Description
Technical field
The present invention relates to a kind of test handcart of switchgear, belong to electric power switchgear assembly technical field.
Background technology
Kyn28a-12 armored central enclosed AC metal switch apparatus (hereinafter referred to as middle-placed switch cabinet), are that one kind is applied to
The complete power distribution equipment of 3.6 ~ 24kv three-phase alternating current 50hz power system, is mainly used in power plant, medium and small generator power transmission, work
Ore deposit enterprises and institutions distribution, the electric substation of power system are subject to power transmission and Large-scale High-Pressure Motor Control etc..Middle-placed switch cabinet has following knot
Structure feature: a, completely adopt metal armouring, separate completely between each compartment.B, cabinet shell tightness are high, effectively prevent equipment to be subject to each miscellaneous
Thing, animal invasion, up to ip4x, between compartment, degree of protection is up to ip2x for shell protection grade.C, vacuum circuit breaker and its operation
Mechanism only needs to safeguard on a small quantity, and overhauls conveniently.D, rational in infrastructure, five anti-mechanisms are perfect, and equipment is safe and reliable to operation, maintenance side
Just quick.E, multiple domestic or joint choppers can be adapted to, such as vs1, vd4,3ah2 etc., change that chopper is simple, handcart is mutual
Transsexual good.In view of above advantage, middle-placed switch cabinet progressively replaces the cabinet type such as gg1a, kgn, xgn at home, becomes 3.6 ~ 24kv
The main product of set controller switching equipment.

The cooperation of head needs to consider following factor: when 1, handcart enters operating position, the effective contact area coinciding of dynamic and static contact will
Ask.2nd, when handcart enters operating position, static contact and handcart contact arm must not occur mechanical interference.3rd, handcart exits to testing position
When, the air clearance of static contact and metal dampers should meet the requirement of safe distance.Summary factor, generally suggestion are dynamic and static
Contact Bite size between 15 ~ 25mm, in particular cases should premised on meeting above-mentioned 3 conditions, carry out Size calculation and
Check.
Before equipment making dispatches from the factory well, tackle this significant dimensions and test, but in view of the construction featuress of middle-placed switch cabinet, move,
Static contact is hidden in the contact box of handcart room it is impossible to observe directly the calculating requirement whether Bite size meets 15 ~ 25mm,
Generally inspection this size each complete set of equipments producer has thought a lot of methods, 1, conductive paste or vaseline are smeared on static contact, handcart pushes away
Retreat out after operation, the vestige left is observed on static contact to estimate Bite size.2nd, pass through to shake handcart by propelling resistance
Size estimating Bite size.3rd, observation port is opened by cabinet side, estimate estimation Bite size with torch for illumination.But on
All there is the problems such as inspection size is inaccurate, and error is big, and operating process implements inconvenient in method of stating.
In view of this, the present inventor is studied to this problem, specially develops one kind and is used for checking middle-placed switch cabinet dynamic and static
Whether the test handcart of contact Bite size, the size Selection for check valve cabinet contact and installation meet the requirements.
