Abstract
The utility model provides a single-phase electric isolating switch, which comprises a base, an electric push rod arranged on the base, a rotating shaft connected with the electric push rod via a crank arm, two insulating supporters arranged on the base, two static contacting cutters fixed on the insulating supporters, tow movable contacting cutters clamped at both sides of each of the two static contacting cutters via pressure springs and glidingly fit with the two static contacting cutters, and an insulating pull rod having one end connected with the rotating shaft and the other end connected with the movable contacting cutters. The switch uses the electric push rod as an electric mode without the need of a speed reducing mechanism and a ball screw rod, the movable contacting cutters are changed into a directly operating type from a rotary type, and the utility model having the advantages of simple operation, labor saving for pushing, high flow capacity, high reliability and small installation space is suitable for pulling the unit intervals of a transformer station.
Description
Technical field
The utility model relates to a kind of switch, particularly relates to a kind of single-phase electric isolating switch.
Background technology
At present, widely used single-phase electric isolating switch comprises base, an insulation chapelet, electronic propulsive mechanism, insulated tension pole, movable touch knife and quiescent contacting knife.Wherein movable touch knife is a rotary structure, and by the movable touch knife rotation, realization contacts and disjunction with quiescent contacting knife, thereby realizes the closure and the disconnection of switch.Aspect in addition, the electronic mode of switch need be by cover reducing gears, and adopt the ball screw transmission to realize.Complex structure, power consumption is big, volume is big, installing space is bigger.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of simple in structure, propelling is laborsaving, through-current capability is big, reliability is high and installing space is little single-phase electric isolating switch is provided.
The single-phase electric isolating switch of the utility model comprises base, be arranged on the electric pushrod on the base, the rotating shaft that is connected with electric pushrod by connecting lever, be arranged on the insulation of two on a base chapelet, be fixed on two quiescent contacting knifes on the insulation chapelet, two movable touch knifes that two ends are clipped in the quiescent contacting knife both sides and are slidingly matched with it by the contact stage clip, the insulated tension pole that an end is connected with rotating shaft, the other end is connected with movable touch knife.For the branch that demonstrates switch, close the position, base is provided with auxiliary switch, auxiliary switch is connected with connecting lever by pull bar.
The operation principle of the single-phase electric isolating switch of the utility model is when electric pushrod advances left, to drive rotating shaft by connecting lever and clockwise rotate, rotating shaft drives insulated tension pole and clockwise rotates, slide to the right thereby drive movable touch knife, make the quiescent contacting knife disjunction on the movable touch knife and the left side, reach the separating brake purpose; Otherwise, when electronic electric pushrod advances to the right, driving rotating shaft by connecting lever and rotate counterclockwise, rotating shaft drives insulated tension pole and rotates counterclockwise, and slides left thereby drive movable touch knife, makes movable touch knife and left and right stationary contact knife-edge logical, reaches the combined floodgate purpose.Pull bar drives auxiliary switch closure and disjunction when connecting lever rotates, thus by corresponding indicator light demonstrate switch branch, close the position.
The advantage of the single-phase electric isolating switch of the utility model is simple to operate, advance laborsaving, the reliability height, installing space is little, be applicable to each unit interval of traction substation, comprise that main transformer outlet, bus, feeder line, the female connection of shunt capacitance short-circuit detecting, the used time variant voltage instrument transformer of 27.5kV interval etc. are with isolate by stages.
