Abstract
Provided is a composite insulator. The utility model mainly solves problems that overvoltage damages terminal electric equipment or causes breakers to trip in a high voltage electricity transmission process. The composite insulator is characterized in that an upper terminal (1) is fixed with an arc striking arm (4) which extends out in a side direction and bends downward vertically. A lower terminal (2) is fixed with an arcing arm (5) which extends out in the side direction and bends upward vertically. A bend portion of the arc striking arm (4) and a bend portion of the arcing arm (5) are on a same line. A bend portion tip of the arc striking arm (4) and a bend portion tip of the arcing arm (5) are respectively provided with a first ball (6) and a second ball (7). A certain space is disposed between the first ball (6) and the second ball (7). The composite insulator is added with the arc striking arm and the arcing arm. When overvoltage occurs in a circuit, a discharge access is formed between the arc striking arm and the arcing arm, without damaging the terminal electric equipment or causes breakers to trip. The composite insulator is safe and reliable.
Description
Technical field
The utility model relates to a kind of electric armour clamp, is specifically related to a kind of composite insulator.
Background technology
In electric power system, generally to adopt aerial cable to carry out high-tension electricity to carry, aerial cable is fixed on insulator, insulator is fixed on pylon again, existing insulator mainly is comprised of insulation mandrel, upper terminal, lower terminal and umbrella cover, when overvoltage occurring in circuit, can endanger the terminal power consumption equipment, or cause circuit breaker tripping, affect the normal electricity transmission of electrical network.
The utility model content
In order to solve high-tension electricity course of conveying overvoltage injury terminal power consumption equipment or to cause the problem of circuit breaker tripping, the utility model provides a kind of composite insulator, this composite insulator has increased the striking arm and has recruited the arc arm, when overvoltage occurring in circuit, can form discharge path between striking arm and trick arc electrode, can not endanger the terminal power consumption equipment or cause circuit breaker tripping, safe and reliable.
The technical solution of the utility model is: a kind of composite insulator, comprise upper terminal, lower terminal and umbrella cover, be fixed with the striking arm on upper terminal, the striking arm extends laterally and bending downward vertically, be fixed with on lower terminal and recruit the arc arm, recruit the arc arm to extend laterally and upwards vertical bending, the kink of trick arc arm and the kink of striking arm are on same straight line, the kink termination of striking arm and recruit the kink termination of arc arm to be respectively equipped with the first bulb and the second bulb has certain spacing between the first bulb and the second bulb.
Between described the first bulb and the second bulb, distance is 170mm～190mm.
Described striking arm and trick arc arm are fixed on upper terminal and lower terminal by the first buckle and the second buckle respectively.
The utlity model has following beneficial effect: owing to taking such scheme, when overvoltage occurring in circuit, can form discharge path between striking arm and trick arc arm, make in conveying circuit and can not surpass the voltage of setting, can not endanger the terminal power consumption equipment or cause circuit breaker tripping, safe and reliable.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
1-upper terminal in figure, the 2-lower terminal, the 3-umbrella cover, 4-striking arm, 5-recruits arc arm, 6-the first bulb, 7-the second bulb, 8-the first buckle, 9-the second buckle.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, a kind of composite insulator, comprise upper terminal 1, lower terminal 2 and umbrella cover 3, be fixed with striking arm 4 on upper terminal 1, striking arm 4 extends laterally and bending downward vertically, be fixed with on lower terminal 2 and recruit arc arm 5, recruit arc arm 5 to extend laterally and upwards vertical bending, the kink of trick arc arm 5 and the kink of striking arm 4 are on same straight line, the kink termination of striking arm 4 and recruit the kink termination of arc arm 5 to be respectively equipped with between the first bulb 6 and the second bulb 7, the first bulbs 6 and the second bulb 7 to have certain spacing.Owing to taking technique scheme, when overvoltage occurring in circuit, can form discharge path between striking arm 4 and trick arc arm 5, make in conveying circuit can not surpass the voltage of setting, can not endanger the terminal power consumption equipment or cause circuit breaker tripping, safe and reliable.
Between described the first bulb 6 and the second bulb 7, distance is 170mm～190mm.Spacing between the first bulb 6 and the second bulb 7 can form discharge loop when overvoltage, still can guarantee the insulation property under normal power-frequency voltage after discharge.
Described striking arm 4 and trick arc arm 5 are fixed on upper terminal 1 and lower terminal 2 by the first buckle 8 and the second buckle 9 respectively.Striking arm 4 and trick arc arm 5 make this insulator can be used as common insulator and use for removably connecting, and can install again striking arm 4 and recruit arc arm 5 to realize overvoltage protection, use flexible, easy for installation.
