Abstract
The invention discloses a substation temporary ground unlocking-locking control system comprising a temporary ground master and ground wire locks. The temporary ground master is connected with at least one ground wire lock through a communication bus. Each ground wire lock corresponds to one ground wire. The temporary ground master is connected with a five-prevention master which is connected with a monitoring master. Each ground wire lock is provided with a code reader and a locking mechanism. The substation temporary ground unlocking-locking control system has the advantages that the ground wires can communicate with the substation five-prevention master and background, the process of mounting and demounting the ground wires during line operation is standardized by technological means, potential serious accidents caused by human factors are eliminated, and security operation of power equipment and safety of personnel are reliably guaranteed.
Description
technical field:
The present invention relates to a kind of transformer station maintenance system, particularly relate to a kind of transformer station temporary grounding open locking control system.
background technology:
Essential a kind of safety appliance when temporary ground wire is the work of electric wiring or equipment interruption maintenance, for guaranteeing operations staff's personal safety; Whether in five-prevention operation, have the regulation that prevents live connection of ground wire, prevents from closing with ground wire disconnecting link, therefore installing and removing earth connection is correctly that transformer station avoids occurring an important process in pernicious misoperation fault work.In practical operation, the action need of earth connection judges judge whether earth connection has departed from electric main equipment artificially, and mistake occurs thus hangs to tear open, leak and hang the pernicious misoperation event such as tear open, makes earth connection become great misoperation hidden danger.Micro_computer five_proof system is for avoiding artificial electric fault-operation accident to play an important role, but current five-preventing system can't solve the dismounting problem of temporary ground wire.
summary of the invention:
Technical problem to be solved by this invention is: overcome the deficiencies in the prior art, a kind of reasonable in design, precise control is provided and reduces transformer station's temporary grounding open locking control system of human accident.
Technical scheme of the present invention is: a kind of transformer station temporary grounding open locking control system, contain temporary grounding main frame and earth connection dead lock, described temporary grounding main frame interconnects by communication bus and at least one earth connection dead lock, described in each, earth connection dead lock is corresponding with an earth connection respectively, described temporary grounding main frame and five anti-main frames interconnect, and described five anti-main frames and monitoring host computer interconnect.
Described five anti-main frames and monitoring host computer interconnect by data communication network and data center respectively.Described communication bus is RS485 bus, between described five anti-main frames and temporary grounding main frame, adopts Ethernet, RS485 and RS232 communication mode to interconnect.On described earth connection dead lock, code reader and blocking mechanism are installed.Described earth connection is all fixed on corresponding ground clamp, and described temporary grounding main frame is connected with alarm.
The invention has the beneficial effects as follows:
1, the present invention is grounded the anti-machine of Xian Yu transformer station five and background communication, by technological means standard in line work, hang, the flow process of dismounting ground wire, eliminated the hidden danger that human factor causes serious accident, for safe operation and the personal security of power equipment provides reliable guarantee.
2, temporary grounding main frame of the present invention adopt microprocessor complete to the control of each earth connection dead lock and with the communicating by letter of five anti-main frames, and adopt RS485 communication mode to complete and the information interaction of each temporary ground wire dead lock of disperseing to install.Solved the problem of substation field installation requirement long haul communication, also realized the control of a main frame to a plurality of earth connection dead locks, native system has not only supplemented the function of five-prevention operation, and is convenient to maintenance management, and can effectively analyze and add up all kinds of operation informations.
3, the present invention is when ground wire is suspended in the screens of earth connection dead lock appointment, and detecting locking can identity value, thus identification ground wire can be by correct ground wire locking.After five anti-host authorizations, can be by the ground wire locking of also returning or by the ground wire release of locking, thus realize locking and the release of ground wire.
4, reasonable in design, the precise control of the present invention and reduce human accident, it is applied widely, is easy to promotion and implementation, has good economic benefit.
accompanying drawing explanation:
The circuit theory diagrams of Tu1Wei transformer station temporary grounding open locking control system.
embodiment:
Embodiment: referring to Fig. 1, in figure, 1-earth connection, 2-earth connection dead lock, 3-communication bus, 4-temporary grounding main frame, 5-data center, the anti-main frame of 6-five, 7-data communication network, 8-monitoring host computer.
Transformer station's temporary grounding open locking control system contains temporary grounding main frame 4 and earth connection dead lock 2, wherein: temporary grounding main frame 4 interconnects by communication bus 3 and at least one earth connection dead lock 2, each earth connection dead lock 2 is corresponding with an earth connection 1 respectively, temporary grounding main frame 4 and five anti-main frames 6 interconnect, and five anti-main frames 6 interconnect with monitoring host computer 8.
Five anti-main frames 6 and monitoring host computer 8 interconnect with data center 5 by data communication network 7 respectively.Communication bus 3 is RS485 bus, between five anti-main frames 6 and temporary grounding main frame 4, adopts Ethernet, RS485 and RS232 communication mode to interconnect.
Code reader and blocking mechanism are installed on earth connection dead lock 2.Earth connection is all fixed on corresponding ground clamp, and temporary grounding main frame 4 is connected with alarm.
Five anti-main frames 6 adopt the industrial computer of standard and share with five-preventing system.Earth connection 1 is all fixed on corresponding ground clamp, owing on each earth connection dead lock 2, code reader and blocking mechanism being installed, when the ground clamp of dead earth line mounts the appointment screens of earth connection dead lock 2, code reader will monitor location status, will be kept at local cache.Unified each earth connection dead lock 2 of controlling of temporary grounding main frame 4, by cyclic query state of earth wire and earth connection code value in place, judges whether earth connection is placed correctly, and by correct earth connection locking.After five anti-main frames 6 are authorized, can be by the earth connection locking of also returning or by the ground wire release of locking, thus realize locking and the unlocking function of ground wire.
