Description
Technical field
The utility model relates in industrial power distribution the isolating switch as auxiliary facility, but particularly a kind of collection dropout type is isolated the solid insulation isolating switch of operating mechanism and tubulose gear unit.
Background technology
Isolating switch is to use maximum a kind of electrical equipment in the high-voltage switch electric appliance, and the operation principle of itself is fairly simple, but because use amount is big, functional reliability requires high, and is all bigger to the influence of design, foundation and the safe operation of electric substation, power plant.
At present general isolating switch adopts traditional disconnecting link formula isolating switch mostly, in today of scientific and technical fast development, and the technical problem that disconnecting link formula isolating switch has exposed itself and had; Existing high voltage isolator utilizes the round steel welding to form main shaft, left and right sides operating stationary; Switch operation mechanism be failure to actuate for a long time can cause close, mechanism is dumb during the broaching tool lock, under serious area of filth or over-voltage condition, flashover can take place; Porcelain vase bursts, and damage disconnecting link equipment, and the disconnecting link contact portion that is in operation is overheated; Owing to tighten superstructure loosening, open one's mouth and close to such an extent that sternly do not cause overheated or edge of a knife melting welding, in addition; Disconnecting link formula isolating switch takes up room greatly because of its structure, and inconvenience is installed, and the stability of action and long playing reliability all exist certain defective comparatively speaking.
Along with science and technology development, general existing problem of disconnecting link formula isolating switch and defective must solve and improve at present.
The utility model content
The technical problem that the utility model will solve provides a kind of stable performance, reliable transmission, tight, easy for installation, the daily solid insulation isolating switch that need not safeguard, not receive running environment to influence of contact.
The technical scheme that adopts is:
The solid insulation isolating switch is mainly isolated operating mechanism by dropout type and the tubulose gear unit is formed, and promptly guarantees can not continue motion after the isolation moving contact puts in place, and assurance is isolated the steady transmission of moving contact and contacted with isolation the tight of fixed contact again.
Said dropout type is isolated operating mechanism, be by worm gear case as supporting construction, inside is equipped with isolated operation flange, clutch flange, transmission worm screw, transmission worm gear and bearing pin.Clutch flange one end is sleeved on the isolated operation flange; The other end is sleeved on the transmission worm screw, and the isolated operation flange is contained on the worm gear case through rolling bearing, is fixed with ratchet with detent pin on the clutch flange; Using torsion spring resets to ratchet; Bearing pin passes worm gear case and links to each other with the interlock tooth bar, promptly play fixation simultaneously again the distich carry-over bar play the effect of guiding, in the same side of the tooth bar that links the key axle is installed; This key axle is connected with the transmission worm gear after installing worm gear case, the teeth interlock of key axle teeth and interlock tooth bar.
Said tubulose gear unit is made up of travelling gear, adapter sleeve, insulation screw mandrel, isolation moving contact, fixed contact; The center that isolates moving contact is provided with through hole; One end is fixedly connected with screw; Screw is designed to helical structure, and making has the insulation of helical structure screw mandrel rotation set on it equally, and an end of insulation screw mandrel is fixedly connected on the travelling gear through adapter sleeve.
The utility model stable performance, reliable transmission, contact are tight, security of operation, easy for installationly, daily need not safeguard, not influenced by running environment.
The characteristics of the utility model are:
1, worm gear case is made by aluminium alloy extrusions, and it is intensity high (can reach the intensity of 45# steel) not only, and (being 1/3 weight of steel) in light weight.
2, (about 15 circles) dropout type was isolated the ratchet dropout of operating mechanism after the isolation moving contact put in place, made mechanism be in sky and closed state, prevented that the contact area that causes from reducing and device damage.
3, be designed with a deciliter direction board on the interlock tooth bar, isolating switch carried out the indication of " branch ", " closing " lock along with the interlock transmission of teeth.
In case 4 operating grips insert the isolated operation flange of dropout type isolation operating mechanism and shake in the process of closing or shaking branch; Can't extract operating grip from the isolated operation flange, avoid the solid insulation isolating switch deciliter damage of equipment and the safety of personal equipment of causing not in place.
5, the main body of tubulose moving contact is a hollow copper tubing, and surface area is big, and ampacity is big; Conventional relatively rectangle moving contact (rectangle busbar), its conductive surface electric current distribution is even, and because the copper pipe middle part is hollow; Hot-air can form cross-ventilation in conductor inside, and radiating condition is good.
6, fixed contact is made up of three contacts, is respectively grounding contact, middle contact, insulating contact, makes isolating switch be divided into two positions and promptly isolates and close the position and isolate to divide position (ground connection is closed the position).
7, tubulose moving contact and fixed contact junction adopt the watchband fingertip to fit tightly, and guarantee enough contacts area.
The insulation screw mandrel of the isolating switch that 8, constitutes, isolation moving contact, fixed contact are three covers and corresponding with A, B, the C three of alternating current respectively; One of them travelling gear is contained in dropout type through adapter sleeve isolates on the transmission worm screw of operating mechanism; Drive the action transmission of adjacent travelling gear, accomplish A, B, C synchronous branch, the combined floodgate of three cover isolating switches mutually.
Need to prove: under the prerequisite of principle that does not change the utility model and design, change of being made or distortion all belong to the protection range
of the utility model.
