Problems solved by technology

The frequent accidents of accidentally entering the live compartment indicate that the existing anti-misoperation locking device of the high-voltage switchgear cannot guarantee the operation safety to a certain extent, and even has fatal safety hazards. Therefore, the equipment needs to be further improved. When approaching live equipment, it is an urgent problem to be solved to effectively remind the staff and the surrounding personnel to operate safely and standardizedly.

Embodiment 1

[0032] Such as figure 1 As shown, a live switch cabinet interval anti-mis-entry device, the anti-mis-entry device mainly includes a signal module 1, a power module 2, an early warning module 3 and a notification module 4, wherein:

[0033] Described signal module 1 mainly comprises signal acquisition module 5 and signal processing module 6, and signal acquisition module 5 is a high-voltage charged display device sensor, and whether electrification is collected to live switch cabinet interval; Signal processing module 6 comprises rectifier bridge, relay, light Coupler and piezoresistor to transmit and judge the information collected by the signal acquisition module;

[0034] The early warning module 3 mainly includes a sensor and an acousto-optic warning light, which collects and feeds back information on the behavior of personnel entering the electrified interval by mistake, and warns the operator through the acousto-optic warning light;

[0035] The notification module 4 ma...

Embodiment 2

[0038] Such as Figure 1-3 As shown, an anti-mis-entry device for the interval of a live switch cabinet, the anti-mis-entry device is an integrated structure, and its shell is provided with a buckle that can be directly stuck on the back strip of the switch cabinet, and can be directly stuck on the switch cabinet. Just put it on the back strip of the cabinet, no need to open holes for fixing. Easy to install and save space.

Abstract

The invention relates to the technical field of a high voltage switchgear, and especially to a live-line switchgear partition anti-straying device. The anti-straying device is an integrated structure and mainly comprises a signal module, a power supply module, an early warning module, and a notification module. The invention designs and develops the live-line switchgear partition anti-straying device which obviously distinguishes a live-line device partition from a neutral device partition, and gives out a live-line prompt for construction personnel. When the relevant personnel stray into the live-line partition and perform illegal operation, the device will give out obvious and effective acousto-optic alarms at the earliest time and inform the peccary personnel of stopping of the operation. The alarms and the illegal information are sent to related work personnel in charge, and the strict supervision of the live-line operation is realized. The illegal operation can be effectively prevented, that is when the operators of the high voltage switchgear stray into the live-line partition, a misoperation-preventive locking device installed on the high voltage switchgear can timely send obvious alarm signals, thereby effectively reducing the accident incidence rate.

Description

technical field [0001] The invention relates to the technical field of high-voltage switch cabinets, in particular to a device for preventing misentry at intervals of live switch cabinets. Background technique [0002] At present, the high-voltage switchgear of the substation contains various electric equipment and instruments, which are widely used. Due to the different operating states of the equipment, the internal power environment is extremely complicated. Therefore, the anti-misoperation locking device on the high-voltage switchgear to prevent accidental entry into the live compartment is very important, and it is directly related to the personal safety of the operator. [0003] According to the statistics of the State Grid Corporation of China's safety accident reports in the past two years, most of the accidents that strayed into the electrified interval caused the fatal accident of the staff. Most of the accidents are due to the fact that the staff did not correct...
