Embodiment Construction

[0027] The technical solutions of the present invention will be further described in more detail below in conjunction with specific embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] refer to figure 2 , figure 2 It is a structural schematic diagram of a switchboard maintenance safety isolating device provided by the present invention. The device 100 includes a locking information module 110, a judging module 120, and an output module 130, which are used for maintenance and safety isolation of a switchboard 101 including two power supply incoming lines, two load outgoing lines, and a busbar ground knife.

[0029] The locking information module 110 is used to generate the locking in...

Abstract

The invention discloses a security isolation device for overhauling of a distribution board. The device comprises a locking information module, a judgement module and an output module, wherein the locking information module is used for generating locking information of the distribution board according to locking states of a power supply grounding knife-switch, a load grounding knife-switch and a bus grounding knife-switch; the judgement module is used for inputting locking information into preset logics and judging whether overhauling of the distribution board under the locking condition corresponding to the locking information is safe, and besides, the preset logics are the logics that no electric shock hazard exists during overhauling of the distribution board; the output module is usedfor outputting overhauling allowing information of the distribution board according to a judgement result of the judgement module, and besides, the overhauling allowing information is optical information and/or acoustic information. By means of the security isolation device, original complicated isolation locking operations without logic relations, which are managed through labels and locks, can be changed into computer automatic logic judgement, and the electric shock accident of people is thoroughly avoided. Besides, in the isolation operation process, the isolation progress can be seen froma display screen at any time, and workers can conveniently understand information.

Description

technical field [0001] The invention relates to the field of switchboard maintenance, in particular to a switchboard maintenance safety isolation device. Background technique [0002] In places where power systems such as substations and power plants require centralized control of a large number of power sources and loads, switchboards are widely used. The switchboard is shown in the figure below, mainly including bus bars and switches. Busbars are used to connect all the switches. The switch is used to control the on-off between the power supply and the load and the bus to achieve control. In order to ensure the safety of personnel when the switchboard is powered off for maintenance, a ground knife is installed on each incoming line, and a bus ground knife is set on the busbar. [0003] When the switchboard is overhauled during a power outage, safety measures must be artificially set to ensure the safety of the overhaul personnel. [0004] When a switchboard is powered ...
