Description
Technical field
The present invention relates to a kind of sealing armouring high-voltage switch cubicle handcart formula contact of breaker depth of engagement measurement mechanism.
Background technology
High-tension switch cabinet refers to for electric system generating, transmission of electricity, distribution, electric energy conversion and has consumed the effects such as break-make, control or protection; 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.Mainly be applicable to various different of generating plant, transformer station, petrochemical complex, metallurgical steel rolling, industry light industry textile industry, industrial enterprise and residential quarters, skyscraper etc.
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 parts, 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; Can be divided into metal enclosed armoured switch cabinet, the metal enclosed box switch cubicle of metal enclosed spaced switch Gui ﹑ and the large class of open type switch cubicle four by cabinet body structure.
Indoor, metal enclosed armored, high-tension switch cabinet with handcart type breaker, be commonly referred to armoured removable type alternating (being designated hereinafter simply as switch cubicle), and 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 circuit is carried out to control, protection and monitoring.
Switch cubicle is by the cabinet of fixing and can remove parts (handcart) two large divisions and form.Can remove parts (handcart) and 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, and in-built needle bearing makes handcart light and flexible in the time advancing, 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 is divided into four different functional units with dividing plate, comprising: breaker chamber, bus-bar room, cable vault and metering house.Dividing plate between the shell of cabinet and each functional unit all adopts the bending of aluminizing zine plate to form.The static contact of isolating switch is installed in fixing cabinet one side of breaker chamber, can remove the moving contact of breaker (Mume flower contact) that parts (handcart) side is provided with pairing, when the two engagement, be the breaker chamber portion that occurs in sealing, cannot intuitively observe the depth of engagement of the two.
High-tension switch cabinet operation, wheelbarrow switch moves to working position from testing position, and hand wheelbarrow switch starts counting when moving contact enters static contact, until shake this LAP to working position, be engagement (insertion) degree of depth of dynamic/static contact.
The depth of engagement that must check handcart type breaker dynamic/static contact after the new installation of switch cubicle, the depth of engagement of 10kV～35kV handcart type breaker dynamic/static contact is 15～30mm, 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 handcart is pulled out outside cabinet, stay the impression on static contact while 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, can only adopt this original measurement method, dimensional data error is very large, especially in summer high-temperature season, temperature is vaseline liquefaction more than 35 DEG C time, does not see impression, even without impression, check and accept and bring very large difficulty to in-site measurement, cannot ensure handcart type breaker dynamic/static contact accurately, reliable contact (must under bus bar side and feeder line side power-off condition), and easily make mistakes.
