Abstract
A novel high and low pressure distributor bus infrared temperature monitoring device, which consists of a bus compartment, a bus, a thermoprobe, an infrared receiver, a current measurement device, a data processing and signal transmitting device, a movable contact, a static contact, a display screen and so on. The thermoprobe is arranged at the primary position of the bus. The probe is connected with the data processing and signal transmitting device, and the infrared receiver is arranged at a position corresponding to the data processing and signal transmitting device. The infrared receiver is connected with the display screen. The bus is connected with the movable contact and the static contact respectively. The device measures temperature accurately, solves the problem of the insulation of the prior high voltage components, reduces the cost of manufacture, is convenient to be installed and used, which solves a plurality of problems in the temperature measurement of the prior bus in China.
Description
One, technical field
The utility model relates to electric equipment manufacturing technology field, relates in particular to high-low voltage electric power distribution cabinet bus infrared temperature supervising device.
Two, background technology
The measurement of bus temperature in the past has two kinds:
1, direct temperature measurement, optical fiber transmission signal.Utilize optical fiber to convert the temperature signal of sensor acquisition to light signal, solved the problem of insulation like this, but the optical fiber price is higher, and the working power of sensor adopts battery, the mission life weak point.
2, the infrared thermography probe is closely measured bus temperature.This device has also solved the problem of insulation, but probe mounting requires high and the measuring accuracy difference is the defective of device.
Three, summary of the invention
The purpose of this utility model provides a kind of novel high-low voltage electric power distribution cabinet bus infrared temperature supervising device, by long-term production and research, measure the above defective that exists at bus temperature, developed the novel infrared temperature supervising device of this kind, this device is mainly by bus-bar room, connection bus, temperature probe, infrared receiving device, and connection cable, current measurement device and power supply, data processing and transmission telltale, static contact, moving contact, display screen are formed.In bus-bar room; be provided with many and connect bus; on the bus at main position; be provided with temperature probe; temperature probe and data processing and send that the telltale connection bus is indoor to be provided with and to send the corresponding infrared receiver of telltale; it is connected with display by connection cable; the two ends of bus are connected with static contact with moving contact respectively; this device is directly to measure the bus temperature signal with temperature measurement probe on bus; signal is processed into infrared signal after testing and spreads out of; receiving trap receives after signal is changed and passes to display that display shows to be measured temperature and according to function corresponding output alarm is set; the instruction of action such as power-off protection.Adopt the beneficial effect of this device have following some:
1, directly measures.Guaranteed the precision of measuring.Also be convenient to simultaneously the installation of measurement mechanism.
2, Infrared Transmission detection signal.Solved the Insulation Problems of operation circuit and primary circuit mesohigh element.
3, the working power of measurement mechanism is directly provided by the current measurement coil of measurement mechanism.Solved the Insulation Problems of external power supply lead-in wire.
4, the Infrared Transmission mode is adopted in the transmission of measuring-signal, has cancelled the optical fiber in the Optical Fiber Transmission in the general temperature survey, has reduced the manufacturing cost of device.
High-low voltage electric power distribution cabinet infrared temperature supervising device has solved that the measuring accuracy that exists in the domestic existing bus temperature measurement mechanism is poor, the cost height, has installed and used problems such as inconvenience.
