Description
Technical field
This utility model relates to high voltage power distribution technical field, particularly relates to a kind of Novel side-mounted spring vacuum circuit breaker.
Background technology
Vacuum circuit breaker, initially by English, U.S. research, is subsequently progressed to the other countries such as Japan, German and former Soviet Union.China is theoretical from the nineteen fifty-nine vacuum circuit breaker that begins one's study, and formally produces all kinds of vacuum circuit breaker to early 1970s.Along with the manufacturing technologies such as vacuum interrupter, operating mechanism, dielectric level are constantly brought forth new ideas and improve, the development making vacuum circuit breaker is extremely rapid, achieves a series of great achievement in terms of Large Copacity, miniaturization, intellectuality and reliability consideration.Net that transformation, chemical industry, metallurgy, railway be electric and the industry such as mine is widely used in current China's electric power town and country state.But due to relatively costly, the permanent magnet demagnetization of permanent magnet mechanism, therefore its economic and practical scope is restricted；And the spring mechanism of other forms is bigger because of its overall volume, it is impossible to meet the requirement of miniaturization switchgear.The most complete high-pressure vacuum breaker deficiency in reality is applied a, it has also become technical problem to be solved.
Utility model content
The purpose of this utility model is to provide a kind of Novel side-mounted spring vacuum circuit breaker, this spring vacuum circuit breaker is while keeping existing vacuum circuit breaker technical advantage and improving prior art parameter, use the problem that spring mechanism does not exist permanent magnet demagnetization, low cost, volume are little, are suitable for the most extensive.
To achieve these goals, this utility model have employed following technical scheme: a kind of Novel side-mounted spring vacuum circuit breaker, including a housing, housing includes mechanism chamber and communicates with mechanism chamber and vertically disposed under casing, is provided with spring mechanism, power module, drive mechanism, energy storage motor, manual brake separating, closing by hand in described mechanism chamber；
Described spring mechanism is arranged on middle part in mechanism chamber, and spring mechanism connects a connecting lever；
Being provided with energy storage energy storage motor on the top of described spring mechanism, bottom is provided with drive mechanism；
Described drive mechanism includes first connecting rod, guides bent plate, second connecting rod；
Described under casing upper end is vertically arranged with multiple vacuum interrupter, and described vacuum interrupter uses pole, is respectively connected with pull bar below each vacuum interrupter, and pull bar is connected with second connecting rod.
Wherein, being equiped with divide-shut brake coil inside described spring mechanism, divide-shut brake coil is located at the power supply output of power module.
Wherein, being additionally provided with the state indicating device into the instruction of circuit-breaker switching on-off state in described mechanism chamber, state indicating device is connected with first connecting rod.
Wherein, in the middle part of described spring mechanism, it is equiped with auxiliary switch.
The beneficial effects of the utility model are: spring vacuum circuit breaker uses spring mechanism, not only reduce product cost, Reliability of Microprocessor height；It is to keep circuit breaker position by machinery separating brake semiaxis because of it again, so not depositing with worrying the problem such as permanent magnet demagnetization.Spring vacuum circuit breaker uses pole type vacuum pipe simultaneously, effectively raises the insulating capacity of chopper.
Mechanism is simple, rationally distributed.Vacuum interrupter is longitudinally mounted becomes word order with mechanism chamber, volume is greatly reduced, inside vacuum tube sealing and pole, even if under rugged environment, remaining to keep the highest creepage performance and insulating properties, without blast, pollution-free, noise is low, volume is little, lightweight, the life-span is long.
