Abstract
The utility model relates to a slow-disconnecting and slow-connecting apparatus for circuit breaker, comprising a pulling lever, a transmission nut, a bending arm, a lead screw, a channel steel, a rotary shaft, a pressure bearing and a handle. The transmission nut is fixed at the upper part of the bending arm; the middle shaft of the bending arm is connected with the pulling lever; one end of the lead screw meshes with the transmission nut, the other end of the lead screw passes through the breaker beam, the channel steel, and the transmission shaft, and then is arranged on the rotary shaft and is fixed to the handle; the channel steel and the support are connected with the breaker beam. The rotary handle can be used to rotate the lead screw, and then the mesh of the lead screw and the transmission nut rotates the bending arm for an arc rotation, so the aim that the pulling lever is moved in a slower speed, and the breaker can be connected or disconnected slowly, and the utility model is convenient for operation personnel to install, adjust, maintain at any position is attained. The utility model is characterized in simple structure, reliable connection, flexible operation, convenient assembly, so the utility model is suitable for any breaker using horizontal pulling lever as transmission mechanism.
Description
Technical field
The utility model relates to a kind of circuit breaker, refers in particular to a kind of slow-disconnecting and slow-connecting apparatus of circuit breaker.
Background technology
Outdoor high voltage circuit breaker and various circuit breaker by the girt transmission, in its installation, debugging and maintenance process, all wish branch, close mechanism and can arbitrarily rest on needed optional position, so that install, overhaul and observe this motion of mechanism process, search the reason that goes wrong.In existing circuit breaker, by with spring, hydraulic pressure, pneumaticly realize this operation for power moves pull bar, because course of action is uncontrollable, can not be with the branch in the circuit breaker, close mechanism and divide slowly, close slowly or accurate location, for installation, debugging and maintenance have brought many inconvenience.
Summary of the invention
The purpose of this utility model provides a kind of slow-disconnecting and slow-connecting apparatus that the mechanism in the circuit breaker arbitrarily can be rested on the optional position, so that install, debug and the maintenance circuit breaker.
Technical solution adopted in the utility model is: a kind of slow-disconnecting and slow-connecting apparatus of circuit breaker, comprise pull bar 1 and circuit breaker crossbeam 2, and also comprise transmission nut 3, connecting lever 4, leading screw 5, channel-section steel 6, rotation axis 7, pressure bearing 8, handle 9 and support 10.Transmission nut 3 is fixed on the upper end of connecting lever 4, and the jack shaft of connecting lever 4 is connected on the pull bar 1.One end of leading screw 5 and transmission nut 3 engagements, the other end are passed circuit breaker crossbeam 2, channel-section steel 6 and rotation axis 7 back being seated on the rotation axis 7 and with handle 9 by pressure bearing 8 and are fixed, and channel-section steel 6 and support 10 are screwed onto on the circuit breaker crossbeam 2.By driving the rotation of connecting lever 4, and then drive moving of pull bar 1, reach with minute, close the purpose that mechanism rests on the optional position.
The beneficial effects of the utility model are: owing to can drive the leading screw rotation by turning handle, do the arc rotation by the engagement drive connecting lever of leading screw and transmission nut again, and then drive pull bar with slower speed and move, reach the branch that makes in the circuit breaker, close mechanism and divide slowly, close slowly, and can rest on that any position handled easily personnel install, the purpose of debugging and maintenance.Again since the utlity model has simple in structure, connect reliable, flexible operation and be convenient to assembling, therefore be applicable to that any is the circuit breaker of transmission mechanism with the girt.

Fig. 2 is the utility model left view.
Fig. 3 is installed in structural representation on the circuit breaker for the utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is done to describe in further detail.
As shown in Figure 1 and Figure 2, a kind of slow-disconnecting and slow-connecting apparatus of circuit breaker comprises pull bar 1 and circuit breaker crossbeam 2, also comprises transmission nut 3, connecting lever 4, leading screw 5, channel-section steel 6, rotation axis 7, pressure bearing 8, handle 9 and support 10.Transmission nut 3 is fixed on the upper end of connecting lever 4, and the jack shaft of connecting lever 4 is connected on the pull bar 1.One end of leading screw 5 and transmission nut 3 engagements, the other end are passed circuit breaker crossbeam 2, channel-section steel 6 and rotation axis 7 back being seated on the rotation axis 7 and with handle 9 by pressure bearing 8 and are fixed, and channel-section steel 6 and support 10 are screwed onto on the circuit breaker crossbeam 2.Rotate by driving connecting lever 4, and then drive pull bar 1 moves, reach with minute, close the purpose that mechanism rests on the optional position, on the other hand, leading screw 5 itself is the axle center with rotation axis 7 also, along with the circular arc of connecting lever 4 rotates and swings up and down, reach the branch in the circuit breaker, close the purpose that mechanism divides slowly, closes slowly.
As shown in Figure 3, the utility model slow-disconnecting and slow-connecting apparatus is installed on the circuit breaker, turning handle 9, can make connecting lever 4 reach 34.04 ° left, 33.27 ° the anglec of rotation to the right, and then by the five connecting rod adjusting mechanisms running in the pull bar 1 drive circuit breaker, and can make this mechanism rest on the optional position, so that operating personnel's installation, debugging and maintenance.
