The electric operation mechanism consists of modular functional units and has simple structure, small volume, light weight, convenient installation and commissioning and can operate the three-working-position switch of a fully-closed combined electric appliance.
Description
Technical field
The utility model belongs to High-Voltage Electrical Appliances, is specifically related to a kind of motor-operating mechanism that is used for the three-station of fully closed combined electric unit.
Background technology
Existing be used for the isolation of fully closed combined electric unit, the operating mechanism of earthed switch mostly is the motor drive mechanism of two stations, it finishes branch, closing operation by motor-driven screw mandrel and the transmission of feed screw nut's connecting rod, there is the defective that is not easy upper boom behind feed screw nut's lower beam, can not operates three-station isolating/grounding switch simultaneously.Also there are defectives such as volume is big, operating physical force is big, amount of parts is many in this mechanism.
The utility model content
The purpose of this utility model is at above defective, proposes a kind of motor-operating mechanism that is used for High-Voltage Electrical Appliances, and this operating mechanism can be operated the three-station of fully closed combined electric unit.
Realize that the above-mentioned purpose technical scheme is:
The utility model motor-operating mechanism comprise the motor that is equipped with in casing, the casing, the worm gear that links to each other with motor, worm gear box, with coaxial gear mechanism, cam, the connecting plate of worm gear, gear mechanism and load are joined; Cam matches with the limit switch of motor, connecting plate and auxiliary switch interlock.
Described motor-operating mechanism also has hand gear, and hand gear comprises the handle engages axle, and the handle engages axle is connected with worm screw in worm gear, the worm gear box by sprocket wheel, link chain mechanism.

Embodiment
As shown in Figure 1 and Figure 2, this motor-operating mechanism is a kind of operating mechanism that is used for three-station on the fully closed combined electric unit.It comprises casing 20, and the main body running part that is equipped with in the casing 20 comprises chain 1, motor 2, worm screw 3, worm gear 4, gear 5, bevel gear 6, bevel gear 7.The deceleration of the transmission of the rotation of motor 2 by chain 1, worm gear 4 worm screws 3, drive load movements through gear 5, bevel gear 6, bevel gear 7 at last.Motor 2 is fixed on by rebound 11 on the mounting panel 12 of mechanism, and the output shaft on the motor 2 connects together with the sprocket wheel 9 that is enclosed within on the worm screw 3 by sprocket wheel 10, chain 1.Worm gear 4, gear 5, cam 13 connect together by main shaft 8, when electric operating is about to combined floodgate or separating brake position, cam 13 on the main shaft 8 promotes corresponding limit switch and switches, and makes motor 2 outages, and connecting plate 18 drive auxiliary switches 19 rotations of being fixed on the main shaft 8 are switched.On handle engages axle 15, insert handle, by being contained in the rotation of handle engages axle 15 upper sprocket wheels 14, drive worm screws 3 and rotate, thereby can realize manual branch, closing operation through chain 16, sprocket wheel 17.
Operation principle of the present utility model: motor-operating mechanism is in gate-dividing state, when the tri-station isolating switch switching signal triggers, motor 2 energisings are rotated counterclockwise, slow down through gear 5 and worm screw 3 worm gears 4, drive main shaft 8 and axle and go up each parts clockwise direction rotation, drive tri-station isolating switchs by bevel gear 7 and close a floodgate.When the tri-station isolating switch sub-gate signal triggered, motor 2 backward rotation realized separating brake.
Motor-operating mechanism is in gate-dividing state, when three station earthed switch switching signals triggered, motor 2 energisings turned clockwise, and slowed down through gear 5 and worm screw 3 worm gears 4, drive main shaft 8 and axle are gone up each parts and are counterclockwise rotated, and drive three station earthed switches by bevel gear 7 and close a floodgate.When three station earthed switch sub-gate signals triggered, motor 2 backward rotation realized separating brake.
The rotating of motor 2 utilizes two contactors to control and interlocking, the adhesive action of can not switching on simultaneously of two contactors.When electric operating was about to combined floodgate or separating brake position, the cam 13 on the main shaft 8 promoted corresponding limit switch and switches, and made motor 2 outages; The connecting plate 18 that is fixed on the main shaft 8 drives auxiliary switch 19 rotation switchings.Axle 15, sprocket wheel 14, chain 16, sprocket wheel 17, worm screw 3 systems are used for inserting where necessary that handle manually divides, closing operation.Electromagnetic lock is used for realizing manually and electronic interlocking, that is: can not be electronic manually the time, and can not be manual when electronic.
Claims (2)
1, a kind of motor-operating mechanism that is used for High-Voltage Electrical Appliances, comprise casing, it is characterized in that also comprising the motor that is equipped with in the casing, the worm gear that links to each other with motor, worm gear box, with coaxial gear mechanism, cam, the connecting plate of worm gear, gear mechanism and load are joined; Cam matches with the limit switch of motor, connecting plate and auxiliary switch interlock.
2, according to the described motor-operating mechanism that is used for High-Voltage Electrical Appliances of claim 1, it is characterized in that being provided with hand gear, hand gear comprises the handle engages axle, and the handle engages axle is connected with worm screw in worm gear, the worm gear box by sprocket wheel, link chain mechanism.
