How to make mechanical interlocking reliable, safe operation is also on-load switch difficulties.
Content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of structure novel, safe and reliable rotation
Rotatable double-fracture on-load switch.
In order to realize object above, this utility model be the technical scheme is that
A kind of rotary double-fracture on-load switch, including main shaft, the n that is arranged on main shaft touches to ground connection to moving contact, n
, to determining contact and n to metal arc-chute, wherein n is at least one for head, n；Described n to moving contact, n to grounding contact, n to surely touching
Head and n are respectively arranged to metal arc-chute in n in the plane of main shaft, are generally aligned in the same plane a pair of interior ground connection and touch
Head, determine contact and a pair of metal arc-chute for a pair symmetrical and respectively constitute and be grounded station, combined floodgate work all centered on main shaft
Position and separating brake station, make moving contact switch between ground connection station, combined floodgate station and separating brake station respectively by live spindle.
Further, also include to be arranged between adjacent plane and be used for the moving contact to adjacent plane, grounding contact, determine to touch
Head and metal arc-chute carry out the insulating barrier of dielectric separation.
Further, described grounding contact is respectively connected with the main copper bar of ground connection.
The beneficial effects of the utility model are: by the way of double-fracture, i.e. a pair on main shaft moves and touch this utility model
Head must determine contact simultaneously and contact after connection simultaneously just to can achieve combined floodgate with a pair, and determine contact at it and switch to combined floodgate station
When pass through arc-chute arc extinguishing.Such design makes switch can reach very strong connecting-disconnecting function.When as on-load switch and anti-close
Rated short circuit making current 63ka tetra- times at least can be closed and be not damaged by when closing earthed switch.In gb3804 regulation one
Still have after cut-offfing for 150 times sizable remaining threephase load limit drop-out current switch up to more than 2000a also have very high
Insulating properties there is when as disconnecting switch double-fracture dielectric level can reach industrial frequency withstand voltage 49kv impulse withstand voltage 85kv.This
Outer this utility model realizes moving contact in ground connection station, combined floodgate station and separating brake station by live spindle, correspondingly can be simple
Mutual switching between ground state, "on" position and gate-dividing state for the switch is realized by the operation of live spindle, its operation
Simply, vdiverse in function.

Specific embodiment
In conjunction with the drawings and specific embodiments, to this utility model, technical scheme required for protection is made further specifically
Bright.
Referring to accompanying drawing 1 to shown in accompanying drawing 4, a kind of rotary double-fracture on-load switch of the present embodiment, including main shaft 1, set
2, three pairs of grounding contacts 3, three of three pairs of moving contacts being placed on main shaft 1 are to determining contact 4 and three pairs of metal arc-chutes 5, wherein said
Grounding contact 3 is respectively connected with the main copper bar 31 of ground connection.In other embodiments moving contact 2, grounding contact 3, determine contact 4 and metal goes out
The logarithm of arc grid 5 can adjust according to the actual requirements it is only necessary to above-mentioned four logarithm unanimously.
2, three pairs of grounding contacts 3, three of three pairs of described moving contacts are to determining contact 4 and three pairs of metal arc-chutes 5 are respectively arranged
In three planes perpendicular to main shaft 1, in the present embodiment, for preventing from short cut with each other between adjacent plane, also in adjacent flat
Be provided between face for the moving contact 2 of adjacent plane, grounding contact 3, determine contact 4 and metal arc-chute 5 carries out insulation point
Every insulating barrier 6.
A pair of grounding contact 3 in being generally aligned in the same plane, determine contact 4 for a pair and a pair of metal arc-chute 5 with main shaft 1 is all
Centrosymmetry is distributed and respectively constitutes ground connection station, combined floodgate station and separating brake station, makes moving contact 2 respectively by live spindle 1
Switch between ground connection station, combined floodgate station and separating brake station.When a pair of moving contact 2 switches to ground connection station, respectively with one
Grounding contact 3 is contacted, now switch is in ground state；When a pair of moving contact 2 switches to combined floodgate station, respectively with a pair
Determine contact 4 to contact, now switch is in "on" position；When a pair of moving contact 2 switches to separating brake station, respectively with a pair of metal
Arc-chute 5 contacts, and now switch is in gate-dividing state.
By the way of double-fracture, that is, a pair of the moving contact 2 on main shaft 1 must determine contact 4 to the present embodiment simultaneously with a pair
Just can achieve after contact connects simultaneously and close a floodgate, and determine to pass through arc-chute arc extinguishing when contact 4 switches to combined floodgate station at it.So
Design make switch can reach very strong connecting-disconnecting function.At least can close when as on-load switch and anti-closed ground switch
Close rated short circuit making current 63 ka tetra- times and be not damaged by.Gb3804 regulation cut-off for 150 times after still have sizable remaining
Degree threephase load limit drop-out current switchs up to more than 2000a also to be had very high insulating properties and has when as disconnecting switch
Double-fracture dielectric level is had to can reach industrial frequency withstand voltage 49kv impulse withstand voltage 85 kv.In addition this utility model passes through live spindle 1
Realize moving contact 2 in ground connection station, combined floodgate station and separating brake station, correspondingly can realize simply by the operation of live spindle 1
Mutual switching between ground state, "on" position and gate-dividing state for the switch, its operation is simple, vdiverse in function.
