Abstract
A kind of can effective arc extinguishing and prevent from going here and there the PC level double power supply automatic transfer switch of arc, described switch is provided with arc-chutes, described arc quenching chamber structure is a rectangular box removing arranged on left and right sides panel, in the front and back panels of rectangular box, symmetrically be fixed with acclivitous polylith electric arc corbel back slab, it is characterized in that: the front and back panels foot in described arc-chutes, be arranged with in case and extend and leave the heat-resistant fireproof organic insulation electric arc baffle plate of spacing.The utility model increases standing electric arc baffle plate on PC level double power supply automatic transfer switch arc-chutes, this baffle plate uses the organic insulation of heat-resistant fireproof, be designed to special shape, be fixed on bottom arc-chutes, between standing contact, the product standing contact that realizes truly is isolated, while improving product joint weldment ability, more reliable in operational safety performance.
Description
Technical field
The utility model relates to a kind of double power supply automatic transfer switch, especially relate to a kind of can effective arc extinguishing and prevent from going here and there the PC level double power supply automatic transfer switch of arc.
Background technology
At present, the double power supply automatic transfer switch of industry production especially PC level double power supply automatic transfer switch is all provided with arc-chutes, arc quenching chamber structure is a rectangular box removing arranged on left and right sides panel, in the front and back panels of rectangular box, symmetrically be fixed with acclivitous polylith electric arc corbel back slab, so that electric arc when being separated by the moving contact be fixed in switch case outside the office arc-chutes left and right sides or closing a floodgate is guided into knock out.
This PC level double power supply automatic transfer switch is in the production-type test carried out according to national standard or onsite application, bringing onto load conversion can be carried out when the Short-Circuit High Current of generation 6 times or 10 times nominal loads, now due to product its structural design problem, cause when switching between conventional and stand-by power supply, occur that breaking arc and combined floodgate electric arc, from the bottom of arc-chutes, arc phenomenon occurs to go here and there, finally cause conventional and the direct conducting of stand-by power supply or phase fault scaling loss, unsafe factor is caused to operational outfit and building, there is very large potential safety hazard.
Utility model content
Technical problem to be solved in the utility model, just be to provide a kind of can effective arc extinguishing and prevent from going here and there the PC level double power supply automatic transfer switch of arc, when load end produces big current, the electric arc that product normal stand-by power supply dynamic/static contact deciliter moment produces can be extinguished instantaneously, and very effectively can stop the string arc phenomenon between conventional stand-by power supply, make its reach conventional for subsequent use between the real isolation of electric arc.
Solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of can effective arc extinguishing and prevent from going here and there the PC level double power supply automatic transfer switch of arc, described switch is provided with arc-chutes, described arc quenching chamber structure is a rectangular box removing arranged on left and right sides panel, in the front and back panels of rectangular box, symmetrically be fixed with acclivitous polylith electric arc corbel back slab, it is characterized in that: the front and back panels foot in described arc-chutes, be arranged with in case and extend and leave the heat-resistant fireproof organic insulation electric arc baffle plate of spacing.
The outer end of described symmetrical electric arc baffle plate is inserted in the mounting groove of front and back panels foot, inner end is arranged on draw-in groove.(after having the first bending deformation of certain flexible electric arc baffle plate, assembling will snap in draw-in groove)
Beneficial effect: the utility model increases standing electric arc baffle plate on PC level double power supply automatic transfer switch arc-chutes, this baffle plate uses the organic insulation of heat-resistant fireproof, be designed to special shape, be fixed on bottom arc-chutes, between standing contact, the product standing contact that realizes truly is isolated, while improving product joint weldment ability, more reliable in operational safety performance.
This switching device by this scheme carry out manufacturing and designing on probation after works very well, device is all successfully completed normal conversion by national standard after repeatedly large multiple rated current test, successfully solves the arc extinguishing problem for many years perplexed.

Detailed description of the invention
See Fig. 1 to Fig. 4, of the present utility model can effective arc extinguishing and prevent from going here and there the PC level double power supply automatic transfer switch embodiment of arc, switch is provided with arc-chutes 1, arc quenching chamber structure is a rectangular box removing arranged on left and right sides panel, in the front and back panels of rectangular box, symmetrically be fixed with acclivitous polylith electric arc corbel back slab, the front and back panels foot in arc-chutes, be arranged with in case and extend and leave the heat-resistant fireproof organic insulation electric arc baffle plate 4 of spacing; The outer end of symmetrical electric arc baffle plate is inserted in the mounting groove 2 of front and back panels foot, inner end is arranged on draw-in groove 3.
See Fig. 5, moving contact 5, static contact 6 are arranged on change-over switch housing, arc-chutes are arranged between two moving contacts and locate, after installation, whole housing is a pole of BYES9 double power supply automatic transfer switch, in double power supply automatic transfer switch normally uses, rotating shaft is driven to make conventional by conversion operations mechanism or moving contact 5 for subsequent use presses down or pull-up to contact with static contact 6 to be formed and to close a floodgate or separating brake connects disjunction.
Arc extinguishing procedure declaration: with conventional power supply for main power source is preferential, when there is Short-Circuit High Current fault in the line, double power supply automatic transfer switch is transformed into stand-by power supply automatically by commonly using power supply, contact for subsequent use connection process time is disconnected to very short from conventional contact, General Requirements is between 50-200ms, as arc extinguishing within the short time like this, arc performance is bad, short circuit between normal stand-by power supply will be caused, namely conventional power contact head disconnects the electric arc produced instantaneously, need extinguish before stand-by power supply contact is connected or effectively isolate, namely bottom arc-chutes, the organic insulation electric arc baffle plate of two pieces of heat-resistant fireproofs is installed herein additional to intercept the string arc between normal stand-by power supply, the electric arc allowing contact disjunction produce has time enough to be extinguished by arc extinguishing grid pieces cutting, arrive real isolation arc quenching effect.
Note: be not limited to this model of BYES9 with the matching used automatic change-over of the utility model.
