Abstract
The utility model discloses a monitoring device, in particular an on-line monitoring system which is used for measuring the temperature rise of a switch cabinet contact terminal in the high-voltage environment in the electric power field. The on-line monitoring system is mainly used for monitoring the on-line temperature rise of a joint part and a contact terminal of an indoor high-voltage switch device with 2kV-35kV/50Hz. A sensor which supplies power through adopting batteries is arranged according to a measuring position, and the sensor can monitor the temperature at six positions on line and obtain the temperature rise situation through comparing the monitoring point temperature with the external temperature; and when the temperature rises to a setting value, an alarming prompt is provided and is output to display through a monitor. The on-line monitoring system adopts a pattern design, which is simple, intuitive and convenient for operating.
Description
Technical field
The utility model belongs to field of electrical equipment, and the monitoring that refers to be used for to strengthen the temperature rise of equipment that hyperbaric environment is moved especially requires and the temperature rise on-line monitoring system that designs.
Background technology
Contact in the switch cubicle is one of critical component of the normal operation of switch cubicle, if but contact exceeds rational temperature rise long-time running will cause insulator damage and cause major accident.
The 11.7.2 regulation will be strengthened the supervision to the operational outfit temperature rise in State Grid's grid company " 18 great anti-accident measures of electrical network ", can be used on the market at present realize that the product of above-mentioned functions also has a lot of shortcomings when realizing monitoring function, in high-risk occasions such as high voltage highfields, there are potential safety hazards such as electric leakage in the power supply mode of the direct power taking of high voltage bus, traditional monitoring technology can not directly be touched switch contact, be difficult in and carry out thermometric near direct contact contact or the contact and cause the result who measures not accurate enough, if and adopt mode such as infrared to monitor, to the very high installation inconvenience that causes equipment of requirement of installing, adopt communication products such as optical fiber, when many cabinets link, can produce the phase mutual interference, also can cause measuring inaccurate.
The utility model content
The utility model is at the shortcoming of prior art, purpose be to provide a kind of convenient installation, measure the temperature rise on-line real time monitoring system on the switchgear contact accurately, mainly be applicable to the joint area of 2KV-35KV/50HZ indoor high voltage switchgear or the online intensification monitoring at contact position.
For realizing that the utility model purpose adopts following technical scheme: a kind of temperature rise monitoring system, it comprises sensor and display, wherein display has the function that receives data concurrently.
Described display can receiving sensor the data of transmission.
Adopt wireless communication mode transmission data between described sensor and display.
Described sensor adopts powered battery, and wherein the electric weight of battery can be kept 3 to 6 years.
As further improvement of the utility model, described sensor can on-line monitoring 6 place's temperature.
Described sensor shows monitoring result with the temperature rise situation that monitors by display.
Described display adopts the figure setting, and simple, intuitive also has the alarm history look facility.
As further improvement of the utility model, described monitoring system is carried out intelligent decision and is exported by three groups of passive relays after any one tunnel temperature rise reaches setting value.
The utility model is compared with existing online temperature rise monitoring system, and its advantage is: sensor adopts powered battery and can monitor 6 place's temperature simultaneously, and sensor is installed and is directly installed near the position monitoring point, has guaranteed the accuracy of measuring to a certain extent; Adopt the figure setting with the matching used display of sensor, simple, intuitive has the alarm history look facility simultaneously.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the user mode synoptic diagram of utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
Fig. 1 has provided sensor of the present utility model, can be directly be installed near contact or the joint appropriate location according to client's concrete needs.
With reference to figure 2, during use, sensor is compared the temperature that monitors with environment temperature, draw the temperature rise situation of monitoring point, and comparative result is transferred to display with wireless communication mode, the display that receives data shows the temperature rise situation on display screen in real time, and reaches in any one tunnel temperature rise and to provide the Three Estate alarm after setting numerical value: early warning, report to the police, transfinite and with pilot lamp, liquid crystal instead show, audible alarm, intelligent decision and three groups of passive relays outputs.
