Description
(1) technical field
The utility model relates to a kind of ac power electronic switch assembly.
(2) background technology
The development of producing along with modern industry also improves constantly the requirement of control system.Because traditional contact electrical equipment exists contact arching, melting welding and wearing and tearing and has inherent defect such as moving machinery parts, therefore usually can not satisfy control system about safe and reliable, frequent operation, long-life and high-precision requirement, various control system just constantly develop towards the direction that automation and oncontacting are revealed.
Ac power electronic switch is a kind of novel contactless forceful electric power electrical equipment that replaces the traditional electrical magnetic contactor that occurs after thyristor comes out, it mainly is made of bidirectional thyristor, owing to there is not moving component, so have that switching speed is fast, the life-span is long, power controlling is little and advantage such as sensitivity height.Simultaneously, because switching process always realizes when current over-zero, so the inductance accumulation of energy that exists in load circuit or the power circuit can not cause electric arc and overvoltage.Because every half cycle can both " self-locking ", so there is not the problem of " contact bounce ".But its superiority is especially remarkable under hard work conditions such as frequent inverse conversion.
Though ac power electronic switch is compared with A.C. contactor and is truly had plurality of advantages, also there are many defectives from present domestic each industrial and mining enterprises' existing equipment, now be analyzed as follows:
1, present, ac power electronic switch all is mounted in the electrical control cabinet, and because of bulky, occupied ground is bigger, is not easy to expand multimachine control, and simultaneously, the ac power electronic switch parts are dispersed in each position in the rack, so the integral protection poor performance.
2, the signal controlling end of bidirectional thyristor is longer with triggering controller on line, exists the job insecurity factor.On line is also longer between the protector of bidirectional thyristor and the thyristor, and the protection reliability is relatively poor.
3, because, master switch is to adopt the bidirectional thyristor device, is main heat generating components in the rack, so all be to adopt the heat radiation of enclosure top integrated air exhaust basically, causes in the rack each parts laying dust bigger thus, dust is difficult to removing in the rack.Simultaneously, because of the variation of weather, humidity also often changes in the rack, long-term use, and the components and parts in the rack cause electric insulation in various degree to descend, and make in the rack and constantly break down, so can not work steadily in the long term, maintenance work has high input.
If 4 electrical control cabinets are operated in the band corrosive gas environment, make each components and parts seriously corroded in the machine and can't long-term work, thereby the ac power electronic switch cabinet is damaged in advance, even scrap.
(3) utility model content
The purpose of this utility model provides and is a kind ofly reducing the ac power electronic switch assembly that the integrally-built while can have good heat radiation function again.
For reaching above-mentioned purpose, ac power electronic switch assembly of the present utility model, comprise a base chassis, be provided with circuit controller in the described base chassis, the tank surface of described base chassis is provided with signal input part binding post, zero line side binding post and earth terminal binding post, described each binding post links to each other with described circuit controller, it is characterized in that: be installed with two on the described base chassis respectively with the radiator of busbar, the inner face of described two radiators is embedded a thyristor planar chip and combines fixing by connector; On described two radiators that combine, be installed with axial flow blower by the insulation of angle Support support; Described circuit controller links to each other by the control end of control line with described thyristor planar chip.
Adopt such structure, because the master switch parts of electronic switch assembly and being combined into one of circuit controller, make its compact conformation, volume little, aesthetic in appearance, and saved installing space, but minimizing wiring Fast Installation.With the thyristor planar chip is the master switch parts of main devices, press fixing with two radiators respectively at two end face, making the thyristor planar chip directly to dispel the heat, so the radiating effect spy is good, also is a kind of of the best in the present semiconductor device radiating mode.And parts such as circuit controller and circuit brake all are sealed in the metab cabinet of band anticorrosive coat, reach dustproof, moistureproof, anticorrosion veritably, prevent effect such as signal interference.Electronic switch assembly is durable in use, and the reliability height is non-maintaining.
For further specifying above-mentioned purpose of the present utility model, design feature and effect, the utility model is described in detail below with reference to accompanying drawing.
