It is as follows to address the above problem existing technical method at present: adopt to measure components and parts and be installed in the Surge Protector, the physical parameter of surge protective device is detected, and export measurement and control unit analysis to, show, control etc.Above technical method still has problems: 1, measure components and parts and be installed in the Surge Protector, easily cause when surge current is released measuring the interference or the damage of components and parts, make measurement result inaccurate, cause false alarm, misoperation; 2, the selected measurement component parameter kind of different surge protective devices has nothing in common with each other, and makes type selecting complexity in the product design manufacture process; 3, measure components and parts and surge protective device and independently be installed in the Surge Protector, take the inner space, line connecting relation complexity, fault point increase, and installation procedure increases, difficulty increases.
The utility model content
In order effectively to overcome the above problems, the utility model proposes a kind of surge protective device with measuring ability.
The purpose of this utility model provides a kind of surge protective device with measuring ability; can realize the surge protection function and detect output function; in physical quantitys such as the temperature that electric current, surge protective device produced, infrared ray, discharge arc light and space electric field or the magnetic field that can pass through surge protective device or these physical quantitys one or more detect in real time and export measurement and control unit (11) to by detection terminal (7) and carry out analyzing and processing; surge safeguard function and measuring ability collection are one, are convenient to install select for use.
The utility model is realized by the following technical solutions: the surge protective device of band measuring ability is mainly by surge protective unit (1), sensor unit formations such as (2); Surge protective unit (1) is encapsulated in the same encapsulating housing (4) with sensor unit (2); be installed in the Surge Protector (12); surge protection terminal is connected on the binding post of Surge Protector (12), and detection terminal (7) is connected to the measurement and control unit (11) of Surge Protector (12).
Surge protective unit (1) is connected on the binding post of Surge Protector (12) by surge protection terminal; constitute the surge protection loop; sensor unit (2) is connected to measurement and control unit (11) by detection terminal (7); constitute and detect loop, the surge protection loop electrical isolation at the detection loop at sensor unit (2) place and surge protective unit (1) place.Surge protective unit (1) can be any device or the circuit that can realize the surge protection function, as piezo-resistance, discharge tube etc.Parameter characteristic when sensor unit (2) damages according to the deterioration of surge protective unit (1) mates, sensor unit (2) can be a kind of transducer or sensor combination, one or more in physical quantity such as the temperature that electric current, surge protective device produced, infrared ray, discharge arc light and space electric field or the magnetic field that can pass through surge protective device or these physical quantitys.Sensor unit (2) can be provided with internal or external signal conversion module (3), and detected information is converted into numeral or analog signal output.Sensor unit (2) determines according to the transducer kind with the connected mode of surge protective unit (1), for example: current sensor adopts the form of electric current loop to be installed on the lead of surge protective unit (1) surge current path, and temperature sensor is pressed close to surge protective unit (1) and installed.
Advantage of the present utility model is: surge protective unit (1) and sensor unit (2) are encapsulated in the same housing, have possessed surge protection and measuring ability simultaneously; Surge protective unit (1) and sensor unit (2) have carried out parameter matching, need not to be configured selection again; With the electrical isolation in the surge protection loop at the detection loop at sensor unit (2) place and surge protective unit (1) place, prevent to detect the loop and sensor unit (2) is subjected to the interference that surge current is magnetic field; Be installed in the Surge Protector (12), easy for installation, and reduced to take up room, reduce the fault point, efficiently solve the problem of existence noted earlier.
