Description
Technical field
The utility model relates to breaker technical field, more particularly, relates to a kind of novel prepayment ammeter breaker circuit.
Background technology
Along with deepening constantly of national grid transformation, the use of this electric power meter of pre-paying kilowatt-hour meter definite purpose circuit breaker is more and more universal, and the electricity consumption idea of people also changes thereupon simultaneously, and after first power purchase, the consumption pattern of electricity consumption has started the life entering people.But current pre-paying kilowatt-hour meter special miniature breaker is due to the restriction in space, and to place the space of wiring board very little, effective protection circuit cannot be adopted, cause the performance of product anti-lightning surge generally lower than 2.5kV, there is 2.5kV false tripping in portioned product, there is the phenomenon that Partial key components and parts burst in 4kV, greatly affects the reliability of client to product and the primary demand of security.
Therefore, prior art urgently has greatly improved.
Summary of the invention
Be by the novel technical matters that will solve of this reality, for the above-mentioned defect of prior art, a kind of novel prepayment ammeter breaker circuit is provided, comprise: power supply inputs, also comprise: the power circuit be connected in series, delayed releasing circuit and ammeter signal deteching circuit, described power circuit comprises voltage dependent resistor (VDR) RV1, commutation diode D3, current-limiting resistance R5, electrical apparatus release L and voltage stabilizing diode D4; Described delayed releasing circuit comprises resistance R3, R4, electric capacity C2, C3, controllable silicon Q1; Described ammeter signal deteching circuit comprises voltage dependent resistor (VDR) RV2, resistance R1, diode D1, electric capacity C1 and transistor Q2.
Implement novel prepayment ammeter breaker circuit of the present utility model, there is following beneficial effect: before power circuit adopts electrical apparatus release L to be placed on voltage dependent resistor (VDR) RV1, and ammeter signal deteching circuit adopts Surge suppression process, effectively can solve the performance of current prepaid ammeter special miniature breaker anti-lightning surge generally lower than 2.5kV, portioned product occurs that the problem that Partial key components and parts burst appears in 2.5kV false tripping and 4kV, greatly improves reliability and the security of product; Delayed releasing circuit improves delay precision and reliability greatly, meets the functional requirement of pre-paying kilowatt-hour meter special miniature breaker completely; Whole circuit design is simple, and anti-electromagnetic compatibility characteristic is strong, more meets the actual demand of user.
