Abstract
The utility model belongs to the technical field of electric energy meters and relates to a relay with current transformer and an electric energy meter. The relay with current transformer and the electric energy meter comprise a relay, conductive plates, a current transformer and the like, and are characterized in that the relay is provided with a sampling wiring port and a conductive wiring port,wherein a first conductive plate is electrically connected on the sampling wiring port, the current transformer is sleeved on the first conductive plate for current sampling, a second conductive plate is electrically connected on the conductive wiring port, and the cross sections of the first and second conductive plates are V-shaped or arc plates. The relay and current transformer of the utilitymodel are made in one piece, the conductive plates can be directly connected with a terminal, the structure is simple, the connected nodes are reduced, and the electric resistance of wiring portionsis decreased to the lowest level, thereby reducing the energy consumption of a resistor, lowering heating and guaranteeing the electric energy meter to be provided with excellent stability and reliability.
Description
Technical field
The utility model belongs to the electric energy meter technical field, refers in particular to a kind of relay that is applied on the prepayment meter.
Background technology
Need use relay at the IC-card prepayment meter, relay need be connected with the terminal seat, relay that current prepayment meter adopted and the method for attachment of terminal seat are as follows: junction block is provided with two phase terminal, two zero line terminals, phase terminal and zero line terminals all are located in the junction block, two phase terminal are by the bolt lug plate, lug plate is connected to lead respectively, one of them lead directly with relay on connection jaws conduct electricity connection mutually, another lead is connected with current transformer, current transformer is connected with relay again, adopt this connected mode need use many leads, and increase connected node, water conservancy diversion resistance between relay and the junction block is increased, wasted the electric energy of loss on the resistance, increase thermal value, reduced the stability and the reliability of electric energy meter, had influence on the life-span of whole electric energy simultaneously again.
The utility model content
It is a kind of through the improved relay that is applied to prepayment meter that the purpose of this utility model is to provide, and it is simple in structure, temperature rise is lower, have stability and reliability preferably.
The purpose of this utility model is achieved in that
A kind of relay of belt current mutual inductor, comprise relay, current-carrying plate, current transformer etc., it is characterized in that: described relay is provided with sampling connection jaws and conductive connection mouth, on the sampling connection jaws, be electrically connected with one first current-carrying plate, be set with current transformer on first current-carrying plate and carry out current sample, be electrically connected with one second current-carrying plate on the conductive connection mouth, the cross sectional shape of described first current-carrying plate and second current-carrying plate is " V " shape or arc.
Above-mentioned sampling connection jaws and conductive connection mouth are in the not ipsilateral of relay.
Above-mentioned sampling connection jaws is below relay, and the conductive connection mouth is in the side of relay.
The first above-mentioned current-carrying plate and the length of second current-carrying plate are enough to reach the bottom of terminal seat.
A kind of prepayment meter has used the relay of above-mentioned belt current mutual inductor.
Compared with prior art, the relay of belt current mutual inductor of the present utility model is made an integral body with relay and current-carrying plate, current transformer, not re-using lead connection or screw connects, reduced connected node, make the resistance of wiring part be reduced to floor level, thereby reduce the resistance energy consumption, reduced thermal value, guarantee that electric energy meter has good stable and reliability.Simultaneously since this relay do as a whole, in the time of can reducing the millwright.
