Abstract
The utility model relates to a three service position operation device for air insulated metal closed switch device, which is characterized in that a dial group is arranged on the output shaft coupling, at least two nuts are arranged on the transmission device, the transmission devices are symmetrically arranged on two sides of the dial group. Gear drives screw to rotate during application, nut engaged with screw is driven to make linear movement, then nut drives dial disc connecting to output shaft to rotate around axle of output shaft, then drives output shaft to rotate clockwise or anti-clockwise. Output angle of output shaft is completely decided by shape of the dial disc, which solves the problem that output angle of the operation device is difficult to control stably and accurately in long term. When grounding switch is on tripping position, isolation switch is only on gate position because of blocking, nut don't move to tripping direction; When the isolation switch is on gate position in same principle, the grounding switch is only on the gate position, so mechanical interlocking of two switches is solved.
Description
Technical field:
The technical field that the utility model relates to specifically is used for three station manipulation devices of Cubicle Gas-Insulated Switchgear.
Background technology:
Present normally used electrically operated device mostly is the principle that the turbine and worm drive mechanism adds mechanical clutch, and the control of output angle is by being installed on sensitive switch and the mechanical clutch acting in conjunction on the turbine motion circular path.The motor-operating mechanism of this theory structure requires very high to the installation site and the temperature variant characteristic of sensitive switch of sensitive switch, simultaneously, because there is mechanical wear in mechanical clutch, therefore, the output angle of this mechanism is difficult to guarantee long-term accurate control.
Earthed switch and isolating switch in the 110KV Cubicle Gas-Insulated Switchgear of existing box structure altogether are knockdown, need the mechanism promptly can the actuating earthed switch, also can the actuating isolating switch, and, also must satisfy mechanical interlocked requirement each other in-house.Traditional powder operation device can only be respectively the configuration of earthed switch or isolating switch, that is to say that mechanism of a switch configuration can not realize between mutually mechanical interlocked.
Summary of the invention:
The purpose of this utility model is to provide a kind of improved three station manipulation devices that are used for Cubicle Gas-Insulated Switchgear, the output angle that it can overcome mechanism in the prior art be difficult to guarantee long-term accurate control and mechanism of a switch configuration, can not realize mechanical interlocked some shortcomings between mutually.
To achieve these goals, the technical solution of the utility model is: the three station manipulation devices that are used for Cubicle Gas-Insulated Switchgear, it mainly comprises output shaft, transmission device and sensitive switch, it is characterized in that: the sheathed dial group of output shaft, transmission device is provided with at least two nuts, and transmission device is symmetricly set on dial group both sides.
During use, motor rotatablely moves by the gear driven leading screw, is done rectilinear motion with the nut of leading screw engagement by drive, and the dial that nut promotes to be connected with output shaft again is around the output shaft rotational, thereby the drive output shaft is made positive and negative clockwise and rotatablely moved.The output angle of output shaft does not need the accurate location of sensitive switch fully by the shape decision of dial, has thoroughly solved the operating means output angle and has been difficult to problem long-term, stable, accurate control.When earthed switch is in closing position and since dial stop that isolating switch can only be in the separating brake position, nut can not move to the combined floodgate direction; Same principle, when isolating switch is in closing position since dial stop that earthed switch can only be in the separating brake position, nut can not move to closing position, this has just solved the mechanical interlocked of two kinds of switches.

Fig. 4 is another user mode reference diagram of the present utility model
Embodiment:
The utility model will be further described below in conjunction with drawings and Examples.
The utility model mainly comprises output shaft 1, transmission device and sensitive switch 2, and its difference with the prior art is: the sheathed dial group 3 of output shaft, and transmission device is provided with at least two nuts 4, and transmission device is symmetricly set on dial group both sides.Transmission device is made of with the leading screw 6 that links to each other with gear two gears 5, and the dial group is made of upper and lower disc, and upper and lower disc is separately positioned on the upper and lower side of transmission device, and each leading screw is provided with a nut that is meshed with leading screw.Output shaft links to each other with isolating switch with earthed switch by a connecting axle, and an end of dial is circular-arc, and the other end of dial is respectively equipped with two planes of matching with nut.Nut overcoat is provided with a square positioning box, and the corresponding side of positioning box and sensitive switch is provided with left and right two chamferings.
In force, motor rotatablely moves by the gear driven leading screw, is done rectilinear motion with the nut of leading screw engagement by drive, and the dial that nut promotes to be connected with output shaft again is around the output shaft rotational, thereby the drive output shaft is made positive and negative clockwise and rotatablely moved.The nut (referring to Fig. 2) of symmetric arrangement on two rhizoid thick sticks is controlled earthed switch and isolating switch by the rotation of dial respectively.After nut moves to lower end position, trigger the power supply that sensitive switch cuts off power set (motor), leading screw stops operating.There is one section flat face at the position that dial contacts with nut, needs only nut in this section flat face scope, and the position of dial is fixed.Therefore, because the sensitive switch characteristic varies with temperature, perhaps the sensitive switch error in mounting position needs only nut and stops in this section flat face, and the final position of dial can not change.This shows that the output angle of output shaft does not need the accurate location of sensitive switch fully by the shape decision of dial, thoroughly solved the operating means output angle and be difficult to problem long-term, stable, accurate control.
As shown in Figure 3, when earthed switch is in closing position since dial stop that isolating switch can only be in the separating brake position, nut can not move to the combined floodgate direction; Same principle, as shown in Figure 4, when isolating switch is in closing position and since dial stop that earthed switch can only be in the separating brake position, nut can not move to closing position, this has just solved the mechanical interlocked of two kinds of switches.
