The utility model simulates the capacitor to snap off a connecting circuit between the inner electrode and the outer electrode under the circumstance that the ineffective gas pressure is destroyed to detect the explosion proof effect of the explosion proof structure, not only the detection is simple, and the cost of the detection device is low, but also the detection is stable.
Description
Technical field
The utility model relates to a kind of pick-up unit that is used for detecting end cover type noinductive capacitor explosion-proof performance, the explosion-proof end cap pick-up unit of specifically a kind of capacitor.
Background technology
The blast resistance construction of end cover type noinductive capacitor is arranged on the end cap, its explosion-proof principle is: when the metallic film in the capacitor breakdown and the gasification after, gas in the housing expands, air pressure raises, be directed at cover plate and upwards heave distortion, break the connecting circuit between the inside and outside electrode, make capacitor metallic film inner core and external circuit disconnect, prevent that metallic film from further gasifying, reach explosion-proof purpose.Therefore, the explosion-proof performance of capacitor is mainly reflected in that can intrinsically safe circuit in time disconnect under the air pressure of setting.At present, the checkout equipment that generally uses is the explosion-proof senile experiment instrument of a kind of capacitor aborning, the gaseous tension when detecting capacitor the connecting circuit between the inside and outside electrode of explosion-proof end cap being broken under "on" position.Though more convenient with this Equipment Inspection, equipment is expensive, a common equipment needs more than 1,000,000 yuan, and equipment investment is higher; In addition, the capacitor finished product is detected, the measured capacitance device is damaged.
Summary of the invention
The purpose of this utility model provides the explosion-proof end cap pick-up unit of a kind of capacitor, and only the explosion-proof performance to the explosion-proof end cap of capacitor detects, and makes assay device structures simple, and is cheap.
The utility model is achieved in that it comprises monitor station, is arranged on inflator, tensimeter and detector switch on the monitor station; Described inflator is the container that a upper end is provided with gland, has pipeline to communicate with source of the gas and tensimeter respectively, the explosion-proof end cap lower edge coupling of upper port and institute's survey capacitor; Gland is threaded with inflator, and the centre of lid has the hole, and lower cover is fixed on the inflator openend with the explosion-proof end cap of capacitor in working order, exposes in two holes of electrode by gland of explosion-proof end cap, so that be connected with testing circuit.During detection, two interior electrodes of explosion-proof end cap are connected with lead, be placed on the inflator upper port then, and be fixed with gland, two external electrodes are connected with the two poles of the earth of metering circuit, the two poles of the earth of at this moment measuring power supply form path by explosion-proof end cap; Inflate in inflator then, break up to the circuit that explosion-proof end cap is connected outer pole, make metering circuit be disconnected, write down the shown force value of pressure gas this moment, this value is the explosion-proof pressure value of capacitor.
In order accurately to write down above-mentioned explosion-proof pressure value, the pipeline that source of the gas is communicated with inflator is provided with solenoid valve, and solenoid valve transfers gas source pipe to cut-off state by conducting when explosion-proof end cap opens circuit, so that operating personnel note the shown top pressure value of tensimeter.
The inflator openend is provided with the O-ring seal mounting groove, and under detected state, gland is tightly connected the lower edge of explosion-proof end cap by O-ring seal and inflator upper port.Can improve the sealing property of inflator under detected state like this.
The utility model is broken the explosion-proof effect that connecting circuit between the explosion-proof end cap internal and external electrode detects this blast resistance construction in advance by the pressurized air analog capacitor at the gaseous tension of damage inactivation, not only detects simply, and the pick-up unit cost is low, and detects stable.The explosion-proof effect of capacitor is determined that analysis provides facility extremely.Simultaneously, only need explosion-proof end cap is detected, detect cost and reduce greatly, shorten detection time greatly, effect stability.
