Description
Technical field
It the utility model is related to protection device for circuit breaker.
Background technology
Breaker is a kind of electric current that can either be closed, carry and cut-off under normal loop condition, and can close, advise
The switching device of the electric current under abnormal loop condition (including short circuit condition) is carried and cut-off in the fixed time.And usually,
It is divided into two kinds of high pressure and low pressure, high-voltage circuitbreaker is generally used for the places such as factory, power plant, and substation, with our ordinary peoples
Relatively be then low-voltage circuit breaker.
With the continuous development of national economy, the application of low-voltage circuit breaker is more and more extensive, and low-voltage circuit breaker is had by purposes
Protect motor, protection transformer, protection electric distribution line, protection illuminating line and electrical shock protection etc..Transported for a long time in breaker
In capable process, as on-off times increase, and the operation that is powered for a long time, there is certain shadow to breaker service life
Ring, the service life of general low-voltage circuit breaker switch, also there was certain limitation in its conduction time, if low pressure is breaking at 6000 times or so
Device exceeds service life, does not replace in time, it will causes serious security risk.
At present, the low-voltage circuit breaker used is divided into two major class of omnipotent breaker and moulded case circuit breaker.This two class
Breaker does not have service life detection, simply judges by field maintenance person surface, therefore the normal operation of production can be given to bring
Very big puzzlement, there are security risk.
Utility model content
Technical problem to be solved in the utility model is to realize that one kind can monitor breaker service life, ensures electricity consumption
The device of safety.
To achieve these goals, the technical solution adopted in the utility model is：Breaker service life precaution device, early warning
Device is equipped with microprocessor, and the signal input part of the microprocessor connects breaker body by auxiliary contact switch detection circuit
Auxiliary contact switch, the alarm signal output ends of the microprocessor export alarm indication signal to alarm lamp unit.
The microprocessor conveys breaker working condition signal by communicating circuit to host computer or storage unit.
The microprocessor conveys breaker working condition signal by communicating circuit to wireless communication unit, the channel radio
Breaker working condition signal is delivered to far-end server or user terminal (such as mobile phone) by letter unit by wireless transmission method.
The breaker drive signal of the microprocessor exports break signal to the divide-shut brake drive circuit of breaker body.
The alarm lamp unit includes being used to indicate the closure indicator light of circuit breaker closing conjunction state, for indicating that breaker breaks
The disconnection indicator light of open state, for indicating that breaker open and close times exceed the first early warning indicator light of threshold value, and for referring to
Show that the breaker electrifying cumulative time exceedes the second early warning indicator light of threshold value.
The precaution device body is a housing, auxiliary contact switch detection circuit, microprocessor and the communicating circuit
It is fixed in housing, the alarm lamp unit is fixed on surface of shell.
The utility model breaker service life precaution device, using simple, practical, directly perceived, economic design method, low
Device precaution device on short-circuiting device is pressed, in addition to it can detect the state that breaker is opened or disconnected in real time, can more importantly be examined
Access times and the conduction time of breaker are surveyed, when low-voltage circuit breaker access times and conduction time exceed certain value, precaution device
Police instruction prompting field personnel will be sent and replace breaker in time, break down to avoid breaker and cause the damage of bigger
Lose, ensure Electrical Safety.

Embodiment
As shown in Figure 1, precaution device is equipped with auxiliary contact switch detection circuit 3, microprocessor 4, communicating circuit 5 and alarm
Lamp unit, breaker service life precaution device device is in breaker (such as low-voltage circuit breaker), the inspection of precaution device upper switch detection circuit
The break-make situation of low-voltage circuit breaker auxiliary contact is surveyed, so as to detect the on-off times of breaker and conduction time and be transmitted to micro-
Processor 4STC15F101 chips.
Microprocessor 4 to transmitting the on off state come count the EEPROM of cumulative deposit microprocessor 4, if breaking
Device is in closure state and then carries out timing and add up to be included in EEPROM, and microprocessor 4 judges if on-off times exceed early warning value, point
Bright first early warning indicator light 8, if the breaker electrifying time exceedes time early warning value, lights the second early warning indicator light 9.
While breaker access times and conduction time is monitored, microprocessor 4 monitors breaker in real time and cut-offs state,
Breaker closing indicator light 6 is lighted when breaker is in closure state, breaker, which is off lighting, disconnects indicator light 7,
So as to the electriferous state of more intuitively instruction electrical circuit.
Precaution device also has communication function, can lead on off operating mode and break-make cumulative number that breaker is currently in
Sent in the information such as electric cumulative time to upper electromechanical road.
As shown in Fig. 2, auxiliary contact switch detection circuit 3 detect breaker open off state after, pass through photoelectricity
The switching signal that isolator (optocoupler) produces displacement in its output terminal DIO sends microprocessor 4 to, if microprocessor 4 judges
It is to be in closure state to low-voltage circuit breaker, then adds up open and close times, and accumulative breaker electrifying time, if cumulative number is big
In early warning value, the first early warning indicator light 8 is lighted, if the cumulative time that is powered is more than early warning value, lights the second early warning indicator light 9,
If above-mentioned two numerical value is far more than early warning value, control circuit-breaker switching on-off drive circuit 10, cut-off breaker, prevents accident
Occur.
This precaution device can monitor breaker in real time and open shut-off situation at the same time, if auxiliary contact switch detection circuit 3
Detect that breaker is in opening state, then light closure indicator light 6, if being off state, light disconnection indicator light
7, so that the Electrical Safety of the intuitively powered situation of show circuit, very well prompting staff.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the utility model implements and from above-mentioned
The limitation of mode, if the improvement of the various unsubstantialities of inventive concept and technical scheme of the present invention progress is employed, or not
It is improved by the present invention design and technical solution directly apply to other occasions, the scope of protection of the utility model it
It is interior.
