Abstract
The utility model discloses a temperature-rise on-line monitoring system of a switch cabinet contact terminal, in particular an on-line monitoring system which is used for measuring the temperature rise of the switch cabinet contact terminal in the high-voltage environment in the electric power field. The on-line monitoring system consists of a sensor, a receiver and a host, wherein the sensor is fixed on a contact terminal arm or a bus and used for monitoring the ambient temperature and the contact terminal temperature, the monitored data is transmitted into the receiver through the sensor in a wireless communication way, and the receiver transmits the received data into the host for displaying through a cable; and the host can be independently operated and can also upload data so as to realize the remote control through a RS 485. The utility model has the advantages of simple structure, convenient installation and easy popularization.
Description
Technical field
The utility model belongs to field of electrical equipment, and the monitoring that refers to be used for to strengthen equipment temperature rise 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, and purpose is to provide a kind of convenient installation, measures the temperature rise on-line real time monitoring system on the switchgear contact accurately.
For realizing that the utility model purpose adopts following technical scheme: a kind of temperature rise monitoring system, it comprises sensor, receiver and main frame three parts, wherein:
Adopt the wireless communication transmission data between described sensor and the receiver.
Adopt the cable ways of connecting to carry out data transmission between described receiver and the main frame.
Described sensor adopts powered battery.
As further improvement of the utility model, described main frame can carry out independent operation also can upload data realization Long-distance Control by RS485 by main frame.
Described sensor can be fixed on screw and also can be banded on the busbar on contact arm or the busbar, and sensing element can be embedded in also can be external in the sensor box.
Described receiver is fixed on the cabinet wall with screw.
Described main frame is installed on the 35mm guide rail or with screw and is fixed on the cabinet wall.
The utility model is compared with existing online temperature rise monitoring system, and its advantage is:
1, the installation site of sensor can be selected according to user's needs.
2, the sensor antijamming capability is strong, guarantees the accuracy of monitoring result.
3, main frame need not perforate, is directly installed on guide rail or the cabinet wall, and is very easy to use.
Description of drawings
Fig. 1, Fig. 2, Fig. 3 are the structural representations of the utility model embodiment.
Fig. 4 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.
Fig. 2 has provided receiver of the present utility model, adopts the wireless communication transmission data with sensor.
Fig. 3 has provided main frame of the present utility model, adopts cable transmission data with receiver.
With reference to figure 4, 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 receiver with wireless communication mode, adopt the cable ways of connecting reportedly to be passed to main frame and the temperature rise situation is shown on the screen of main frame in real time between receiver and the main frame with what it received.
