Description
Technical field
The present invention relates to field of mechanical technique, more particularly to a kind of handcart type breaker contact engagement visual testing platform
Frame.
Background technology
High-tension switch cabinet refers to be used for play break-make, control in power system generating, transmission of electricity, distribution, electric energy conversion and consumption
Or the effect such as protection, high-tension switch cabinet is by electric equipment products of the voltage class in 3.6kV~550kV are made, and high voltage isolator is with connecing
Ground switch, high voltage load switch, high pressure automatic reclosing and sectionaliser, high-voltage actuating mechanism, high voltage explosion-proof power distribution device and high pressure
Several major classes such as switch cubicle.
High-tension switch cabinet has the functions such as aerial inlet-outlet line, cable incoming-outgoing wire, bus contact.Be primarily adapted for use in power plant,
The various different fields such as transformer station, petrochemical industry, metallurgical steel rolling, industry light industry textile industry, industrial enterprise and residential quarters, skyscraper.
" the relevant requirement of standard, by cabinet and breaker two that high-tension switch cabinet should meet ac metal closing switch gear
Most of composition, cabinet are made up of housing, electric elements (including insulating part), various mechanisms, secondary terminals and line etc..
High-tension switch cabinet is divided into withdraw-type (handcart-type) and fixed by breaker mounting means；It is divided into family by infield
It is interior and outdoor；It can be divided into metal enclosed armoured switch cabinet, metal enclosed spaced switch cabinet, metal enclosed case by cabinet body structure
Formula switch cubicle and the major class of open type switch cubicle four.
Indoor, metal enclosed armored, the high-tension switch cabinet with handcart type breaker, commonly referred to as armored withdraw type exchange
Metal enclosed switchgear (hereinafter referred to as switch cubicle), its common voltage grade is including 10kV, 20kV, 35kV etc..It is main to use
In power 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 receiving and distributing electric energy, and control, protection and monitoring are carried out circuit.
Switch cubicle is by the cabinet fixed and can remove part (handcart) two large divisions and forms.Part (handcart) can be removed the bottom of by
Disk and breaker body composition, propulsive mechanism are arranged on inside chassis.Chassis two sides are respectively equipped with 2 wheels, built-in needle roller axle
Hold so that handcart light and flexible when promoting, pulling out.Handcart be divided into circuit breaker cart, isolated hand car, 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, including：Open circuit
Device room, bus-bar room, cable vault and control room.Dividing plate between the shell of cabinet and each functional unit is bent using aluminizing zine plate
Form.The static contact of breaker is installed in the cabinet side that breaker chamber is fixed, part (handcart) side can be removed and be provided with
The moving contact of breaker (Mume flower contact) of pairing, the two is to occur, in the breaker chamber portion of closing, can not intuitively observe when engaging
The depth of engagement of the two.
High-tension switch cabinet operates, and wheelbarrow switch moves to operating position, hand wheelbarrow switch from testing position, and moving contact enters
Started counting up during static contact, until shaking engagement (insertion) depth for this trip of operating position, being dynamic/static contact.
The depth of engagement of handcart type breaker dynamic/static contact, 10kV~35kV handcart-types are had to check for after switch cubicle newly installation
The depth of engagement of breaker dynamic/static contact is 15~30mm, and measurement size must be extremely accurate to grade.Traditional measuring method is：
A small amount of vaseline is applied on static contact, handcart is pushed into running position, then handcart is pulled out outside cabinet, handcart sound is then measured and touches
The impression on static contact is stayed in during head engagement.Wheelbarrow switch, the hand process to operating position be can't see, and hand is also touched not
Arrive, this original measurement method can only be used, sized data error is very big, especially in summer high-temperature season, temperature 35 DEG C with
Vaseline liquefies when upper, does not see impression, or even without impression, checked and accepted to in-site measurement and bring very big difficulty, can not ensure handcart
The accurate of formula breaker dynamic/static contact, reliable contacts (must be under bus bar side and feeder line side power-off condition), and easily error.
Lu Zhi brightness et al. proposes a kind of closing armouring high-voltage switch cubicle handcart formula contact of breaker depth of engagement measurement dress
Put (application for a patent for invention number：201410341258.8/ utility application number：201420396190.9), including six sets
Displacement transducer, six sets of displacement transducers are respectively in 6 moving contacts of A, B, C three-phase loaded on high-voltage switch cubicle handcart formula breaker
In portion's counter sink, power line and signal wire are drawn in the border space through moving contact, and the space through handcart type breaker is drawn
High-tension switch cabinet, it is connected with data processing equipment, data processing equipment is connected to display device.Can conveniently, accurately it measure
Handcart type breaker contact engagement depth.But in the design and manufacturing process of instrument, it is fixedly mounted for adjustment displacement transducer
For scheme, it is necessary to frequently run high-tension switch cabinet erecting bed, start stop switch cabinet also influences electric power regular supply, cumbersome, and wave
Take manpower and materials.
The content of the invention
The brief overview on the present invention is given below, to provide the basic reason on certain aspects of the invention
Solution.It should be appreciated that this general introduction is not the exhaustive general introduction on the present invention.It is not intended to determine the key of the present invention
Or pith, nor is it intended to limit the scope of the present invention.Its purpose only provides some concepts in simplified form, with
