Description

Error locking-proof bolt device for high-voltage isolating switch Technical Field The utility model belongs to the field of high-voltage isolating switches, and relates to an anti-misoperation locking bolt device of a high-voltage isolating switch. Background The outdoor high-voltage isolating switch is generally arranged at the inlet end or the outlet end of the transformer substation so as to realize the on or off of the high-voltage circuit. And the partial high-voltage isolating switch adopts an operating handle to control the connection or disconnection of the contact. To avoid false closing of the contacts, a "safety lock" is typically provided at the operating handle and requires that only personnel in direct contact with the high voltage circuit can control to ensure safety. At the current stage, the safety lock can be a self-contained device or a follow-up device of an electric power system, and a mechanical lock is generally adopted, so that the safety lock has the advantages of simple structure and high reliability. But the safety lock is arranged at the outer side of the box body of the high-voltage isolating switch, and the safety lock can not be opened for a long time, so that the problem that the safety lock is rusted or a buttonhole is blocked by dust is often caused under the conditions of long-time vapor corrosion and air hole dust accumulation. Therefore, when maintenance is required, the normal operation is affected due to the difficulty in unlocking the safety lock, and sometimes the safety lock is damaged by a tool.
