Description
Technical field
The present invention relates to isolator operation control technology in power system, more particularly to breaker both sides disconnecting switch
Operation power intelligence feeding device.
Background technology
When interruption maintenance work is met, Substation Operating personnel will in advance prepare grid switching operation to Substation Electric Equipment
Ticket.Grid switching operation bill is related to some to be spaced or a line outage or power transmission work（One grid switching operation bill can only fill in one
Individual operation task）, electrical equipment power failure operation comprising equipment by operation turn it is standby, power transmission operation comprising equipment by alternate transport
OK.
Two disconnecting switch of one electrical separation comprising a primary cut-out and primary cut-out both sides（Load side every
Leave pass, mains side disconnecting switch）, it is by order on grid switching operation bill when meeting isolator operation by Substation Operating personnel
Operate item by item, the operation power of disconnecting switch of first being closed before certain the side disconnecting switch for operating primary cut-out is broken again after operation
Open the operation power of the disconnecting switch.If this spacing devices normally runs, interval switch both sides knife isolator operation
Power supply all in input position, can bring hidden trouble to power grid security, reliability service.
Transforming plant primary electrical equipment operation is to realize remote operation with vulnerabilities scan forceful electric power, and the vulnerabilities scan of transformer station is high
Spend integrated, Microcomputer.
Separating brake, the closing circuit of transforming plant primary electrical equipment control loop are all gone here and there the contact of vulnerabilities scan, uses these
Contact comes the separating brake and closing operation loop of electrical equipment of distant place control.
The operating mechanism box of disconnecting switch lacks effectively protection out of doors throughout the year, if electric equipment element using parameter and
Running environment is undesirable, and control loop light current contact has the situation of adhesion and DC earthing, if disconnecting switch simultaneously
It is out of control that operation power will result in disconnecting switch in input position, easily causes power grid accident.
Isolator operating mechanism：It is made up of motor-driven loop, control loop, the part of subsidiary loop three.
Isolating switch mechanism operating principle：It is by control loop control separating brake, the closing contactor, contactor of disconnecting switch
Isolating switch motor driving circuit is connected in powered adhesive, and motor realizes the separating brake of disconnecting switch, closing operation with electric operation.
Motor-driven ring current is exactly the isolator operation power supply of operating personnel's disconnecting switch operation, disconnecting switch
Operation power is put into advance by operating personnel before disconnecting switch operation（Prevent that operating personnel from touching by mistake or device interior failure is made
It is out of control into disconnecting switch）Isolator operation terminates rear opening operation power supply.
Power system isolator operation is sequentially：Power failure operation-first disconnects primary cut-out-pull open load side isolation
Switch-pull open mains side disconnecting switch, power transmission operate-checks that primary cut-out is located at off-state-push to mains side isolation
Switch-push to that load side disconnecting switch-close primary cut-out.
The actual electrical equipment power cut isolating switch operation in scene：After being disconnected by an electrical equipment primary cut-out, operation
Personnel operate item by item according to content on operation order, load side of closing first isolator operation power supply, then are supervised by control room backstage
Control machine, the control loop of disconnecting switch operation realizes that the sub-switching operation of disconnecting switch, the sub-switching operation of disconnecting switch break after terminating
Open load side isolator operation power supply.Followed by mains side disconnecting switch is similarly.
Example：Power train unifies the switch gap power failure operations of seat 220kV transformer station 220kV 220, in the isolation of the east of operation 220
During switch, operating personnel just closed 220 eastern isolator operation power supply while 220 eastern isolating switch motors band electric operations,
220 eastern disconnecting switch just complete sub-switching operation in the case of the control loop without disconnecting switch operation, and disconnecting switch occurs
State out of control.Control loop DC earthing is found out in ex-post analysis, causes the improper connection-control of contact of vulnerabilities scan
The normal opened contact adhesive of the powered rear contactor of loop separating brake contactor coil, motor leads to after operating personnel put into operation power
Electric operation.Because isolator operation power supply neither one reliability input scheme causes disconnecting link out of control in current operation.Luckily
To be operating personnel perform in strict accordance with operational procedure, safety code, do not cause casualties and power grid accident.
Also in isolator operation, artificial operation requirement is concentrated, and a large operation needs two hours even
Longer, operating personnel's energy is limited.It is electric that fatigue operation consequence can cause to be gone to the wrong way during human users interval, isolator operation of miscarrying
Source, has above-mentioned proof to go to the wrong way and is spaced the cost that isolator operation power supply of miscarrying is possible to pay blood.Although transformer station has anti-
Misoperation system, measure and control device have electric blocking, but human casualty accident still takes place frequently in power system isolator operation.
