Embodiment Construction

[0014] Below in conjunction with accompanying drawing, this patent is described in further detail.

[0015] Spring operating mechanism of the present invention (as figure 1 , figure 2 , image 3 , 4 Shown), is a splint structure. Place the left wall plate 51 and the right wall plate 1 in parallel as the main support fixed body, and fix the two small support plates 52, the opening spring support plate 61 and the closing spring support plate 53 on the left wall plate 51 with bolts. Place the four corners of the wall plate between the right wall plate 1 and the right wall plate.

[0016] (Such as image 3 , 4 As shown) the opening spring guide sleeve 63 and the closing spring guide sleeve 64 are respectively fixed on the opening spring support plate 61 and the closing spring support plate 53, and placed between the two wall plates; the closing spring 15 is worn on the On the closing spring guide sleeve 64, it is placed between the closing spring seat 12 and the closing sp...

Abstract

The invention discloses a high power spring operating mechanism, and belongs to the technical field of power transmission and transformation. The mechanism comprises a left wall board, a right wall board, a switch-off spring cylinder, a switch-on spring cylinder, a master switch-off pawl, an auxiliary switch-off pawl, a switch-on pawl, a motor, a multi-stage transmission gear, an energy storage pawl, a check pawl, an energy storage shaft system, a transmission chain system and so on. According to the spring operating mechanism provided by the invention, the switch-off spring cylinder and the switch-on spring cylinder are arranged between the two wall boards which are arranged in parallel; two shaft rotation systems of the energy storage shaft system and a transmission shaft system are arranged on the two wall boards; a switch-off pawl system is arranged on the left wall board; and a switch-on pawl system and the energy storage system are arranged on the right wall board. The spring operating mechanism provided by the invention has the advantages of high switch-on and switch-off power, rapid speed, stable mechanical property, high reliability, small size and straight output.

Description

technical field [0001] The invention relates to a super-high-power spring operating mechanism for a high-voltage circuit breaker, belonging to the technical field of high-voltage power transmission and transformation. technical background [0002] The spring operating mechanism is an important equipment in the field of high-voltage power transmission and transformation, and is an important part of the high-voltage circuit breaker. The closing and opening operations of the high-voltage circuit breaker are realized through the operating mechanism. The operating mechanisms of high-voltage circuit breakers are mainly divided into two types: hydraulic and spring. It has disadvantages such as difficulty in realization; the spring operating mechanism has the characteristics of low cost, simple structure, intuitive principle, and less maintenance, and is suitable for extensive and large-scale use on high-voltage circuit breakers. [0003] Currently, spring operating mechanisms used...
