Abstract
The utility model discloses a kind of novel disconnecting link type twin-power switch, comprising insulator foot, the insulation movement arm that can move in parallel along insulator foot, be fixed on the fixed contact on insulator foot and be fixed on insulation movement arm both sides can with two moving contact of insulation movement arm translation, accordingly, fixed contact on the insulator foot of the insulation upper and lower both sides of movement arm respectively establishes one, distance during gate-dividing state between moving contact and fixed contact.Distance between the utility model moving contact and fixed contact, can work as isolation fracture, and arc extinguishing ability is strong, and electric arc easily extinguishes; Possess two fractures, extinguish arcs easier than fracture, in addition, proof voltage impact capacity is also stronger.
Description
Technical field
The utility model relates to twin-power switch, is specifically related to a kind of novel disconnecting link type twin-power switch.
Background technology
Duplicate supply refers to a kind of by Microprocessor S3C44B0X, starts the device switched, power supply can be made to power continuously for electrical network in network system and electrical network or electrical network and generator power supply.As executive component, be equipped with automatic controller and band machinery and the chain controlling organization of electrical interlocks that single-chip microcomputer is core, be a kind of perfect performance, safe and reliable, automaticity is high, electric elements that the scope of application is wide.
Twin-power switch is when normally working, switch connection is on main power circuit, when because the power failures such as the unexpected phase shortage of outside cause, under-voltage, overvoltage time, switch then can be switched to rapidly on stand-by power supply circuit timely, make important machinery equipment can not continue normally to carry out work by the impact of power-off, avoid due to unexpected power-off and machinery equipment is quit work.Current double power supply converting switch is owing to moving contact can produce oxide layer after use a period of time, and causing trouble rate is higher; In addition, arc extinguishing ability and proof voltage impact capacity are not by force defects of current double power supply converting switch yet.
Utility model content
The utility model mainly provides that a kind of self-cleaning function is better, arc extinguishing ability and the strong double power supply converting switch of proof voltage impact capacity.
The utility model solves the technical scheme that its technical problem adopts: a kind of novel disconnecting link type twin-power switch, comprise insulator foot, the insulation movement arm that can move in parallel along insulator foot, being fixed on the fixed contact on insulator foot and being fixed on can with the moving contact of insulation movement arm translation on insulation movement arm, described moving contact is respectively equipped with one in the insulation upper and lower both sides of movement arm, and the fixed contact be fixed on insulator foot is also respectively equipped with one in the insulation upper and lower both sides of movement arm.
As the further improvement of a kind of novel disconnecting link type twin-power switch of the utility model, fixed contact and moving contact are 0 ~ 26.3 mm when twin-power switch gate-dividing state in the distance on movement arm translation direction that insulate.
The beneficial effects of the utility model: adopt disconnecting link type parallel-moving type, self-cleaning function is better, not oxidizable, contacts more excellent; Distance between fixed contact and moving contact is large, adds that the setting of two moving contacts constitutes two isolation fractures, therefore arc extinguishing ability and proof voltage impact capacity all stronger.
Accompanying drawing explanation
Structural representation when Fig. 1 is a kind of novel disconnecting link type twin-power switch gate-dividing state of the utility model;
Structural representation when Fig. 2 is a kind of novel disconnecting link type twin-power switch "on" position of the utility model.
In figure: 1, insulator foot 2, insulation movement arm 3, fixed contact 4, moving contact.
Embodiment
Clearly understanding to have technical characteristic of the present utility model, object and effect, now contrasting accompanying drawing and describing embodiment of the present utility model in detail.
As shown in Figure 1 and Figure 2, a kind of novel disconnecting link type twin-power switch, comprise insulator foot 1, the insulation movement arm 2 that can move in parallel along insulator foot 1, being fixed on the fixed contact 3 on insulator foot 1 and being fixed on can with the moving contact 4 of insulation movement arm 2 translation on insulation movement arm 2, described moving contact 4 is respectively equipped with one in insulation movement arm about 2 both sides, and the fixed contact 3 be fixed on insulator foot 1 is also respectively equipped with one in insulation movement arm about 2 both sides.Fixed contact 3 and moving contact 4 when twin-power switch gate-dividing state at distance 0 ~ 26.3 mm on movement arm 2 translation direction that insulate, because distance is large, the utility model can serve as the double power supply converting switch of isolated form, add the setting of two moving contacts 4, constitute two isolation fractures, compared to the twin-power switch of an isolation fracture, electric arc ability of going out is stronger.The utility model adopts disconnecting link type, not oxidizable, and self-cleaning function is better, and contact is more abundant, failure rate is low.
Above content is in conjunction with concrete optimal technical scheme further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection range of the present utility model.
Claims (2)
1. a novel disconnecting link type twin-power switch, it is characterized in that, comprise insulator foot, the insulation movement arm that can move in parallel along insulator foot, being fixed on the fixed contact on insulator foot and being fixed on can with the moving contact of insulation movement arm translation on insulation movement arm, described moving contact is respectively equipped with one in the insulation upper and lower both sides of movement arm, and the fixed contact be fixed on insulator foot is also respectively equipped with one in the insulation upper and lower both sides of movement arm.
2. novel disconnecting link type twin-power switch according to claim 1, is characterized in that, described fixed contact and moving contact are 0 ~ 26.3 mm when twin-power switch gate-dividing state in the distance on movement arm translation direction that insulate.
