It is preferred that, the detection module includes voltage sensor, hygrosensor and data converter, the temperature sensing Device, voltage sensor are connected through data converter with controller;The voltage sensor, hygrosensor are described to be multiple Voltage sensor, hygrosensor are waken up once every preset time t, and packet is sent to the controller;The packet Including temperature signal and battery voltage signal.
It is preferred that, the controller wakes up once every preset time t, detects network connection state after wake-up first, if Network connection is normal, then detects whether receive temperature signal in preset time t, if continuous three times do not receive, alarmed, If receiving temperature signal, whether detection temperature signal exceedes the upper limit, if more than the upper limit, being alarmed;Detect cell voltage Whether signal exceedes the upper limit, if more than the upper limit, being alarmed.
It is preferred that, the hygrosensor does not receive the feedback signal of controller transmission in preset time t, then sends out again Send packet.
It is preferred that, the preset time t is 3-5min.
Beneficial effects of the present invention are as follows:
The present invention sets the temperature data in temperature detecting module, collection cabinet in the cabinet of high voltage power distributing cabinet, passes through With the comparison of temperature data under normal circumstances, the operating environment condition of power distribution cabinet inner high voltage equipment is obtained, is realized to high voltage power distribution The monitoring of cabinet in-cabinet temperature, and find in-cabinet temperature abnormal conditions, so as to and alarm, it is to avoid the generation of accident.
The present invention can detect busbar for power distribution cabinet temperature, and the temperature change of busbar represents busbar contacts status, if temperature is super Upper limit threshold is crossed, then illustrates contact fault, controller alarm.The hygrosensor of the present invention is sent once every preset time t Packet, controller wakes up once every preset time t, for receiving and treatment temperature and battery voltage signal, it is to avoid frequency Numerous refresh data causes hardware damage, and reduces power consumption.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing There is the accompanying drawing used required in technology description to be briefly described, it should be apparent that, drawings in the following description are only this Some embodiments of invention, for those of ordinary skill in the art, without having to pay creative labor, may be used also To obtain other accompanying drawings according to these accompanying drawings.
Fig. 1 is a kind of structured flowchart of high voltage power distributing cabinet of the invention.
Embodiment
Embodiment 1:
The present invention provides in a kind of high voltage power distributing cabinet, including cabinet, cabinet and sets voltage transformer, current transformer, leakage Electrical protective device, circuit breaker operation mechanism, vacuum circuit breaker, alarm module, detection module and controller, voltage transformer, electricity Current transformer, earth leakage protective device, circuit breaker operation mechanism, alarm module, detection module are connected with controller, vacuum circuit breaker Device is connected with circuit breaker operation mechanism.
By setting the temperature data in detection module, collection cabinet in the cabinet of high voltage power distributing cabinet, by what is collected The comparison of temperature data and temperature data under normal circumstances, obtains the operating environment condition of power distribution cabinet inner high voltage equipment, realization pair The monitoring of high voltage power distributing cabinet in-cabinet temperature, and find in-cabinet temperature abnormal conditions, so as to and alarm, it is to avoid the hair of accident It is raw.Alarm module uses audible-visual annunciator, for unusual condition alarm, when temperature anomaly or electric voltage exception, controller alarm Alarm module is locally being alarmed.
The present invention can detect busbar for power distribution cabinet temperature, and the temperature change of busbar represents busbar contacts status, if temperature is super Upper limit threshold is crossed, then illustrates contact fault, controller alarm.The hygrosensor of the present invention is sent once every preset time t Packet, controller wakes up once every preset time t, for receiving and treatment temperature and battery voltage signal, it is to avoid frequency Numerous refresh data causes hardware damage, and reduces power consumption.
Embodiment 2:
As shown in figure 1, the present invention, which is provided in a kind of high voltage power distributing cabinet, including cabinet, including cabinet, the cabinet, sets electricity Press transformer, current transformer, earth leakage protective device, circuit breaker operation mechanism, vacuum circuit breaker, alarm module, memory module, Communication module, detection module and controller, institute's voltage transformer, current transformer, earth leakage protective device, breaker operator machine Structure, alarm module, memory module, communication module, detection module are connected with the controller, the vacuum circuit breaker and open circuit Device operating mechanism is connected.Alarm module is alarmed for unusual condition, when temperature anomaly or electric voltage exception, controller alarm alarm Module is locally being alarmed, and by alert event storage in a storage module, convenient inquiry.Communication module be used for controller with it is upper Communication between machine, controller can be uploaded to warning message in host computer by communication module.
Detection module includes voltage sensor, hygrosensor and data converter, and hygrosensor is supplied by high-energy battery Electricity.Hygrosensor is arranged on the heat generating spot in cabinet, and the heat generating spot is included on high voltage bus and high-voltage switch gear.Set in cabinet Multiple hygrosensors and voltage sensor are put, voltage sensor is used for the voltage signal for gathering high-energy battery.Battery electric quantity with Time passage is gradually reduced, and cell voltage is gradually reduced, and when brownout, hygrosensor can not then work, therefore by electricity Pressure sensor collects cell voltage, sends voltage signal to controller, is compared in controller, if the electricity detected When pressure value is less than threshold value, alarm module alarm reminds attendant to change battery in time.
Hygrosensor is waken up once every preset time t, and packet is sent to controller;Packet includes temperature signal And battery voltage signal.Such as preset time t is 3-5min, and packet is sent to controller every 3-5min hygrosensors, Detected after transmission whether received within the period controller transmission receive the feedback signal of data, if not receiving feedback letter Number, then hygrosensor resends packet.
Controller can receive the signal of multiple hygrosensors and voltage sensor, hygrosensor and voltage sensor away from From controller farther out, relaying can be increased.Controller wakes up once every preset time t, and preset time t is 3-5min, after wake-up Network connection state is detected first, if network connection is normal, detects whether receive temperature signal in preset time t, if even Continue three times and do not receive, then alarmed, if receiving temperature signal, whether detection temperature signal exceedes the upper limit, if more than the upper limit, Then alarmed;Detect whether battery voltage signal exceedes the upper limit, if more than the upper limit, being alarmed.
In the embodiment, to reduce wrong report, only when all can not receive temperature signal continuous three times, controller control alarm mould Block is alarmed, and alarm module can use audible-visual annunciator, while by communication module, warning message is uploaded into host computer, in time Repaired by attendant.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and Within principle, any modification, equivalent substitution and improvements made etc. should be included in the scope of the protection.
