Description
Technical field
The utility model relates to the switchyard in power industry, is specially the switchyard of adapted multiple stage permanent-magnetic switching equipment.
Background technology
Permanent magnet mechanism is by realizing the repertoire of conventional switching devices mechanism by electromagnetic mechanism and permanent magnet special combination, and dropout that need not be traditional and locker can realize the maintenance function of mechanism's terminal location, better can mate vacuum interrupter combined floodgate characteristic again, and compact conformation, parts are few, it is convenient to control, autgmentability is strong, operate time, dispersiveness was little, be easy to the miniaturization and the intellectuality that realize switchgear, thus being subject to scientific research institutions and manufacturer's favor, is one of developing direction of Intellectualized Switchgear.
Although adapted permanent magnetic mechanism switch equipment is with the obvious advantage, through more than ten years development, its occupation rate of market deficiency of adapted permanent magnetic actuator vacuum switchgear joins 1% of the occupation rate of market of spring mechanism switchgear, returns its reason to mainly contain following 2 points.Reason one is that permanent magnet mechanism controller is positioned in switchgear framework on the spot, and it is complicated that switchgear test, operation and short circuit close process electromagnetic environment, causes controller to be subject to electromagnetic interference, affect its reliability.Reason two is permanent magnetic mechanism switch equipment along with its electric pressure improves, drop-out current increases, its action required merit enlarges markedly, thus cause capacitance to increase, course of action coil current increases, permanent magnetic controller is because it is by the restriction of permanent magnetic mechanism switch equipment installation dimension, powerful power electronic device can not be selected and in switchgear separating brake or feed motion process, do not allow power electronic device because of its overvoltage or overcurrent self-protection or shutoff, thus cause the difficult design of controller and less reliable, the overall performance affecting adapted permanent magnetic mechanism switch equipment improves.
Driving power (as the capacitor) life-span shortens with the rising of temperature.Secondly permanent magnetic mechanism switch equipment to cut-off capacity larger, then the capacitance needed for is larger, and volume is larger, and in switchgear, narrow space is unfavorable for the placement of capacitor and permanent magnetic controller.Again, the driving power capacity of permanent magnet mechanism is large, and the life-span is short, must change every 3-5.Change the capacitor in every platform switch cubicle, workload is large, and driving power voltage is beyond human safety voltage, if during switchgear maintenance, on electric capacity, electric energy does not exhaust, and may bring danger to operating personnel.
Because the existing permanent magnet mechanism driving power life-span is short, the manufacturer of permanent magnetic mechanism switch equipment wishes to adopt the direct current cabinet of transformer station to provide driving power for the permanent magnet mechanism in each switchgear.But the direct current cabinet of transformer station is mainly the electronic equipment such as station level, wall and provides stand-by power supply, and permanent magnet mechanism course of action institute energy requirement is larger, may cause direct current cabinet spread of voltage thus the normal work of influence process layer, wall electronic equipment, thus substation operation personnel do not allow permanent magnet mechanism to adopt direct current cabinet to drive.
And in prior art, the demand of technical standard transformer station of substation operation has a power failure after a period of time, the normal electric switch-on of permanent magnetic mechanism switch equipment energy, thus hand generator for subsequent use etc. is needed, but existing hand generator volume is larger and existing permanent-magnetic switching equipment does not have the electric of hand generator and mechanical interface, thus fails to be promoted use.
Utility model content

Preferably, the input of power panel connects the output of civil power or driving power.
Preferably, also hand generator is comprised; During switchyard power down, the output of hand generator is connected with driving power.
Preferably, communication board to be connected with superior system by optical fiber and to communicate.
Preferably, shielding cabinet adopts the secondary side device shielding cabinet of permanent-magnetic switching equipment.
Preferably, permanent magnet controlled making sheet adopts plate card type structure.
Compared with prior art, the utility model has following useful technique effect:
The utility model is by being separated the permanent magnet mechanism of permanent-magnetic switching equipment and control device, driving power and control board are carried out concentrated setting, and connected by cable after being separated by, not only increase the centralized and unified of its management control, improve the reliability of operation, and to the electromagnetic interference of driving power and permanent magnet controlled making sheet when avoiding permanent magnet mechanism action, thus the stability of powerful driving power can be met; After centralized management, follow-up maintenance and with change can carry out unifying repair inspection and change; Only adopt a set of power panel and charging module, significantly reduce cost; Permanent magnetic controller size is not by spatial limitation simultaneously, is easy to design.
Further, power panel can independently be powered to control board and communication board after connecting civil power, connects driving power in parallel simultaneously, can carry out unified power supply and export, extend live line work state when switchyard power down.
Further, by the hand generator arranged, only need connect once and just can all driving powers be charged, fast safe and convenient to use; And directly adopt the shielding cabinet of secondary side device, better can improve the reasonability of layout and the convenience of use.
