Background technology
Existing isolating switch all is to utilize the power set of motor one class directly to drive the action of cranking arm of insulation rotating shaft operate high pressure side, thereby realizes that by cranking arm divide-shut brake moves.For example: 123 of Alstom (China) Investment Co., Ltd (ALSTOM) production---the scissor isolating switch of 550KV is exactly this structure.This isolating switch is because what adopt is the mode of motor direct-drive, and speed is relatively slow at first starting for motor, improve speed gradually, and power switch requires higher just-off speed in divide-shut brake.Be that the direct drive-type isolating switch of motor direct-drive formula or other forms of machinery all exists above defective inevitably.In addition, it is that two gear locking phases by direct engagement are to rotating the relative motion that realizes cranking arm that two of this scissor isolating switch crank arm, because the spacing between two gears is too little, the two maximum anglecs of rotation of cranking arm are 90 °, two crank arm when clamping bus under the effect of huge profit still can the open trend in oriented both sides, and can upwards impact bus in the moving contact contact fixed contact on the top of cranking arm, long-term use also influences the mechanical endurance and the stability of operating mechanism.
Summary of the invention
The purpose of this utility model provides a kind of have higher just-off speed, manual divide-shut brake, the back contact that the closes a floodgate energy-storage isolating switch that can not become flexible naturally.
For achieving the above object, the utility model adopts following technical scheme:
Energy-storage isolating switch described in the utility model comprises base, be fixedly mounted on the transmission case body on base top, gear box, be connected with insulation column and insulation rotating shaft between transmission case body and the gear box, left gear is installed in the gear box, right gear, left gear, right gear connect respectively a left side crank arm and the right side crank arm, the lower end and the drive unit of insulation rotating shaft are in transmission connection, the upper end be equipped with bevel gear and with gear box in gears engaged, it is characterized in that: transmission case body comprises the energy-stored spring case that is in transmission connection with drive unit, bistable commutator, be provided with support in the energy-stored spring case, by Bearing Installation transverse axis is arranged on the support, the one end fixed installation energy storage brake disc of transverse axis, supporting disk in the other end fixed installation spring, other has the outer supporting disk of spring to be contained on the support by bearing holder (housing, cover), disc spring one end is fixed on the interior supporting disk of spring, and the other end is fixed on the outer supporting disk of spring; The outer supporting disk of spring is in transmission connection by energy storage worm and gear device and power set; Transverse axis is by the power shaft of shaft joint connection bistable commutator, and the output shaft of bistable commutator is in transmission connection by commutation worm and gear device and insulation rotating shaft.On the commutation worm screw divide-shut brake brake disc is installed.
Between left gear and the right gear transition gear is installed, the quantity of transition gear is even number.
The power shaft of bistable commutator, output shaft, transition axis by Bearing Installation in casing, wherein be installed with power shaft combined floodgate gear and power shaft constant mesh gear on the power shaft, be slidingly fitted with output shaft doubly-linked gear by spline keyway mechanism on the output shaft, be installed with transition axis constant mesh gear and transition axis separating brake gear on the transition axis, power shaft constant mesh gear and the engagement of transition axis constant mesh gear, output shaft doubly-linked gear on output shaft in the slippage respectively with power shaft combined floodgate gear or transition axis separating brake gears engaged, connect shift fork on the output shaft doubly-linked gear.
The shift fork that connects on the output shaft doubly-linked gear is fixedly connected on the shifting fork bar, shifting fork bar and bistable permanent magnetic switch are in transmission connection, be provided with output shaft in the shell of described bistable permanent magnetic switch, it is overhanging that output shaft passes the end cap at shell two ends, its front end is connected with shifting fork bar, be fixed with iron core on the output shaft, the arranged outside of iron core has permanent magnet, permanent magnet is fixedlyed connected with shell, the two ends of permanent magnet respectively are provided with set of pulses coil, the contact site of output shaft and shell is set with antimagnetic axle sleeve, has inwardly protruded end cap magnetic boots on the shell around the antimagnetic axle sleeve, and the middle part of the shell between two pulsed coils has inwardly protruded shell magnetic boots.
After adopting technique scheme, the utlity model has following advantage:
1, the direct driving force that drives the action of cranking arm comes from the energy that is stored in the spring, because the characteristic of spring is an energy maximum when just being released, so the utility model has satisfied the requirement of isolating switch just-off speed.Overcome the slow shortcoming of motor direct-drive isolating switch just-off speed.
2, again because energy-stored spring action back residue elastic force acts on the insulation rotating shaft all the time,, guarantee that contact is good so the back contact that closes a floodgate can keep enough pressure.
3, owing in gear box, increased transition gear, widened the distance between left gear and the right gear, two anglecs of rotation of cranking arm can expand to about 120 °, after turning over vertical point when cranking arm, last fulcrum begins to descend, and dwindles the effect of increasing basic neutralisation of formation with the scissors angle, so at moving contact during near fixed contact, moving contact becomes transverse movement by moving up and down, upwards impacting bus when having avoided the contact of two contacts; Isolating switch is obviously improved aspect mechanical stability.
4, behind the combined floodgate, crank arm under the effect of scissors gravity, two trend of cranking arm and clamping more help overcoming the loosening easily defective of common isolating switch combined floodgate back contact.
5, adopt spring energy-storage after, manual energy storage handle can be installed on drive unit, when motor breaks down can not energy storage the time, available manual energy storage, divide-shut brake speed is unaffected.
6, when the icing of isolating switch surface, can utilize the big characteristics of spring mechanism primary power, repeatable operation is impacted icing, thereby effectively implements the divide-shut brake action behind the icing, enlarges the suitable environment of this isolating switch.This is that the motor direct-drive device can't be accomplished.
