The working cylinder and the energy storage cylinders are made into one body in the utility model, the sealing connection between the working cylinder and the energy storage cylinders is not needed, the oil leakage probability of the mechanism is reduced, moreover, comparing with the existing technology, the structure is more compact, the volume is considerably reduced, the processing and assembly are simple and the performance is more reliable.
Description
Technical field
The utility model relates to the high-voltage switch gear technical field of being with arc-control device, especially relates to the operation driving mechanism that uses hydraulic pressure in the electric switch.
Background technology
The present hydraulic actuating mechanism of existing primary cut-out, advantage such as it is fast that it has mechanism action speed, and power output is big; But exist complex structure, processing capacity is big, needs seal point many, easily causes the hidden danger of seepage oil, poor reliability; As China's utility model patent " hydraulic pressure spring operating mechanism ", notification number: CN2582142Y is that working cylinder and loaded cylinder are set up separately, by assembly unit plate and sealing ring with Bolt Connection together; Traditional hermetically-sealed construction is easy overheating failure when high-speed motion, influences useful life.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiency of above-mentioned prior art, to provide a kind of volume little, compact conformation, and process and assemble is simple and easy, dependable performance, good airproof performance, the hydraulic operating mechanism of high voltage circuit breaker that the draining probability is low.
For achieving the above object, the technical solution adopted in the utility model is such: a kind of hydraulic operating mechanism of high voltage circuit breaker, comprise fuel tank, main body plate, dished spring assembly, oil pump, motor, Hydraulic Elements and travel switch and auxiliary switch, it is characterized in that, said main body plate is made up of three uniform loaded cylinders around the working cylinder at center and the working cylinder, it is an overall structure, fixed oil cylinder on the main body plate, oil pump is fixedly connected outside the main body plate, motor and Hydraulic Elements, and have and establish oil duct in the main body plate and communicate with oil cylinder and oil pump, each energy storage oil cylinder and working cylinder all have oil duct to be connected simultaneously; Support seat on the main body plate periphery socket dish spring, the main body plate bottom dish spring guide cylinder that is spirally connected, the outer socket dish spring of dish spring guide cylinder is supported seat down; Dished spring assembly places the dish spring to support between seat up and down; In said working cylinder differential piston is arranged, its piston rod and auxiliary switch join; Piston is arranged in the loaded cylinder, support seat to link on its piston rod and the dish spring.
The course of work of the present utility model is as follows:
When energy storage, connect the Oil pump electrical machinery loop, oil pump output hydraulic oil enters loaded cylinder simultaneously, the energy storage piston is moved down the compression disk spring energy storage; Travel switch cut off motor power after energy storage put in place, the oil pump stall, and energy storage finishes.
During combined floodgate, switch is in the separating brake position, receives reclosing command, control valve switches to "on" position, and differential piston base and hydraulic oil are connected in the working cylinder, and differential piston upwards closes a floodgate fast, and drive the auxiliary switch switching, disconnect closing circuit, for separating brake is got ready.
During separating brake, switch is in closing position, receive the separating brake instruction, control valve switches to gate-dividing state, and differential piston bottom hydraulic oil is communicated to oil sump tank by reversal valve, in the differential piston upper end under the high pressure effect, the fast downward separating brake of differential piston, and drive the auxiliary switch switching, and disconnect sub-gate circuit, get ready for closing a floodgate next time.
Owing to adopted technique scheme, a kind of hydraulic operating mechanism of high voltage circuit breaker of the present utility model, working cylinder and loaded cylinder are made of one, do not need between loaded cylinder and working cylinder, to carry out sealed attachment, reduced the leakage of oil probability of mechanism, and than prior art, structure is more compact, volume dwindles greatly, and process and assemble is simple and easy, and performance is more reliable.
