Abstract

The invention discloses a split type misoperation preventing device for secondary equipment of a transformer substation and a protection method implemented by the split type misoperation preventing device, and relates to the field of protection devices for equipment. The split type misoperation preventing device is characterized in that strip-shaped gaps are reserved on the side walls of a stretching device, one end of a shelter is fixedly wound on the stretching device via the strip-shaped gaps, the shelter can be stretched under the control of the stretching device, the other end of the shelter is fixedly adhered on a pulling pressure plate, an outward semicircular protrusion is arranged in the middle of the pulling pressure plate, a lock hole is formed in the protrusion, a misoperation preventing lock can be inserted into the lock hole, the lock hole can be locked by the misoperation preventing lock, and soft magnets are arranged at the upper end and the lower end of the pulling pressure plate and are used for fixing the pulling pressure plate onto the secondary equipment. The split type misoperation preventing device and the protection method have the advantages that problems of influence of secondary measures arrangement modes on the power supply reliability, time and labor wastage during work, insufficient firmness and low work efficiency of existing transformer substations can be solved; the split type misoperation preventing device and the protection method can be applied to the field of transformer substations.

Description

technical field [0001] The invention relates to a split type anti-misoperation device. It belongs to the field of equipment protection devices. Background technique [0002] At present, the known arrangements of secondary measures in substations are all temporary measures, that is, they are covered by red curtains with the words "in operation" to distinguish the operating equipment from the maintenance equipment, so as to warn the maintenance operators There are two ways to fix it: one is to use magnets to absorb, and the other is to stick it with tape. The magnetic field will affect the microcomputer protection device in the control screen, and interference signals will appear, which will affect the reliability of power supply; second, when using tape to fix it, the work is time-consuming and laborious, and the firmness is not enough, and the "running" red curtain is prone to fall off This phenomenon makes the safety measures for substation maintenance operations imperfec...
