The intelligent controller has the advantages that the temperature of the contact of the circuit breaker can be monitored in real-time, and a liquid crystal display module is adopted so as to conveniently check various parameters of the operation of the circuit breaker; the controller has beautiful interface and convenient operation; the application of the device can reduce the damage of the contact of the circuit breaker caused by overheat, can prolong the service life of the circuit breaker, and therefore the controller can be directly arranged on a high voltage circuit breaker, thus reducing the overlapping investments of users and faults and hidden dangers caused by secondary construction.
Description
[technical field]
The utility model is about the circuit breaker in the electric switch, is meant a kind of middle vacuum circuit-breaker intelligent controller of pressing especially.
[background technology]
Middle operating state of pressing vacuum circuit-breaker (handcart-type) only can show a deciliter state indication, close branch number of times etc. by mechanical type on the panel of circuit breaker itself; If will realize protection, outside demonstration, control and communication function, join group switch state indicator outside need be on circuit breaker and could realize.The major function of this on off state indicator is by functions such as the operating state of light-emitting diode simulation demonstration circuit breaker (wheeler's formula), deciliter position, ground connection cutter position, energy storage states.
The shortcoming of existing on off state indicator: overall volume is bigger, can't install on the breaker cabinet of small intelligent, and need carry out secondary construction and overlapping investment to breaker cabinet, waste of material so not only, the potential safety hazard of also might work progress bringing.In addition, handcart type breaker is in operation, its dynamic and static contact contact position can be than being easier to heating during by big electric current, and this position is to be operated in the place of band high-tension electricity of sealing, the external world can't carry out real time temperature and detect, cause heating excessively easily, cause too high fault and the accident of causing of temperature.
[summary of the invention]
Technical problem to be solved in the utility model is to provide a kind of miniaturization, safety and middle pressure vacuum circuit-breaker intelligent controller easy for installation.
The utility model solves the problems of the technologies described above by the following technical programs: press the vacuum circuit-breaker intelligent controller in a kind of, comprise digital processing unit, signal contact input unit, infrared remote receiver, LCD, infrared transmitter, transformation coil, and temperature inductor, described signal contact input unit, infrared remote receiver, LCD all are connected to digital processing unit, described transformation coil, and temperature inductor all is connected to infrared transmitter, the mutual communication of described infrared remote receiver and infrared transmitter.
Be connected with main power source and stand-by power supply on the described digital processing unit simultaneously.
Press the advantage of vacuum circuit-breaker intelligent controller to be in the utility model: with the miniaturization of original on off state indicator module, the light-emitting diode that replaces former switch indicator with LCDs, make beautiful interface, and show dynamically that circuit breaker position, spring energy-storage state, switch close the branch state and write down circuit breaker and close/separating brake number of times and nearest 10 times accumulated running time; Adopt infrared sensor to send, receive temperature, realize wireless transmission, the energy real-time online detects the temperature of six contacts, realize that the wireless transmission temperature surpasses set point and can provide functions such as alarm switch error protection operate time, fault alarm, so that stop to take place because of the contact head excessive heating fault that causes and accident; And the design communication interface is arranged, can carry out exchanges data with host computer, to satisfy distribution network automation requirement; Adopt the duplicate supply working method, during the main power source power down, stand-by power supply work is write down time, running status when cutting off the power supply in order to avoid cause nothing to show that controller still can be indicated current state during outage when working power disappears; The intelligent controller of this miniaturization can directly be contained on the primary cut-out, forms the high-voltage intelligent vacuum circuit-breaker, can reduce the secondary construction, makes things convenient for the client.
[description of drawings]
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the circuit block diagram of pressing the vacuum circuit-breaker intelligent controller in the utility model.
[embodiment]
See also Fig. 1, press the vacuum circuit-breaker intelligent controller to comprise digital processing unit 1, signal contact input unit 2, infrared remote receiver 3, LCD 4, infrared transmitter 5, transformation coil 6 in the utility model, and temperature inductor 7.
Above-mentioned signal contact input unit 2, infrared remote receiver 3, LCD 4 all are connected to digital processing unit 1, also are connected with main power source 12 and stand-by power supply 14 on this digital processing unit 1.This main power source 12 can be common civil power, and stand-by power supply 14 can be a reserve battery.Adopt the duplicate supply working method in this circuit, during main power source 12 power down, stand-by power supply 14 startup work show in order to avoid cause not have when working power disappears, intelligent controller still can be indicated the circuit breaker current state during main power source 12 outages, time, running status during the record outage.
Should in press the vacuum circuit-breaker intelligent controller to realize showing that by LCD 4 circuit breaker positions, spring energy-storage state, switch close the branch state and write down circuit breaker and close/separating brake number of times and nearest 10 times accumulated running time etc., press the operation principle of vacuum circuit-breaker intelligent controller as described below in this:
At first signal contact input unit 2 converts the no source contact of circuit breaker to the signal of telecommunication through digital processing unit 1 processing, shows required state or numeral on LCD 4; Infrared transmitter 5, transformation coil 6, and temperature inductor 7 is to be contained in circuit breaker to want on the device of detected temperatures point, this transformation coil 6 is on this device, temperature inductor 7 is installed on this temperature spot that will detect, the working power of this infrared transmitter 5 is to produce through 6 conversion of transformation coil, function course such as boost by the electric current by this temperature spot, so that low pressure position and high pressure position are effectively isolated; Then through the detected temperature signals input of temperature sensor 7 infrared transmitters 5, and convert infrared signal to and launch; The infrared remote receiver 3 that is contained in no charging zone is transferred to digital processing unit 1 through optical cable with signal after receiving the signal of infrared transmitter 5 emissions, exports to LCD 4 again and carries out temperature and show.Simultaneously the also exportable after treatment required signal of communication of contact, temperature infrared signal on digital processing unit 1, outside fail active or do not have source contact; Also can compare, judge, output alarm demonstration or external control signal etc. according to the set point that is input in advance in the digital processing unit 1.
