Description
Technical field
The utility model relates to a kind of outdoor vacuum electromagnetic load switch.
Background technology
The operating mechanism of outdoor vacuum load switch, common are two kinds, spring operating mechanism and electromagnetic mechanism.Electromagnetic mechanism wherein can provide the function of remote control port and automatic reclosing, and this is spring operating mechanism is incomparable advantage.Thus, along with the development that country is distribution network automated, state's electricity electrical network is more buying outdoor vacuum electromagnetic load switch.In existing outdoor vacuum electromagnetic load switch, control power supply is adopted to charge to large bulk capacitance, and using the power supply of bulky capacitor as solenoid, during due to mechanism action, enough large electric current is needed to produce electromagnetic force, in order to overcome the dead point of the State Transferring of transmission mechanism.Due to the stability of large bulk capacitance output current, when transmission mechanism completes combined floodgate, solenoid still adopts this big current to carry out the maintenance of on off state, gets off for a long time, will damage coil.
Summary of the invention
The purpose of this utility model is the defect overcoming prior art, provides a kind of separating brake and the combined floodgate that are realized switch by dual coil electromagnetic mechanism, without the need to large bulk capacitance, cost is low, volume is little, outdoor vacuum electromagnetic load switch that little power consumption, life-span are long.
For achieving the above object, the utility model adopts so a kind of outdoor vacuum electromagnetic load switch, comprise suspension holdfast, casing, be contained in the transmission mechanism in mechanism's cover, and be arranged at deciliter large handle and deciliter direction board that the outside of described mechanism cover and described transmission mechanism link, three-phase AC line is held in described casing, also electromagnetic mechanism is held in described mechanism's cover, described mechanism's cover lower end is provided with aviation socket, control line is caused the control end of described electromagnetic mechanism by described aviation socket, described electromagnetic mechanism comprises dynamic iron core, static iron core, and be arranged at hold-in winding and the actuating coil of described dynamic iron core and described static iron core periphery, push rod is through described static iron core, stretch in the hole of described dynamic iron core, described dynamic iron core acts on described transmission mechanism through described push rod.Compared with the prior art, the beneficial effects of the utility model are embodied in: by the setting of above structure, by controller through aviation socket, send the instruction of separating brake or combined floodgate to electromagnetic mechanism, and, when starting when closing a floodgate, actuating coil adhesive and then order about mechanism action; After feed motion completes, change and ensure that switch combined floodgate puts in place by hold-in winding adhesive; When after hold-in winding decompression, electromagnetic mechanism action realizes separating brake.The work whole process of on-load switch can be controlled by controller remote signalling, is easy to realize power distribution network intellectuality, and dual coil designs, greatly can reduce the volume of on-load switch, reduce the electricity loss of big current coil, extend the useful life of electromagnetic mechanism and product.
Especially, described transmission mechanism comprises head and the tail hinged support, connecting lever and spring, described support is articulated with the skeleton of described transmission mechanism by fixing point, and described support, under the cooperation of the push rod of described electromagnetic mechanism, rotates around described fixing point.By the setting of above structure, transmission mechanism is continuously harmonious with the meeting point that cooperates of electromagnetic mechanism, ensures that divide-shut brake having stable behavior is reliable.
Especially, the upper bottom surface of described casing is provided with air-filled pore, and the lower plane of described mechanism's cover is provided with steam vent.By the setting of above structure, can the operating mechanism of the high pressure three-phase AC line in the casing of on-load switch and mechanism's cover inside be sealed in insulating gas SF6, product non-oil ultra high vacuum system designs, high safety factor, and the orientation of air-filled pore and steam vent arranges the rule meeting gas flow, is convenient to the maintenance of product.
