Embodiment Construction

[0017] Depend on figure 1 It can be seen from the figure that the hanging spring shaft (15) penetrates into the middle hole at the lower end of the left and right side splints (1, 2) and is fixed and tightened by a nut, and the gear on the gear shaft (14) is symmetrical to the No. 1 gear (11) Bite each other to form a first-stage gear transmission. Shaft B (12) penetrates into the middle of No. 2 gear (13) and No. 1 gear (11). Both ends of shaft B (12) are fixed on the splints (1, 2) on the left and right sides, shaft A (9) penetrates between No. 3 gear (10) and No. 4 gear (8), No. 3 gear (10) and The No. gear (13) is symmetrically engaged and fixed on the lower end of the closing detent shaft (7), and at the same time, the two ends of the shaft A (9) and the closing detent shaft (7) are fixed on the left and right splints (1, 2) , forming a two-stage gear transmission, the energy storage shaft (5) penetrates into the middle of No. 5 gear (4) and is fixed at the lower end o...

Abstract

The invention provides a spring operation mechanism used for a high voltage electric appliance. The mechanism mainly comprises a left side clamping plate, a right side clamping plate, a switch-on haft shaft, a number 5 gear, an energy storage shaft, a closing latch, a closing latch shaft, a number 4 gear, a shaft A, a number 3 gear, a number 1 gear, a shaft B, a number 2 gear, a gear shaft, and a hanging spring shaft. The mechanism is characterized in that: the left side and right side clamping plates form a vertical type mechanism symmetrically, a distance between the clamping plates is 108mm to 130mm, and the vertical type mechanism is composed of three levels of gear transmission. The mechanism has the following advantages that: quantity of parts is few and is about 150, material is saved by about 53%, volume is small, cost is low, a structure is simplified and compact, switch-on work of the mechanism is raised by three times, power consumption is small, characteristics of the mechanism is stable, reliability of long-term operation is high, a service life is long, maintenance is small, and the mechanism can be completely matched with a 35KW vacuum circuit breaker or a small oil circuit breaker and a sulfur hexafluoride breaker.

Description

technical field [0001] The invention relates to a spring operating mechanism, in particular to a spring operating mechanism for high-voltage electrical appliances. Background technique [0002] The current circuit breaker switches used by high-voltage electrical appliances in my country have been widely used due to their own advantages. The CT19 spring operating mechanism is specially designed for vacuum circuit breakers. See image 3 , which is the overall structural diagram of the existing CT19 spring operating mechanism. It is matched with ZN28-10 vacuum circuit breaker and ZN28A suspension vacuum circuit breaker and can be used for protection and control of electrical facilities in industrial and mining enterprises, power plants and substations. . [0003] Yet existing supporting CT19 type spring operating mechanism still exists a lot of defects. For example, the number of parts is about 280, the volume is large, the materials are consumable, the fastening is poor, the ...
