Description
Technical field
The utility model is related to breaker technical fields, are exactly specifically the energy storage conjunction for being related to a kind of circuit breaker operation mechanism
Lock interlocking mechanism.
Background technology
Breaker is divided into high-voltage circuitbreaker and low-voltage circuit breaker by its use scope.Low-voltage circuit breaker is also known as automatic switch,
It is commonly called as " air switch " and also refers to low-voltage circuit breaker, it is a kind of existing manual switch effect, and can carry out decompression automatically, owe
The electric appliance of pressure, overload and short-circuit protection.It can be used to distribute electric energy, infrequently start asynchronous motor, to power circuit and
The implementations such as motor protect, when they occur it is serious overload or short circuit and it is under-voltage when failures when can automatic shutdown circuit,
Function is equivalent to Fuse switch and crosses the combination of underheat relay etc., and need not generally become after disjunction fault current
More parts have had been widely used.
The switching electromagnet of breaker closing execution structure is fixed on above operating mechanism currently on the market, and operating mechanism closes
There is a cantilever on brake lever rod, switching electromagnet iron core is located at the top of operating mechanism closing lever cantilever；It needs to carry out operation machine
When structure closes a floodgate, switching electromagnet iron core is got, the closing lever of actuating procedure mechanism, and then is promoted in operating mechanism floodgate semiaxis
Cantilever rotated semiaxis so that mechanism carry out closing operation.The closing lever mechanism of breaker of the prior art
Be by separating brake semiaxis notch, side plate notch and mechanism cover board and closing lever end come the power of limit levels torsional direction, but
