Embodiment Construction

[0017] specific implementation

[0018] A spring operating mechanism see figure 2 , image 3 As shown, it mainly includes the transmission actuator formed by the clamping of the left wall plate 2 and the right wall plate 24 arranged in parallel; able agency. The transmission executive mechanism and the energy storage mechanism are arranged in parallel, and are fixedly connected by a spring cylinder flange 50 therebetween. Energy is transmitted between the two through the connecting plate 42 .

[0019] The transmission actuator described in image 3 , Figure 4 As shown, it is clamped by the left wall plate 2 and the right wall plate 24 arranged in parallel, and the right side in the middle of the two wall plates is fixed with two positioning columns 1 to limit the position, and the left side is limited by the spring tube flange 50 with the fixing bolt 16 fixed.

[0020] Camshaft 54 ​​wears on two wall plates and places the center of the wall plates. Such as image 3 ...

Abstract

The invention discloses a spring operating mechanism for a circuit breaker, which mainly comprises a transmission execution mechanism and an energy storage mechanism, wherein a left wall plate and a right wall plate arranged parallelly are clamped to form the transmission execution mechanism; the energy storage mechanism is formed by a buffer, an opening spring, a spring sleeve and a closing spring from inside to outside in a sleeving mode; the transmission execution mechanism and the energy storage mechanism are arranged parallelly and a spring sleeve flange is used for fixed connection in the middle; and energy between the two is transmitted by a connection plate. An adjusting pull rod is used for connecting a left energy storage crank arm, a right energy storage crank arm and a support plate respectively, the outer output shaft of the left wall plate is provided with a closing pawl and a closing pawl reset spring, and the outer crank shaft of the right wall plate is driven by a motor. The technical problems that the existing spring operating mechanism is large in size, complicated in structure, small in output power, difficult in making process, instable in opening and closing time and the like can be solved.

Description

technical field [0001] The invention belongs to the technical field of high-voltage power transmission and transformation. It relates to a super-power spring operating mechanism for a high-voltage circuit breaker. technical background [0002] The circuit breaker is an important equipment in the field of high-voltage power transmission and transformation. The spring operating mechanism 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 spring operating mechanism. The operating mechanisms of high-voltage circuit breakers are mainly divided into hydraulic and spring operating mechanisms. The hydraulic operating mechanism has the advantages of short opening and closing time and stability, but has the disadvantages of complex structure, high cost, and difficult technical realization; The spring operating mechanism has the characteristics of low cost, simple structure, and long...
