Description
Technical field
The invention belongs to low voltage equipment technical field, is exactly specifically to be related to a kind of breaker to be filled with manual energy storage
Put.
Background technology
Breaker is divided into primary cut-out and low-voltage circuit breaker by its use range.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 hand switch effect, and and can carries out decompression, owed automatically
The electrical equipment 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 are protected, when serious overloads or short circuit and the failure such as under-voltage occurs in they can automatic shutdown circuit, its
Function equivalent to Fuse switch and the combination for crossing underheat relay etc., and it is latter in disjunction fault current as need not become
More parts, obtain a wide range of applications.
As shown in Figure 1, frame-type circuit breaker is designed with manual energy storing device at present, and traditional manual energy storing device is hand
Energy storage is pulled before and after handle, it is necessary to which an individually designed energy accumulation handle, energy accumulation handle are directly mounted on operating mechanism energy storage main shaft
Carry out pulling energy storage；Or be installed on mechanism side plate, by the lever of some row, band pneumatic operating mechanism energy storage main shaft is pulled
Dynamic energy storage；This traditional energy storage mode needs to pull handle energy storage with hand, once switch is too high in the upper-lower position of power distribution cabinet
Or it is too low can all cause to pull handle it is not very convenient；Secondly, it is front and rear pull force ratio that handle energy storage mode needs compared with
Greatly, user's hand can be caused uncomfortable after multiple energy storage；3rd, because the length of handle is limited by construction of switch, handle length
Degree can not possibly increase without limitation, and it is difficult to be reduced to the stage of people's force feeling as snug as a bug in a rug to cause handle energy storage power；In addition in switch
A handle is clearly can be appreciated that on mask, destroys the overall integrity of mask outward appearance.
Traditional rotation input mode is worm gear, worm-drive or Bevel Gear Transmission on the other hand, these transmission sides
It is accurate that formula requires that accessory size makes, and matching requirements are higher, causes manufacture, assembly difficulty increase.Meanwhile worm and gear and
The direction of transfer of bevel gear is fixed, input torque clockwise or counter-clockwise, the direction meeting of the output torque finally given
Changed with the direction of input；If there is opposing torque is manually entered, whole mechanism just cannot get predetermined energy storage effect, even
Stored energy mechanism is damaged.
