Abstract

Provided is a triphase electric power open-phase protector, relating to the open-phase protector technology field. The triphase electric power open-phase protector comprises a plurality of power-off clutches (F) connected with an emergency breaker (E) via a push rod (B), wherein each power-off clutch (F) is connected with the wire inlet end of the triphase electric power respectively; both the wire inlet end and the cathode end of the triphase electric power are connected with one end of the emergency breaker (E); the exterior of the emergency breaker (E) is provided with an emergency breaker external handle (D); the interior of the emergency breaker (E) is provided with a power supply entry point (A) and a power supply outlet point (C) which are mutually connected; and the power supply outlet point (C) is connected with the triphase electric power outlet end. The triphase electric power open-phase protector solves the problem that the triphase electric power open-phase can not automatically power off, thereby fundamentally eliminating the damage upon the electric resulting from open-phase, cutting the cost of the electric appliances produced in enterprises, substantially saving production time, and having bright market prospects.

Description

The three-phase electricity open phase protector
Technical field:
The utility model relates to the open phase protector technical field, is specifically related to a kind of novel three-phase electricity open phase protector.
Background technology:
Along with the more factory and enterprise of the development of modern industrialization has been realized electrified, automation, but in the production process of reality, fail to solve three-phase power always; Unexpected phase shortage is to the damage problem of electrical equipment in the production process; Though on the market many Protector for electric appliance are arranged now, all be ground connection, earth leakage protective, be a blank to phase shortage tripping operation outage always; Normal operation generation to a lot of factories of enterprise brings very big influence, brings many economic losses to enterprise simultaneously.
The utility model content:
The purpose of the utility model provides a kind of three-phase electricity open phase protector; It has solved the problem that the three-phase electricity phase shortage can not be cut off the power supply automatically; Thereby from fundamentally having solved phase shortage to electric infringement; Make the electrical equipment in the enterprise production can reduce cost, practiced thrift the very big production time, very big market prospects are arranged.
In order to solve the existing problem of background technology; The utility model is to adopt following technical scheme: it comprises push rod B, the emergent external handle D of decoupler, emergent decoupler E and outage clutch F; Several outage clutches F is connected with emergent decoupler E through push rod B; Each clutch F that cuts off the power supply is connected with the end of incoming cables of three-phase electricity respectively, and the end of incoming cables of three-phase electricity all is connected with emergent decoupler E one end with negative pole end, and emergent decoupler E outer setting has the external handle D of emergent decoupler; Emergent decoupler E set inside has interconnective power supply inlet point A and power outlet point C, and power outlet point C is connected with the three-phase electricity leading-out terminal.
Described power supply inlet point A breaks off and closing contact (slidingtype contact) for emergent; Power outlet point C is the output contact (sliding contact) of emergent decoupler.
The principle of the utility model is: after the outage clutch, will meet an urgent need simultaneously decoupler E and source inlet point A of push rod B return breaks off integral body and cuts off the electricity supply, and after the power supply automatic disconnection, needs the external handle D of the decoupler energized once more of meeting an urgent need of operation manually.Under the effect of outage clutch F, the inner power supply inlet point A of emergent decoupler E is broken off with power outlet point C, reach the cut-out general supply purpose, thereby protect electrical equipment to avoid damaging because of phase shortage.
The utility model has solved the problem that the three-phase electricity phase shortage can not be cut off the power supply automatically, thereby from fundamentally having solved phase shortage to electric infringement, makes the electrical equipment in the enterprise production can reduce cost, has practiced thrift the very big production time, and very big market prospects are arranged.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
With reference to Fig. 1; This embodiment adopts following technical scheme: it comprises push rod B, the emergent external handle D of decoupler, emergent decoupler E and outage clutch F; Several outage clutches F is connected with emergent decoupler E through push rod B; Each clutch F that cuts off the power supply is connected with the end of incoming cables of three-phase electricity respectively, and the end of incoming cables of three-phase electricity all is connected with emergent decoupler E one end with negative pole end, and emergent decoupler E outer setting has the external handle D of emergent decoupler; Emergent decoupler E set inside has interconnective power supply inlet point A and power outlet point C, and power outlet point C is connected with the three-phase electricity leading-out terminal.
Described power supply inlet point A breaks off and closing contact (slidingtype contact) for emergent; Power outlet point C is the output contact (sliding contact) of emergent decoupler.
The principle of this embodiment is: after the outage clutch, will meet an urgent need simultaneously decoupler E and source inlet point A of push rod B return breaks off integral body and cuts off the electricity supply, and after the power supply automatic disconnection, needs the external handle D of the decoupler energized once more of meeting an urgent need of operation manually.Under the effect of outage clutch F, the inner power supply inlet point A of emergent decoupler E is broken off with power outlet point C, reach the cut-out general supply purpose, thereby protect electrical equipment to avoid damaging because of phase shortage.
This embodiment has solved the problem that the three-phase electricity phase shortage can not be cut off the power supply automatically, thereby from fundamentally having solved phase shortage to electric infringement, makes the electrical equipment in the enterprise production can reduce cost, has practiced thrift the very big production time, and very big market prospects are arranged.
