Problems solved by technology

[0002] In the operating mechanism of high-voltage circuit breakers, the commonly used energy storage devices of traditional hydraulic disc springs are generally composed of a group of disc springs connected to multiple accumulator cylinders, which have the following problems in use: 1) due to processing errors, etc. Difficulties in assembly and installation caused by avoidable reasons; 2) Since the processing error cannot be automatically compensated, the accumulator, etc. are easy to strain the cylinder body during pressurized operation; 3) The accumulator has many sealing points and is easy to leak; 4) The installation of the disc spring is more complicated and needs to be installed together with the working cylinder

Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] Such as figure 1 , figure 2 As shown, a hydraulic disc spring energy storage device for a high-voltage circuit breaker includes a piston 1 in a hydraulic cylinder 11, a force transmission flange 2 and a disc spring mechanism. The disc spring mechanism includes a disc spring supporting flange 4. The disc spring One side of the spring support flange 4 can be radially connected with a transition flange 3, and is fixedly connected with the hydraulic cylinder block 11 through the transition flange 3; the other side of the disc spring support flange 4 is axially extended with a disc spring Sleeve, the large support ring 5, a group of disc springs 6, the small support ring 9 and the snap ring 10 are arranged successively on the disc spring sleeve. The pipe 8 is composed of pipes, which can be connected with each other by matching t...

Abstract

In order to overcome the structural defects of the hydraulic disc spring multi-accumulator of the traditional high-voltage circuit breaker operating mechanism, the present invention discloses a single-cylinder hydraulic disc spring energy storage device, which includes a piston in a hydraulic cylinder, a force transmission flange and a disc The disc spring is arranged in a separate disc spring mechanism, which is fixedly connected to the hydraulic cylinder body through a transition flange, and connected to one end of the piston through a central ball bearing on the piston side of the force transmission flange. In the radial direction on the other side of the force transmission flange, three dowel rods are uniformly distributed along its circumferential surface. One end of the dowel rod is connected to the force transmission flange through a circumferential ball bearing, and the other end is connected to the disc spring mechanism. The hydraulic disk spring energy storage device of the present invention has convenient installation of the disk spring, can automatically compensate processing errors within a certain range during use, has few leakage points, and will not strain the cylinder body during pressurized operation.
