Abstract
The utility model discloses the explosion-proof electric power capacitor combination of a kind of filtering type intelligent low-pressure magnetic latching relay, in this electric capacitor combination, need three adjacent installations side by side of magnetic latching relay, magnetic latching relay is built in shell and is formed by magnetic latching relay, and described shell is provided with two groups of wind holes.Two groups of wind pore size distributions are in the both sides of shell, and one-tenth is dislocatedly distributed.Thisly be conducive to avoid arc light cross influence while being distributed in the actuating of relay, prevent damage relay itself being brought by arc short-circuit.
Description
Technical field
The utility model relates to the explosion-proof electric power capacitor combination of a kind of filtering type intelligent low-pressure magnetic latching relay.
Background technology
About the explosion-proof electric power capacitor combination of filtering type intelligent low-pressure magnetic latching relay, the explosion-proof electric power capacitor combination of this filtering type intelligent low-pressure amounts to needs three magnetic latching relays, three adjacent installations side by side of relay, and prior art is:
1) magnetic latching relay is built in shell and forms, and has two symmetrical wind holes on shell.
2) magnetic latching relay is built in shell and forms, and on the magnetic latching relay in the middle of being contained in, has two symmetrical wind holes, and be contained on the relay on both sides, only has the wind hole in an outside to use, and another one wind hole is insulated plate and seals.
The weak point that above technology exists is: the combination of filtering type intelligently realizing explosion-proof electric capacitor needs three adjacent installations side by side of magnetic latching relay, the arc light producing when magnetic latching relay is worked can produce arclight, arclight can outwards be launched by wind hole, because the wind hole of magnetic latching relay is to be arranged symmetrically with, therefore the arclight that adjacent relay emits can interact, make the possibility of this filtering type intelligently realizing explosion-proof electric capacitor combination results short circuit, and then have very fearful harm; If the wind hole of a close side is sealed, the arclight that can make magnetic latching relay produce can not fully distribute, and heat can not scatter and disappear smoothly, long-term like this, can affect the useful life of magnetic latching relay, adds the cost of large enterprises.
Summary of the invention
The purpose of this utility model: a kind of method that solves the harm that magnetic latching relay arclight brings is provided.
The utility model is the explosion-proof electric power capacitor combination of a kind of filtering type intelligent low-pressure magnetic latching relay, by magnetic latching relay, be built in shell and form, on described shell, there are two groups of wind holes, wind hole is located at the both sides of magnetic latching relay, and its innovative point is: described wind hole is located on adjacent relay face in opposite directions; Described wind hole becomes dislocation to arrange.
On this basis: described wind hole is the dislocation of height direction; Described wind hole stagger distance be 2 ~ 10mm.
On this basis: distance is staggered for 5mm in described wind hole.
The beneficial effects of the utility model are:
By the dislocation of the wind hole of magnetic latching relay shell is arranged, when this distribution can be avoided adjacent magnetic latching relay action, the arc light of radiation influences each other, reduced this operation of shutoff wind hole, solved the infringement that short circuit or heat by system can not scatter and disappear equipment itself is brought very soon, extend the useful life of equipment, saved the production cost of enterprise.
Below coordinate accompanying drawing to describe in detail.

Fig. 2: magnetic latching relay shell wind hole site right view
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 1 and Figure 2, the wind hole of described magnetic latching relay shell both sides is respectively 1-1 and 1-2, from scheming, can find out that the wind hole of both sides is for being in staggered distribution, so just avoided influencing each other of arclight between two adjacent relays, avoid the harm of system short-circuit, extended the useful life of magnetic latching relay.
