Description
Technical field
The present invention relates to a kind of contactor, particularly a kind of contactor that need on the lateral surface of its base element, leave the preformed hole that is used for peripheral hardware auxiliary contact, mechanical interlock or other auxiliary unit.
Background technology
In existing contactor, on at least one lateral surface of its base element, be provided with the through hole that at least one is used for peripheral hardware auxiliary contact, mechanical interlock or other peripheral hardware servicing unit, and these through holes are to be used for the parts of base element inside are realized being connected or contacting necessary passage with the parts of the auxiliary unit of base element outside, and manufacturing firm is often reserved when making base element.Along with the development of contactor product, need the increasing peripheral hardware auxiliary unit of configuration, so the preformed hole on the base element lateral surface also is on the increase thereupon.And when reality was used, owing to not using the not congruent reason of peripheral hardware auxiliary unit or auxiliary unit peripheral hardware, these penetrating unlimited preformed holes usually were in exposed state.
The reason that preformed hole exposes appears, the situation that also may come from the composite type base unit, that is: the base unit of a multipole contactor is made up of a plurality of one poles or multipole base element, in order to realize being connected or contact of parts between the utmost point and the utmost point, need on the outer side edges of base element, reserve through hole.After a plurality of one poles or multipole base element were assembled into base unit, the reservation through hole on the lateral surface of its outermost base element can all be in exposed state.
As everyone knows, dust and moisture are very harmful for the safety of electric product and life-span, and contactor is no exception, if its dustproof and moistureproof system is destroyed, then dust and moisture will accelerate to corrode the parts in the contactor, cause malfunctioning, the inefficacy of contactor product; Enter in the contactor if any bulky grain dust or water droplet, also can cause the utmost point in the contactor and the short circuit of interpolar, thus personal safety accident such as explosion caused.
Find through a large amount of contrast tests: the arc erosion vestige that does not have in the contactor test specimen that exposes preformed hole on the shell concentrates in striking district, arc-chute and the arc channel of contactor, and the arc erosion vestige on the parts beyond striking district, arc-chute and the arc channel is less, thereby proof electric arc moves towards to arrive the striking district along design, cut apart, cool off, extinguish by arc-chute, and gas is discharged via arc channel.Yet, it is not the striking district that only concentrates on contactor that arc erosion vestige in the contactor test specimen that exposes preformed hole is arranged on the shell, in arc-chute and the arc channel, the striking district, also there is more serious arc erosion vestige on the parts beyond arc-chute and the arc channel, and the striking district, the ablation vestige then weakens relatively in the arc-chute, thereby proof electric arc does not carry out along the trend of design, wherein some electric arc has changed trend, ablated parts beyond the striking district, and these parts are to be made by the material of not anti-ablation, so, at the trial, the test specimen with penetrating preformed hole will cause following phenomenon:
1, causes having the arc short circuit phenomenon between the phase and phase of contactor test specimen or single-phase and the electromagnetic system.
2, do not cut apart, cool off, extinguish via arc-chute fully owing to electric arc, but burning between each phase, so when test reached certain number of times, parts were burnt by electric arc between phase and phase, test specimen is blasted.
3, since electric arc do not carry out along trends of design fully, the contact of seriously ablating, phenomenon such as the contact adhesion may occur, come off greatly reduces useful life of contact.
As everyone knows, when electric arc produces, its ambient air is expanded rapidly, so inside and outside the pedestal of contactor, form draught head.When the arc quenching system of design contactor, the capital utilizes air flow path of this draught head design, utilize this draught head to promote electric arc and enter striking district, arc-chute along the path of designing, electric arc is cooled, cuts apart, extinguishes behind striking district, the grid grid that go out, and gas is discharged by arc channel.Because the existence of the preformed hole that exposes has changed intrinsic air flow path, under the effect of described draught head, electric arc is changed move towards to scurry out the striking district, the parts beyond the ablation striking district.
Above-mentioned preformed hole does not cause people's attention so far as yet for the phenomenon that changes the electric arc trend.So the contactor product of prior art is not taked effective plug-hole measure to preformed holes a large amount of on the shell so far, the example of the mode plug-hole of the useful self-adhesive paper stickup of idol at present.Yet, owing to do not consider that the inside and outside draught head of the caused pedestal of electric arc to problems such as the impulsive force of plug-hole element and the caused thermal effects of electric arc, makes self-adhesive paper break very soon, do not glue, peel off, lose efficacy.And self-adhesive paper itself is moisture-proof not, and is not fire-resistant, so use the self-adhesive paper plug-hole to have great reliability and security hidden danger, also can not solve the defective of above-mentioned prior art at all.
