Abstract
The invention relates to a detection system, particularly to a gas on-line micro water content and density detection system. The detection system comprises a main air chamber, a joint, a sensor, a circuit board, a transducer shell, a wire connecting terminal and a waterproof joint. Two sides of the main air chamber are connected with the joint at fixed positions respectively; the upper end side is fixed with the sensor; the circuit board is connected with the sensor and arranged in the transducer shell; the circuit board passes trough the transducer shell to be connected with the wire connecting terminal by a circuit; the waterproof joint is connected with the top end of the transducer shell at a fixed position; a gas micro-water sensor, a gas density sensor and a gas temperature are arranged in the sensor; the joint is sealed with the main air chamber by a threaded seal and a plane seal; two circuit boards are provided; the detection circuit can be used fro detecting the micro water content, density and temperature of gas simultaneously; the sealing manner is safer; toxic gas is not leaked; and the effect is improved.
Description
Technical field
The present invention relates to a kind of detection system, the online little water-mass density detection system of especially a kind of gas.
Background technology
Current SF6 gas is with its superior insulation, arc extinction performance and be widely used in the primary cut-out and converting equipment of power industry, because descending, SF6 gas Moisture high UCL or density all can constitute grave danger to the safe operation of electrical equipment, its analyte has severe toxicity, in case leak and to cause very big injury to operating personnel, therefore must carry out regular moisture, the detection of density as the SF6 gas in the electrical equipment of insulation, arc-extinguishing medium to using SF6 gas.Existing tester it settle gas sensor generally can only measure a kind of parameter of SF6 gas, only adopt a kind of sealing means between air chamber and the sensor, therefore not only measure inconveniently, in the process of installing, leak air easily and cause great electric power safety accident.
Summary of the invention
Detect the deficiency that does not comprehensively reach operational hazards in order to overcome existing detection system, the invention provides the online little water-mass density detection system of a kind of gas.
The technical solution adopted for the present invention to solve the technical problems is: the online little water-mass density detection system of a kind of gas, comprise main gas tank, joint, sensor, circuit board, the transmitter shell, connection terminal and water joint, the both sides of main gas tank are connected with joint location respectively, the upper end is then fixed with sensor, circuit board links to each other with sensor, and place in the transmitter shell, circuit board utilizes circuit to pass the transmitter shell to link to each other with connection terminal, water joint and transmitter lid top are located by connecting, and sensor is built-in with the little water sensor of gas, gas density sensor and gas temperature sensor.
According to another embodiment of the invention, the sealing means that further comprises joint and main gas tank is the double seal mode of thread seal and flat seal.
According to another embodiment of the invention, comprise that further circuit board quantity is 2.
The invention has the beneficial effects as follows, use this testing circuit can detect little water, density and the temperature of gas simultaneously, and sealing means is safer, can not reveal toxic gas, has improved effect.
