Many buses and switch are in noble potential, at present domesticly are specifically designed to high voltage bus, high-voltage switch gear and electrically contact instrument that heating measures also seldom.The method of temperature monitoring, a kind of is to be coated with the temperature variant luminescent material of one deck color at the high-tension electricity surface in contact, comes 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; Another method is to utilize the thermal infrared imager of radiation characteristic, and accuracy is higher, but owing to need optical device, it is not too convenient to use in specific occasions such as high-tension switch cabinets, and price is higher, has applied certain difficulty.The more important thing is that above dual mode all needs manually to patrol, can not obtain temperature data in real time, resulting data lag behind forever, do not have temperature Realtime Alerts function.And the electronic instrument of wire communication mode does not meet power high voltage environment measurement instrument standard.
The utility model content:
We have solved the problems referred to above of present existence at " the power high voltage environment wireless temperature measurement terminal " of research and development, can under hyperbaric environment, accurately measure temperature, can meet the requirement of hyperbaric environment instrument fully, can be under hyperbaric environment accurately and timely deal with data, transmission data, for the power industry safety in production provides more effective surveillance and control measure.
The wireless temperature measurement terminal is powered by high-energy battery, reduce the electrical link between the high-low pressure, adopt digital mode to work, temperature sensor is attached to (high voltage bus or high-voltage switch gear) on the heat generating spot, and be connected with the wireless data transducer (temperature sensor and data converter are called the wireless temperature measurement terminal together) by the one piece of data line, this terminal attached on high voltage bus or the high-voltage switch gear and long-term work in hyperbaric environment.The wireless temperature measurement terminal directly or through radio repeater station sends temperature signal to wireless convergence terminal by wireless mode,
Technical characteristic:
1, exempts from demand frequency 433MHz
2, real-time: real time on-line monitoring
3, upload in real time: can upwards transmit data by setting-up time
4, low-power consumption: the low-power consumption high sensitivity adopts high-energy battery, with 60 minutes be the transmission cycle of data, sustainable 3-5, but also self-powered
5, accuracy: measuring accuracy can reach ± and 0.5 ℃
6, high reliability; High-insulativity and anti-electromagnetic field interference
7, dirigibility: the user can be provided with parameter flexibly, easily according to the demand of oneself, is convenient to installation and maintenance
8, confidentiality: but transparent transmission, also can data encryption
The utility model purpose is to realize like this, a kind of power high voltage environment wireless temperature measurement terminal, it is characterized in that this power high voltage environment wireless temperature measurement terminal becomes shell by the strong plastics die mould of weather resisteant, embedded digital formula temperature sensor, temperature sensor is connected on the monitoring radiating circuit plate on the temperature sensor interface, contain the Data Receiving modular converter on this circuit board, and wireless data transmission module, miniature emitting antenna is arranged on the circuit board, power interface is arranged on the circuit board, power supply is provided by electric battery, there is the encapsulation dividing plate to isolate between electric battery and circuit board, electric battery is installed in the battery box, and shell upper has gland bonnet, also has LED light on the circuit board, crystal oscillating circuit.
