A kind of temperature monitoring system of switch cabinet
Technical field
The utility model belongs to technical field of electric power, relates to a kind of temperature monitoring system of switch cabinet particularly.
Background technology
For electric system, equipment in During Process of Long-term Operation, the bus contact joint in switch cubicle, the positions such as high-voltage cable joint are because of aging or contact resistance is excessive and generate heat, accumulation along with heat makes temperature too high, causes adjacent insulating element performance degradation, even punctures and cause the accident.To the bus contact joint in switch cubicle, the temperature at the positions such as high-voltage cable joint is effectively monitored, and effectively can prevent the generation of this type of accident.But, when electric system is in running status, in order to ensure safety, switch cubicle is in a closed state, various and the bad environments of measured positional structure, patrol officer uninterruptedly can not monitor switch cubicle, just can not Timeliness coverage when abnormal heating appears in electrical equipment, also just can not dispose timely.
Summary of the invention
The utility model object is as solving the problem and provides one can carry out Real-Time Monitoring, and structure is simple, the temperature monitoring system of switch cabinet that safety and reliability is high.
For this reason, the utility model discloses a kind of temperature monitoring system of switch cabinet, comprise temperature-detecting device, control module, radio receiving transmitting module and wireless monitor alarm module, wherein:
Multiple temperature-detecting device, for the temperature of the contact multiple to be measured in respectively detector switch cabinet and cable adapter, and is transferred to control module by the temperature data measured;
A control module, for processing the temperature data received, and is transferred to radio receiving transmitting module by the temperature data after process;
A radio receiving transmitting module, for being resolved by the temperature data received, and is wirelessly sent to monitoring, alarming module;
A wireless monitor alarm module, for the data of this radio receiving transmitting module of wireless receiving, and reports to the police.
Further, described temperature-detecting device is temperature sensor testing circuit.
Further, described control module is single chip machine controlling circuit.
Further, described radio receiving transmitting module comprises wireless router.
Further, described wireless monitor alarm module comprises radio communication circuit, buzzer circuit and indicator light circuit.
Further, described wireless monitor alarm module is also connected with key circuit.
Further, described wireless monitor alarm module is also connected with display circuit.
Advantageous Effects of the present utility model:
The utility model can carry out lasting Real-Time Monitoring to the temperature of the contact to be measured of each in switch cubicle and cable adapter, to solve the problem that patrol officer can not carry out uninterrupted monitoring, and system architecture is simple, and cost is low, practical convenient, safety and reliability is high.

Embodiment
Now with embodiment, the utility model is further illustrated by reference to the accompanying drawings.
As shown in Figure 1, a kind of temperature monitoring system of switch cabinet, comprises temperature-detecting device 100, control module 200, radio receiving transmitting module 300 and wireless monitor alarm module 400.In this specific embodiment, temperature-detecting device 100 is temperature sensor testing circuit, control module 200 is single chip machine controlling circuit, certainly, in other embodiments, also can be PLC control circuit or MCU processor control circuit, radio receiving transmitting module 300 includes wireless router, and wireless monitor alarm module 400 comprises radio communication circuit, buzzer circuit and indicator light circuit.Multiple temperature sensor 100 is arranged on the contact of each needs test and the place of cable adapter in switch cubicle respectively, for the temperature of detection contact and cable adapter, the own independence of each temperature sensor 100 and have unique IP address, the temperature of each contact can accurately be reflected when transmitting and monitor, to ensure the reliability of warning and convenient maintenance.The signal output part of temperature sensor 100 connects the signal input part of single-chip microcomputer 200, and the temperature data measured is transferred to single-chip microcomputer 200.Single-chip microcomputer 200 processes the temperature data received and deposits.Radio receiving transmitting module 300 is arranged in the intermediate course of switch cubicle, and carry out communication with single-chip microcomputer 200 and be connected, to receive the temperature data after single-chip microcomputer 200 process, then the temperature data received is sent to wireless monitor alarm module 400 by wireless router, and through domain name mapping, determine each transmitted contact and the temperature data of cable adapter one by one.Wireless monitor alarm module 400, preset temperature range when each contact and cable adapter normally work, when the temperature data transmitted does not meet this scope, wireless monitor alarm module 400 controls the pilot lamp be arranged on switch cubicle and lights, simultaneously, the control hummer be arranged on switch cubicle sounds and reports to the police, in this switch cubicle of prompting operation maintenance personnel, the temperature of relevant contact or cable adapter has exceeded the preset temperature higher limit preset, this imply that the electrical equipment in this switch cubicle may have occurred fault, operation maintenance personnel can be safeguarded timely this switch cubicle according to this warning message or keep in repair, thus avoid the further deterioration of unfavorable condition.
Further, in this specific embodiment, wireless monitor alarm module 400 is also connected with key circuit 500, and key circuit 500 is keyboard or touch-screen, for carrying out setting and the amendment of normal temperature range to user.
Further, in this specific embodiment, wireless monitor alarm module 400 is also connected with display circuit 600, and display circuit 600 is liquid crystal display or OLED display, for displays temperature setting value and measured value and warning information, is convenient to user and checks.
Although specifically show in conjunction with preferred embodiment and describe the utility model; but those skilled in the art should be understood that; not departing from the spirit and scope of the present utility model that appended claims limits; can make a variety of changes the utility model in the form and details, be protection domain of the present utility model.
