Abstract
The utility model discloses an intelligent electric leakage controller of single -phase detection and temperature detection function three -section protection has, including singlechip, current transformer, zero sequence mutual -inductor, voltage measurement circuit, temperature sensor, signal acquisition circuit, communication circuit and clock circuit, current transformer, zero sequence mutual -inductor, voltage measurement circuit and temperature sensor pass through signal acquisition circuit and all be connected with the singlechip. The utility model discloses at low -voltage power supply network network deployment in -process, carry out the selectivity to the protective circuit breaker's of the superior and the subordinate in the system long delay with short delay time and adjust, make the superior and the subordinate's circuit breaker protect according to certain logical chronogenesis, break down when the product moves, through single -phase detection function and temperature detection function, can judge failure cause and type rapidly, make the solution rapidly to effectively reduce the area that has a power failure, promote the power consumption reliability, reduce electric wire netting equipment selection cost.
Description
Technical field
The utility model relates to leakaging controller technical field, particularly relates to one and has single-phase detection and the intelligent leakaging controller of temperature detecting function three section protection.
Background technology
The protection of existing intelligent electric leakage controller No-mistake Principle long delay, short circuit short time-delay, single-phase detection and temperature detecting function, short circuit is instantaneous is protected by thermo magnetic trip release.Thermo magnetic trip release comprises heat dropout, electromagnetic trip two functions, and it is by electric current time delay heating distortion promotion dropout transmission mechanism that heat is threaded off; It is driven by the instantaneous promotion armature of the short circuit current of solenoid to thread off that magnetic is threaded off.The short circuit instantaneous protection sensitivity of thermo magnetic trip release is low, not easily adjust; Without single-phase detection and temperature detecting function, when product breaks down, can not judge rapidly immediately.
Utility model content
The utility model object is exactly the defect in order to make up prior art, provides one to have single-phase detection and the intelligent leakaging controller of temperature detecting function three section protection.
The utility model is achieved through the following technical solutions:
One has single-phase detection and the intelligent leakaging controller of temperature detecting function three section protection; include single-chip microcomputer, current transformer, zero-sequence transformer, tension measuring circuit, temperature sensor, signal acquisition circuit, communicating circuit and clock circuit; described current transformer, zero-sequence transformer, tension measuring circuit are all connected with single-chip microcomputer by signal acquisition circuit with temperature sensor; described single-chip microcomputer is also connected with described communicating circuit and clock circuit respectively, and the control signal output interface of single-chip microcomputer is connected with magnetic flow convertor by drive circuit.
Intelligent controller with three-stage protection function adopts single-chip microcomputer to be main control unit, converts the voltage of major loop, electric current, electric leakage signal, Switch main body temperature signal to digital signal by current transformer, zero-sequence transformer, voltage measurement circuit, temperature sensor through signal sample circuit.Single-chip microcomputer carries out calculation process to these signals and compares with internal protection setting value, exports corresponding control signal, and control signal drives magnetic flow convertor to thread off through dropout driver circuit.Outer clock circuit provides the real-time time of accurate stable for system, so that plant maintenance personnel can inquire about detailed history numeration certificate.Temperature sensor provides the temperature data of current operating environment for system, when time too high or too low for temperature, send system alarm.
The utility model has the advantages that: the utility model, in low voltage electric network networking process, carries out selectivity to the long delay of the superior and the subordinate's protective circuit breaker in system and short time delay time and adjusts, the superior and the subordinate's circuit breaker is protected by certain logical sequence; Break down when product runs, by single-phase measuring ability and temperature detecting function, failure cause and type can be judged rapidly, make solution rapidly, thus effectively reduce power failure area, promote electricity consumption reliability, reduce grid equipment type selecting cost.
