Description
Technical field
The invention belongs to electric equipment operation performance monitoring field, be particularly useful for air insulation switch cubicle compartment interior electrified body and discharge the ozone amount variation monitoring caused.
Background technology
Air-insulated switch cubicle the electric equipments such as circuit breaker, isolating switch, earthed switch, bus, lightning arrester are worn long cabinet sleeve pipe, supporting insulator combination be encapsulated in metal shell.General more in the indoor application of 10kV, 35kV grade.Often be divided into withdraw-type and fixed.
Because consumption is large, workmanship, running environment, testing conditions and inspection policies, accident is more.Separation structure and electric two class defects, wherein the insulation of electric information with heating defect accounting more than 3 one-tenth.
Detection for heating has the practical technique such as wireless temperature measurement, infrared window at present, and the current charged mode of the detection for electric discharge is in the majority, and on-line monitoring is also the extension of live detection technology, i.e. TEV and ultrasonic technique substantially.
Aerial discharge has ozone and produces, due to pattern and the service conditions of air insulation switch cubicle, the ozone that compartment interior produces because of electric discharge can retain certain hour in a relatively airtight space, in addition its molecular weight is greater than the main content gas oxygen of air and nitrogen, has gathering in cell bottom.
The electric discharge composition detection method of similar SF6 gas, electric discharge monitoring for air insulation switch cubicle can based on ozone parameter, by communication, realize the electric discharge value on-line monitoring close with wireless temperature measurement technology, but active nature and the life problems of ozone sensor should be considered.
Based on above-mentioned situation and present situation, propose a kind of air insulation switch cubicle compartment ozone content checkout gear thinking, and be achieved by technological means, to solve the practical problem of run switch cabinet electric discharge monitoring.
Summary of the invention
Air-insulated inside switch cabinet electric discharge is carried out in air insulation environment, generally have ozone to produce, the ozone produced because of electric discharge based on compartment interior can retain certain hour in a relatively airtight space, in addition because its molecular weight is greater than the main content gas oxygen of air and nitrogen, ozone can be assembled in cell bottom, proposes the technical thought being carried out pilot switch cabinet compartment interior discharge scenario by the on-line monitoring of ozone content.The present invention proposes the formation of ozone detecting unit, put shelter in the inner and the shelter layout at switch cubicle compartment.
The present invention is realized by following technical proposal.
A kind of air insulation switch cubicle compartment ozone content checkout gear, feature of the present invention is: comprise shelter and be located at the ozone detecting unit in shelter, wherein: shelter is placed in bottom the outer panels of air insulation switch cubicle compartment, shelter is through the perforate inside flush switch cabinet compartment of outer panels, the movable hatch door of shelter is provided with draw ring to realize the unidirectional folding of movable hatch door, the movable hatch door of shelter flushes with the outer panels of switch cubicle compartment, and 5 faces that shelter is embedded to switch cubicle compartment in all the other except movable hatch door have gap; Ozone detecting unit connects power module respectively by transducer, input and processing unit, wireless transmitter module and forms, and wherein the power supply of power module is provided by 220V cabinet power supply.
