Description
Technical field
The present invention relates to field of mechanical technique, particularly a kind of depth of engagement method of testing of handcart type breaker contact engagement stand.
Background technology
High-tension switch cabinet refers to for electric system generating, transmission of electricity, distribution, electric energy conversion and plays the effects such as break-make, control or protection in consuming; high-tension switch cabinet is by making the electric equipment products of electric pressure at 3.6kV ~ 550kV; high voltage isolator and grounding switch, high voltage load switch, high pressure automatic reclosing and sectionaliser, several large classes such as high-voltage actuating mechanism, high-voltage explosion-proof power distribution equipment and high-tension switch cabinet.
High-tension switch cabinet has the functions such as built on stilts line, cable incoming-outgoing wire, bus contact, is mainly applicable to generating plant, transformer station, petrochemical complex, metallurgical steel rolling, industry light industry textile industry, industrial enterprise and the various different places such as residential quarters, skyscraper.
High-tension switch cabinet should meet ac metal closing switch gear, and " relevant requirements of standard, is made up of cabinet and isolating switch two major part, and cabinet is made up of housing, electric elements (comprising insulating part), various mechanism, secondary terminals and line etc.
High-tension switch cabinet is divided into withdraw-type (handcart-type) and fixed by isolating switch mounting means; Be divided into indoor and outdoor by infield; The large class of metal enclosed armoured switch cabinet, metal enclosed spaced switch cabinet, metal enclosed box switch cubicle and open type switch cubicle four can be divided into by cabinet body structure.
The high-tension switch cabinet of indoor, metal enclosed armored, band handcart type breaker, be commonly referred to armoured removable type alternating (hereinafter referred to as switch cubicle), its common voltage grade comprises 10kV, 20kV, 35kV etc.Be mainly used in generating plant, transformer station, medium and small generator power transmission, industrial and mineral enterprises and institutions distribution and Large-scale High-Pressure motor starting etc.For accepting and distributing electric energy, and control, protection and monitoring are carried out to circuit.
Switch cubicle is by the cabinet fixed and can remove parts (handcart) two large divisions and form.Can remove parts (handcart) to be made up of chassis and breaker body, propulsive mechanism is arranged on inside chassis.2 wheels are respectively equipped with in two sides, chassis, in-built needle bearing, make handcart light and flexible when propelling, pull-out.Handcart is divided into circuit breaker cart, isolation handcart, voltage mutual inducer trolley, earth handcart etc.According to the function of electrical equipment in cabinet, cabinet dividing plate is divided into four different functional units, comprising: breaker chamber, bus-bar room, cable vault and metering house.Dividing plate between the shell of cabinet and each functional unit all adopts aluminizing zine plate to bend and forms.The static contact of isolating switch is installed in the cabinet side that breaker chamber is fixed, the moving contact of breaker (Mume flower contact) that parts (handcart) side is provided with pairing can be removed, occur in closed breaker chamber portion during the two engagement, cannot the depth of engagement of both direct vision.
High-tension switch cabinet operates, and wheelbarrow switch moves to working position from testing position, hand wheelbarrow switch, starts counting, until shake this LAP to working position, be engagement (insertion) degree of depth of dynamic/static contact when moving contact enters static contact.
Switch cubicle must check the depth of engagement of handcart type breaker dynamic/static contact after newly installing, the depth of engagement of 10kV ~ 35kV handcart type breaker dynamic/static contact is 15 ~ 30mm, and measurement size must be accurate to grade.Traditional measuring method is: on static contact, be coated with a small amount of vaseline, handcart is pushed into run location, then pulls out outside cabinet by handcart, stays the impression on static contact when then measuring the engagement of handcart dynamic/static contact.Wheelbarrow switch, the hand process to working position be can't see, hand also touch less than, this original measurement method can only be adopted, dimensional data error is very large, especially in summer high-temperature season, when temperature is more than 35 DEG C, vaseline liquefaction, does not see impression, even without impression, check and accept to in-site measurement and bring very large difficulty, accurate, the reliable contacts (must under bus bar side and feeder line side power-off condition) of handcart type breaker dynamic/static contact cannot be ensured, and easily make mistakes.
The people such as Lu Zhihui propose a kind of closed armouring high-voltage switch cubicle handcart formula contact of breaker depth of engagement measurement mechanism (application for a patent for invention number: utility application No. 201410341258.8/: 201420396190.9), comprise six cover displacement transducers, six cover displacement transducers are loaded on the A of high-voltage switch cubicle handcart formula isolating switch respectively, B, in the inner counter sink of C three-phase 6 moving contacts, power lead and signal wire are drawn in the space, border of moving contact, and draw high-tension switch cabinet through the space of handcart type breaker, be connected with data processing equipment, data processing equipment is connected to display device.Can facilitate, measure handcart type breaker contact engagement depth accurately.But in the design and manufaction process of instrument, be adjustment displacement transducer fixed installation scheme, need frequent race high-tension switch cabinet erecting stage, start stop switch cabinet also affects electric power regular supply, cumbersome, and wasting manpower and material resources.
