Abstract

A manual and electric dual-purpose operating mechanism for universal three-station isolation switch used for closing, separating and grounding operation driving for indoor or inside cabinet separation loading switches. It includes an electric motor and a gearing mechanisms, an execution mechanisms and a peripheral electric control parts. A flute profile board is installed on its main output shaft. Four flute profile gaps are located evenly on the semi revolution surface of the flute profile board. A double idler wheel block is installed in adjacency to the flute profile board. The double idler wheel block is connected to the output shaft of the gear decelerating mechanism. The idler wheel block rotates positively and negatively under control of the output shaft of the gear decelerating mechanism. The idler wheel can be embedded in to the flute profile gaps of the flute profile board to change location by dialing the flute profile board so as to make it present separation position, closing position and grounding position. Switch separation, closing and grounding actions are implemented by the main output shaft. The utility model controls three working positions through the same main output shaft. It is characterized by large gearing moment, long life, stable operation, small size, easy operation and robust anti misconduct function.

Description

A kind of general tri-station isolating switch hand, electric dual-purpose operating mechanism

Technical field

The utility model relates to the electric switch technical field, especially relates to the operation driving mechanism in the electric switch.

Background technology

The operating mechanism of isolating switch hand, electric dual-purpose can only be finished the operation of combined floodgate or separating brake at present, and in actual applications, be security consideration, also need carry out ground connection, promptly by the electric power system regulation, the operation sequence of circuit breaker, isolating switch will meet five anti-requirements, can finish like this close, branch, the hand of three complete actions of station of ground connection, electric dual-purpose operating mechanism be still blank so far.

Summary of the invention

The purpose of this utility model is in order to overcome the deficiency of above-mentioned prior art, a kind of volume is little, operation is simple and reliable, the faulty action preventing function is strong general tri-station isolating switch hand, electric dual-purpose operating mechanism to be provided.

For achieving the above object, the technical solution adopted in the utility model is such: a kind of general tri-station isolating switch hand, electric dual-purpose operating mechanism comprise motor and transmission mechanism, actuator and peripheral electric control system; Motor connects gear reduction, and the output main shaft is installed on frame, and output main shaft one end links to each other with the isolator operation arm by connecting lever, connecting rod; On the output main shaft, a trough plate is housed, is evenly equipped with four grooves on the half cycle face of trough plate and lacks; Establish one with matching pair of roller block near trough plate, this pair roller block connects with the output shaft of gear reduction, and the output shaft of gear reduction is high and parallel together with the output main shaft; Two rollers on two roller blocks and the output shaft of gear reduction are equilateral triangle and arrange, when the positive and negative rotation of the output shaft of gear reduction, make roller block with the positive and negative rotation of axle, can occur in the rotation process during groove that roller embeds trough plate lacks, stir trough plate and change the position, make it to present respectively separating brake position, closing position and earthing position, realize separating brake, combined floodgate and landing operation by the output main shaft;

Also be connected with isolation handle and ground connection handle interface at the output spindle nose, when the need manual operation,, the output main shaft put in place at once as long as connect operating grip by station.

Owing to adopted technique scheme, a kind of general tri-station isolating switch hand of the present utility model, electric dual-purpose operating mechanism are handled three stations with same output main shaft; Adopt the structure of two rollers, trough plate, its driving torque is big, and the life-span is long, operates steadily, and has the advantages that volume is little, operation is simple and reliable, the faulty action preventing function is strong, can be used for indoor or the interior isolating switch of cabinet.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the left-hand cutaway view that Fig. 1 removes frame side wall.

Fig. 4-Figure 10 is that 6 pairs of roller blocks of the utility model parts cooperate the transmission schematic diagram with parts 9 trough plates; Wherein Fig. 4 is a closing position, and Fig. 7 is the separating brake position, and Figure 10 is an earthing position.

Among the figure: 1, frame, 2, motor, 3, the output main shaft, 4, reducing gear, 5, roller, 6, two roller block, 7, the output shaft of gear reduction, 8, groove lacks, 9, trough plate, 10, dead electricity manual unlocking hole.

Embodiment

Contrast accompanying drawing 1--3, a kind of general tri-station isolating switch hand of the present utility model, electric dual-purpose operating mechanism comprise motor and transmission mechanism, actuator and peripheral electric control system; Motor 2 connects gear reduction 4, and output main shaft 3 is installed on frame 1, and output main shaft one end links to each other with the isolator operation arm by connecting lever, connecting rod; On the output main shaft, a trough plate 9 is housed, is evenly equipped with four grooves on the half cycle face of trough plate and lacks 8; Establish one with matching pair of roller block 6 near trough plate, this pair roller block connects with the output shaft 7 of gear reduction, and the output shaft 7 of gear reduction is high and parallel together with output main shaft 3; Two rollers 5 on two roller blocks are equilateral triangle with the output shaft of gear reduction and arrange;

Contrast accompanying drawing 4--10, when the positive and negative rotation of the output shaft of gear reduction, just roller block 6 is with axle 7 positive and negative rotations, and the groove that can occur roller 5 embedding trough plates in the rotation process lacks in 8, stirs trough plate and changes the position; , counterclockwise each three-sixth turn suitable at two roller blocks, trough plate can present separating brake position, closing position and earthing position respectively, realizes separating brake, combined floodgate and landing operation by output main shaft 3;

Said motor 2 is a kind of open type, tandem AC/DC high-speed electric expreess locomotive;

Said reducing gear 4 adopts the transmission of Pyatyi reduction gearing;

Also be connected with isolation handle and ground connection handle interface in output main shaft 3 ends, when the need manual operation,, the output main shaft put in place at once as long as connect operating grip by station;

Electrical control division of the present utility model is assigned components and parts such as three station change over switches, relay, travel switch, and the interlock that combines with mechanical part, dead electricity manual unlocking device etc., on frame side wall, be provided with dead electricity manual unlocking hole 10, it be used for when electric operating not in place, promptly export main shaft not just in time close, branch, earthing position, and can't proceed electric operating, the direct drive mode of employing because of the dead electricity reason.
