Abstract
The utility model discloses an intermittent discharge detection device of a high-voltage distribution box and belongs to a safety monitoring device suitable for an electric power distribution box. The device comprises a transmitting part and a receiving part which are suppied with power by a power circuit, wherein the transmitting part is composed of an electronic ballast and an ultraviolet tube UV, the input end of the receiving part is provided with a photoelectric sensor VD with an ultraviolet filter; and the sensor VD sends an ultraviolet detection signal to a comparison circuit through a signal detection circuit and a signal amplification circuit, compares the signal with the level value of a threshold setting circuit, then outputs the signal to a liquid crystal display, and transmits a warning signal by a warning output circuit. When a certain component in the high-voltage distribution box has slight intermittent high-voltage discharge phenomena caused by dust accumulation, moist air, and the like, ozone is generated due to air ionization and the device detects the concentration of the ozone generated by high-voltage discharge in time by utilizing the variable of the received ultraviolet radiation and sends an early warning signal, so that maintainers can find the accident potential in time to take cleanup measures as soon as possible, and thus ensuring security of the power supply.
Description
Technical field
The utility model belongs to the applicable safety monitoring assembly of electric power distributing cabinet.
Background technology
High voltage power distributing cabinet at power-supply unit is inner, due to the accumulation of narrow space, dust and the reason such as there was dampness in the air, can produce slight high pressure batch electric discharge phenomena between some parts or wiring, if can not in time find, in the course of time the incrustation of discharge generation can get more and more, electric discharge phenomena will increase the weight of gradually, the most at last equipment be caused damage.Therefore, in time finding slight high pressure batch electric discharge phenomena in high voltage power distributing cabinet, clear up as early as possible maintenance, is an important process of assurance equipment normal operation.
Summary of the invention
The purpose of this utility model is a kind of pick-up unit that can in time find slight effluve phenomenon in high voltage power distributing cabinet of design.
The technical solution of the utility model is: this device is divided into and transmits and receives two parts, by a power circuit power supply, wherein radiating portion is comprised of electric ballast and quartz burner UV, the input end of receiving unit be one with the photoelectric sensor VD of ultraviolet filtering mirror, this sensor VD delivers to comparator circuit through signal deteching circuit and signal amplification circuit with the UV detection signal, compare with the level value of threshold value setting circuit, then output signal is to liquid crystal display, and by caution output circuit emission alarm signal.
The beneficial effects of the utility model: when certain parts in high voltage power distributing cabinet produce slight high pressure batch electric discharge phenomena due to the dust accumulation with reasons such as there was dampness in the air, air ionization will produce ozone, this utility model utilization receives ultraviolet variable and the ozone concentration that effluve produces in time detected, send early warning signal, make the maintainer in time find accident potential, take as early as possible the cleaning measure, ensure power supply safety.
Description of drawings
Accompanying drawing 1 is the utility model circuit block diagram.
Embodiment
As shown in Figure 1, this device is divided into and transmits and receives two parts, and by a power circuit power supply, power circuit is input AC 220V, and output has the 5V direct supply of electric ballast working power and receiving circuit.
The transmitting terminal of this device and receiving end are arranged on respectively two positions in high voltage power distributing cabinet, and can not there be the parts that intercept light the centre, to guarantee detection sensitivity.Wherein radiating portion is comprised of electric ballast and quartz burner UV, the input end of receiving unit be one with the photoelectric sensor VD of ultraviolet filtering mirror, this sensor VD detects the ultraviolet signal by signal deteching circuit, deliver to comparator circuit after by signal amplification circuit, detection signal being amplified, level value with the threshold value setting circuit compares again, then outputs to liquid crystal display and shows Monitoring Data.
When certain parts in high voltage power distributing cabinet produce slight high pressure batch electric discharge phenomena due to the dust accumulation with reasons such as there was dampness in the air, the air ionization phenomenon will produce ozone, airborne ozone has intercepted ultraviolet, causing this device to receive ultraviolet variable changes, comparator circuit in time detects the change amount of UV detection signal, output to liquid crystal display, and by caution output circuit emission alarm signal, make the maintainer in time find accident potential, take as early as possible the cleaning measure, ensure power supply safety.
The electric ballast that this device uses and quartz burner UV and ultraviolet filtering mirror and photoelectric sensor VD are the commercially available prod, have Multiple Type to select, and repeat no more herein.
