compared with a product in the prior art, the 35kV switchgear isolating baffle plate mechanical blocking apparatus is simple in structure and reliable and firm in blocking.

Description

technical field [0001] The invention mainly relates to the field of mechanical locking of an isolation baffle of a switch cabinet, and mainly relates to a mechanical locking device for an isolation baffle of a 35kV switch cabinet. Background technique [0002] The busbar contacts and line contacts are respectively installed in the 35kV switchgear of the substation. When the handcart switch is overhauled, both the busbar contacts and the line contacts are live. Personal safety, separate baffles for bus contacts and line contacts are installed in the 35kV switchgear to ensure personal safety. Due to design defects, there is currently no mechanical locking device for the isolation baffles of busbar contacts and line contacts in the 35kV switchgear. The staff can open the isolation baffles in the switch cabinet anytime and anywhere, and there is no lock to prevent unauthorized opening of the isolation baffles of the switch cabinet. device. On October 19, 2013, when an electric...
