Abstract
The utility model discloses a relay used on an electric meter, especially a relay with a current divider, as an element device for measuring the current and the cut-off load. The relay with the current divider is capable of reducing the volume of the electric meter by about 30% and has features of small resistance of the circuit loop, low heating amount, convenient installation and low cost. The relay comprises a current divider and a relay, wherein the current divider is fixed in the shell of the relay and a composite contact is fixed on the current divider; when the relay is closed, a movable contact slice of the relay contacts with the composite contact on the current divider; when the relay is open, the composite contact of the current divider does not contact with the movable contact slice of the relay. The relay has features of reduced volume, simple structure, small resistance of the circuit loop, convenient installation and low cost.
Description
Technical field
The utility model relates to the relay that uses on a kind of electric energy meter, and especially with the relay of shunt, it is a kind of components and parts of measuring electric current and cutting off load.
Background technology
In the design of electric energy meter circuit, shunt and relay are the devices that separately assembles all the time, and shunt is fixed on the terminal box binding post of meter case, and is connected with lead with wiring board; Relay is installed on the wiring board of electric energy meter and is fixed on the terminal box on the electric energy meter shell by the electric current line, and shared electric energy meter volume inside is big.In the circuit design of electric energy meter, shunt mainly be in circuit design, to use as sample resistance; Relay mainly is to load in the circuit design and use as cutting the relay road.Their separately assembling, cause the enclosure volume of ammeter big, and existing designing technique, can make the whole loop resistance of electric energy meter circuit big, complex structure, interface unit is too much, the whole caloric value of electric energy meter is big, and that interface unit is copper product is made, and copper product cost height can cause the cost height of electric energy meter; The volume of electric energy meter is big, the cost of electric energy meter also thereupon in all its bearings, the most tangible is exactly that the electric energy meter shell is big, cost height, and to installing in the limited place of electric energy meter installing space, can bring series installation inconvenience.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and can make electric energy meter volume-diminished about 30%, circuit loop resistance is little, caloric value is low, the relay of easy for installation, band shunt that cost is low.
The relay of the utility model band shunt comprises shunt and relay; Described shunt is fixed in the housing of relay, be fixed with composite contact on the described shunt, relay is when closure, and the movable contact spring of relay contacts with composite contact on the shunt, relay is when opening, and the composite contact of shunt does not contact with the movable contact spring of relay.
Described shunt is fixed on interior fixing can being meant by screw of housing of relay, also can be that a groove is arranged in relay, and shunt inserts in this groove, thereby plays fixing.
The fixing of described composite contact and shunt can be porose on shunt, and composite contact is similar to the riveting of rivet sample on this hole, thereby forms fixing; Also can screw or pin be fixed on the shunt.
The material of described composite contact can be that silver or silver alloy and red copper are composited.
The relay of this band shunt is when work, and relay is in opening, and the composite contact on the shunt does not contact with the movable contact spring of relay, when relay closes, the movable contact spring of relay contacts with the composite contact of shunt, and electric current is by shunt, shunt work.
Relay according to above-described band shunt, the volume-diminished that on electric energy meter, accounts for thereby the volume of electric energy meter can dwindle, the minimizing of connecting line, make the cost of electric energy meter further reduce, owing to reduced a large amount of jockeys, jockey is few, and the caloric value of circuit loop is little, so greatly reduce the whole caloric value of electric energy meter.Described easy for installation, adopt electric energy meter of the present utility model, after the whole ammeter volume-diminished 30%, also can decrease the requirement of installing space size.
Have the volume-diminished that makes electric energy meter, simple in structure, characteristics such as whole electric energy circuit loop resistance is little, easy for installation, cost is low according to the relay of above-described band shunt.
