Detailed Product Description: | VDG-12 / vacuum circuit breakers for three-phase AC 50HZ, rated voltage 7.2KV ~ 12KV power system for switching in a variety of loads and frequent operation of the different nature of the occasion, and for industrial and mining enterprises, power plants and substation protection and control of electrical equipment used. Can be equipped with KYN28A-12 (GZSI) Used in the home, such as switchgear, can also be equipped with the XGN- □ fixed switchgear. VDG-12 / vacuum circuit breaker in line with the national standard edition GBI984 "AC high voltage circuit breaker", JB3855 "within 3.6 ~ 40.5KV indoor AC high voltage vacuum circuit breakers" and IEC60056 "high-voltage AC circuit breakers" standard. Meet DVr403 "within 10 ~ 35KV indoor high voltage vacuum circuit breaker ordering technology." VDG-12 / Vacuum Circuit Breaker Description: VS1-12 overall structure before and after vacuum circuit breaker operating mechanism and interrupter arranged in the form of vacuum interrupters installed in a vertical tubular insulation tube, insulation tube epoxy made of cast resin using APG process, so it is particularly anti-creepage. This design greatly reduces dust accumulation on the surface of the interrupter. Not only to prevent damage to the outside of the vacuum interrupter because the Department, but also to ensure that even in hot and humid and heavy pollution of the environment, but also on the effect of showing a high impedance voltage. 1.2 VDG-12 / vacuum circuit breaker in the closing position of the main circuit current path: the outlet seat 27 by fixing the bracket on the arc chamber 26 to the vacuum interrupter internal static contact, the moving contact and connection conductive clip, soft connection to the lower bracket 30 to the outlet seat 31. Each of the current level are equipped with an insulating tube when the circuit breaker factory dust cover, in actual use, the rated current and below grade 1250A runtime may not have removed, must be removed above the rated current level 1600A and runtime. 2 VDG-12 / vacuum circuit breaker operating mechanism actuator for layout of the spring mechanism, with manual storage and electric energy storage, actuator placed in front of the interrupter chassis, was among four bulkhead assembly space is divided into five, during which each actuator is equipped with energy storage, and transmission parts, tripping part and buffer section. VDG-12 / vacuum interrupter circuit breaker before the actuator arrangement consisting of a unified whole, which adopts the overall type arrangement, this structure is designed to allow the operating performance and interrupter operating mechanism to open and close the required performance is more anastomosis, reduce unnecessary intermediate transmission links, reducing energy consumption and noise, so VDG-12 / vacuum breaker operating performance more reliable. VS1-12 handcart loaded vacuum breaker switchgear can also be loaded into fixed switchgear. 2.1 Storage VDG-12 / vacuum circuit breaker switch by closing the energy needed to provide energy storage spring. Storage can be done by an external power drive motor can also be done manually using the charging handle. Storage Operation: by charging motor fixed on the framework, or the charging handle counterclockwise into the manual storage wells were shaking. When the electric energy storage led by motor output shaft sprocket drive system, manual storage by worm and worm wheel drive transmission. Sprocket rotates, the slider pin push on the wheel to follow the rotation axis so that the energy storage and energy storage by closing spring crank arm and stretching. Reaches the storage position, the limit on the frame slider bar pressure shaft and sprocket drive system makes storage disengaged, storage keep the catch against the wheel to keep the storage position, while the storage reservoir drive shaft connecting plate Flip can sign shows "charged" mark and switch the auxiliary power supply switch off electrical energy storage, then the circuit breaker in the closing state of readiness. 2.2 Closing VDG-12 / vacuum circuit breaker in the closing operation, regardless of the hand press the "closing" button or closing electromagnet so that the operation of the remote operation, can make the storage holding shaft is rotated, so that the catch release wheel, while the closing spring contraction crank arm by the cam shaft and the shaft rotating storage, which in turn drives the cam linkage mechanism insulated rod driven into the closed position and the moving contact and the contact compression spring to keep the contacts needed contact pressure. After closing the closing done in collaboration with the side to keep the catch to keep the closing position, while signs of energy storage, energy storage auxiliary electrical power supply circuit reset switch is turned on. If the external power supply is turned on again to enter the energy state, even the plates pull close / signs, showing that "together" mark, pulling the main transmission link auxiliary switch. Note: When the circuit breaker in the closing state or use without locking device to unlock the latch device and circuit breaker handcart in promoting the launch process, it can not perform the closing operation. 2.3 brake VDG-12 / vacuum breaker can press the "OFF" button, also connected to an external power source so reliable opening solenoid tripping or overcurrent tripping solenoid action to make the catch and keep closing axle solution buckle opening operation is achieved. By opening the contact springs and spring stored energy to make interrupter contact separation movement. In paragraph after opening process by opening the process of hydraulic shock absorbing surplus energy and limited open position. Pulled together by a connecting rod / min signs showing "minute" mark, while pulling counter, counter ,, achieve transmission link by pulling the main auxiliary switch. 3 anti-error interlock VDG-12 / vacuum breaker will provide comprehensive anti-misuse features. After 3.1 VDG-12 / vacuum circuit breaker closing operation is completed, the interlock switch on a downward bending bending two runs buckle closing, not opening when the circuit breaker will not switch on again. 3.2 After the closing circuit breakers, such as closing an electrical signal is not timely removal of internal anti-skip control circuit breaker will cut off closing the loop to prevent reclosing times. (Optional) 3.3 VDG-12 / vacuum breaker when not yet reached the test position or working position by bending three interlocking buckle closing bending pin 4 2, while closing off the circuit to prevent the circuit breaker in closing state into the load area. 3.4 VDG-12 / vacuum breaker after closing working position or test position, the roller 5 is pressed by advancing mechanism lock plate 6, will not be able to move the trolley to prevent the closing state advance or pull the load area. 3.5 If you use electrical closing lock in the locked position to prevent the closing unused operating unlocked case. Note: VDG-12 vacuum circuit breaker closing lockout power of 4.8W, operating voltage range of 0.65 to 1.1 times the rated voltage.
