Abstract
The invention discloses a wireless radio frequency temperature measurement system, which comprises a temperature measurement module, a receiving module, a control device and a client, wherein the temperature measurement module is used for measuring the temperature of an object to be measured; the receiving module is used for receiving a signal which is transmitted from the object to be measured; the control device is in coupling connection with the temperature measurement module and the receiving module; and the control device sends a measurement signal to the client through a radio frequency transmitting module. The wireless radio frequency temperature measurement system adopts a mode of wirelessly transmitting a temperature signal, has an excellent insulating function and can isolate high voltage in a switch cabinet, so a wireless temperature measurement module can be directly arranged on a high-voltage contact in the switch cabinet, the operating temperature of the high-voltage contact is accurately measured, and the contact temperature of the operating switch cabinet can be monitored in an on-line mode.
Description
Technical field
The present invention relates to a kind of temp measuring system, particularly a kind of less radio-frequency temp measuring system.
Background technology
In electric system, high-tension electricity device such as closed high-voltage switch gear, high-voltage motor, bus and power equipment exist load current and the positively related rule of temperature: temperature when load current increases, can occur and raise, and the phenomenon that load current can occur lowering the temperature when reducing.The temperature variation of electrical equipment might make relevant superstructure loosening, insulating property deterioration, even punctures.Simultaneously, in equipment long-time running process, positions such as its line contact bus row junction are because of wearing out or contact resistance is excessive generates heat, and the temperature of these heating positions can't be monitored, and finally may cause interruption of service thus.According to statistics, electric system has an accident has considerable part relevant with problems of excessive heat in the reason, and therefore adopt an effective measure monitoring bus and electrical pickoff temperature are the problems that electric system need solve.
Because bus is in noble potential, at present domesticly be specifically designed to high voltage bus and electrically contact instrument that heating measures also seldom, the temperature monitoring main method of equipment in the electric system is taked following several method:
The one, be coated with the luminescent material that one deck varies with temperature color at electrical contact surface, come roughly to determine temperature range by observing its change color, low, the poor reliability of this method accuracy can not be carried out quantitative measurment, and needs manually-operated efficient not high.
Another method is the optical fiber type temp measuring system, can the displays temperature value, but because each point for measuring temperature all needs independently optical fiber and signal converter, and wiring, wiring are complicated, the bending radius of optical fiber can not be less than 20 millimeters, and temperature-sensitive optical fiber is fragile, maintenance is big.Fibre Optical Sensor can not move, and uses extremely inconvenience in drawer-type switch cabinet etc. need often be safeguarded the equipment of verification, therefore seldom adopts.Also have the infrared probe temp measuring system, can on-line monitoring, but because system stability is not high, especially affected by environment serious, report more, also employing seldom.In addition, also have the infrared thermometer of (infrared) hand-held radiation characteristic, accuracy of measurement is higher, but owing to adopted the fixedly optical device of D/S, uses inconvenience in specific occasions such as closed high-tension switch cabinets, can't on-line measurement.
Summary of the invention
The object of the present invention is to provide a kind of wireless temperature measurement that carries out, and can send the less radio-frequency temp measuring system of information to the given client end.
