Abstract

An earth wire hanging, demolishing and management system is used for a power plant and a substation. The management is characterized in that a main control management platform is arranged in a commandmaster-control room, and a secondary reexamination system is established for giving order of the demolishment of the earth wire, terminal operation and dismounting the earth wire to return the main control; a main control management program implements the earth wire hanging, demolishing and management system by a host simulating operation screen. The hard ware setting relates to that the earth wire combines with a tracker to be a signaling terminal; a troubleshooter carries out an order to the order target of an earth wire pile hanging tracker; the tracker keeps wired communication with the management system and displays position occupied; if errors are found when the demolished tracker carries out identifier reexamination at the main control platform, an audio alert works and full records are left in the main control program, therefore, the system realizes real-time communication with the dispatching of a higher authority and the local control. The management system constitutes two-level reexamination of the troubleshooter and a commander so as to ensure the correct hanging and demolishing of the earth wire and to avoid incorrect order manipulation accident; the system has the advantages of remarkable low cost and is a precautionary measure on work safety, which is easy and simple to implement in the present power sector.

Description

The earth lead suspension dismounting management devices

Technical field

The present invention relates to the maintenance and management of electric power facility, a kind of earth lead suspension dismounting management devices.

Background technology

Earth connection also is ground connection envelope line, and earth connection mainly uses in water generating factory, thermal power plant, cogeneration power plant, various grade transformer station.Induced voltage and repair apparatus residual charge for unexpected incoming call of the power failure equipments that prevents from just overhauling or generation when the electrical production repair apparatus damage the maintainer, and the three phase mains of repair apparatus input is taked the facility of short circuit ground connection.Earth connection is the important measures of protection maintainer safety, also is the important step in the grid switching operation process.Along with economic development, the power load sharp increase, the maintenance task progressively increases, and the earth connection frequency of utilization increases, and thing followed misoperation fault also increases relatively.So far, electric power system lacks effectively management in the ground connection operating process, still adopt storehouse to deposit labelled ground wire and connect end, ground wire outbound and use information spinner will lean on the operating personnel of each side such as commander, depositary management and maintenance to transmit, lack real-time monitoring, management means is relatively backward, and the misoperation probability increases relatively.80% all is that the commander personnel do not have in time to verify whether ground wire removes the misoperation that finishes and cause in the switching on earth wire accident.Each accident all brings huge injury and damage for maintainer and power equipment.

Summary of the invention

The purpose of this invention is to provide a kind of earth lead suspension dismounting management devices, the ground wire after operational order and the dismounting is put on record by the management system record, thereby stopped the wrong report accident whether ground wire is removed.

A kind of earth lead suspension dismounting management devices, be used for power plant, transformer station, it is characterized in that master control management platform working machine being set at commander's master-control room, built-in dismounting ground wire instruction issuing, terminal job, pull down the master control hypervisor that secondary that ground wire returns master control is rechecked system, the master control hypervisor is implemented the job management of ground wire suspension dismounting by main frame simulated operation screen; Terminal is provided with: ground wire and tracker are combined into the Signal Terminal of management devices, and tracker and this master control management platform keep wire communication, when hanging tracker in the stake of instruction target ground wire, show occupy-place; The tracker of dismounting is carried out finding that mistake has audio alert when identification code is rechecked, and in the master control hypervisor, stays full record that management devices is also realized real-time communication with higher level's scheduling, local control in this master control management platform.

What analyze the switching on earth wire accident cause is that management mode is single: be that alternative order is assigned execution again between commander and the builder, the device after ground wire being removed is reviewed, thereby the feedback information appearance whether " dismounting ground wire " instruction is finished is misinformated.And management devices of the present invention is set up ground wire hardware management platform at commander's master-control room, the ground of dismounting line record is arranged in the system behind the instruction issuing, maintenance is finished the tracker of taking back ground wire and check single-minded tracker identification code on management platform, form the management system that maintenance builder and commander's two-stage are reviewed, standard and constraint operating personnel behavior, therefore can guarantee that ground wire correctly hangs and removes, avoid taking place the instruction misoperation fault.This device has significant low-cost advantage, is the present safety in production precautionary measures simple in power industry.
