Problems solved by technology

[0003] In the application of the above-mentioned opening spring structure, there are the following problems: 1. Special tools are required for installation, which is time-consuming, laborious and inconvenient
2. Since the opening spring is in a fixed state after one installation, its reset force cannot be adjusted. Therefore, the opening spring has a great influence on parameters such as closing and opening speeds, and the parameters cannot be adjusted to achieve ideal values, which will affect the entire system. The working performance of the circuit breaker

Embodiment Construction

[0011] see figure 1 . This figure only shows the adjustable opening spring structure installed on one side of the circuit breaker box wall 8, in fact, two sets of adjustable opening spring structures are symmetrically installed on both sides of the box body. The crank arm at the middle part of the rotating shaft 7 is connected with the mechanism of the circuit breaker, and the external splines at both ends of the rotating shaft 7 are engaged with the internal splines in the mounting holes of the transmission crank arms 6 on both sides respectively. One end of the transmission crank arm 6 is hinged with the cylinder upper end of the guide plate 3 through the pin shaft 5 . The cylinder is divided into three parts whose diameters increase sequentially from top to bottom, and the surface of the cylinder in the middle part of the cylinder is provided with external threads, which match the internal threads of the inner hole of the spring seat 4, that is, the guide plate 3 and the s...

Abstract

A breaker adjustable tripping spring structure comprises a mounting plate, a guide plate, a tripping spring provided on the body of the guide plate and a spring seat thereof; the mounting plate is fixedly mounted on the box wall of the breaker; the mounting plate is provided with a guide through hole with the coincide shape with that of the cross section of the guide plate; upper part of the vertically mounted guide plate is hinged with a transmission shaft through the pin shaft, and the lower part penetrates the guide through hole; body of the guide plate is sleeved with the spring seat; thetripping spring is sleeved on the body of the guide plate between the lower plane of the spring seat and the upper plane of the mounting plate; the structure is characterized in that: the guide plateis a cylinder; the cylinder surface on the upper part of the cylinder is provided with external thread; the internal ho9le of the spring seat is provided with internal thread; the cylinder and the spring seat are coupled into one through the internal and external threads. The invention has the advantages without using special tool mounting, and capable of conveniently adjusting the spring reset force after assembling.

Description

【Technical field】 [0001] The invention relates to a ZN85-40.5 indoor vacuum circuit breaker, in particular to the opening spring structure of the circuit breaker. 【Background technique】 [0002] The existing opening spring structure on the ZN85-40.5 indoor vacuum circuit breaker includes a mounting plate, a guide plate, opening spring and its spring seat arranged on the guide plate. The mounting plate is fixedly installed on the wall of the circuit breaker box body, and a guide through hole whose shape is consistent with the cross section of the guide plate is opened on it. The guide plate is a vertically installed plate body with a rectangular cross-section. The upper part is hinged with a transmission crank arm through the pin shaft, and the lower part stretches through the guide through hole. The spring seat is sleeved on the body of the guide plate. Positioned by the radial positioning block on the plate body, the opening spring is sleeved on the guide plate body betwee...
