Abstract

An insulator string electric arc discharging device comprises electrodes of parallel-connected air gaps for discharging electric arc, an insulator string and hardware fittings. Two ends of the insulator string are provided with the hardware fittings; the hardware fittings are fixedly provided with the electrodes of parallel-connected air gaps for discharging electric arc. The space between the discharging air gaps remains at almost the same; the space of the discharging air gaps is slightly smaller than the length of the insulator string; the space between polar axes is approximately twice as much as the diameter of a porcelain insulator. The hardware fittings at the two ends of the insulator string are respectively connected with an electric transmission line on one end and with the hardware fittings of a pole fixed insulator on the other end. The device can be arranged on lines of 35KV, 110KV and 220KV. The utility model has the benefits that as the parallel-connected air gaps for discharging electric arc are arranged at the two ends of the insulator string, electric arcs caused by thunderbolt burn in the air gaps for discharging electric arc that are far away from the surface of the insulator, thus protecting the insulator and the affiliated fixed hardware fittings.

Description

A kind of insulator string electric arc bleeder
Technical field
The utility model relates to a kind of insulator string electric arc bleeder, belongs to electric power system, High-Voltage Insulation field.
Background technology
The electric power system overhead transmission line is laid in the open air.In the fault of whole overhead transmission line, the accident that thunderbolt causes accounts for more than 30%.The thunderbolt circuit often causes insulator string surface that flashover takes place, and then the power frequency continued flow electric arc of Chi Xuing burns along insulator surface, thus may cause the insulator porcelain vase cracked with and attached fixedly gold utensil damage and develop into line fault, tripping operation is cut off the power supply.The element of searching fault point, replacing damage after the fault causes the long period to have a power failure, and has reduced power supply reliability and has increased operating cost.
Summary of the invention
For overcome existing insulator technology structure in this respect deficiency, the utility model provides a kind of insulator string electric arc bleeder.
The technical scheme that its technical problem that solves the utility model adopts is: comprise electric arc in parallel release air gap electrode, insulator string, gold utensil, gold utensil is equipped with at the insulator string two ends, and the electric arc in parallel air gap electrode of releasing fixedly is housed on the gold utensil.The discharge air-gap gap length is slightly less than the long length of string of insulator string, insulator string two ends gold utensil, and an end is connected with transmission line; The gold utensil of the other end and shaft tower fixed insulation joins.This device can be installed on 35KV, 110KV, 220KV circuit.
Benefit of the present utility model is, adds the electric arc in parallel air gap of releasing at the two ends of insulator string, and the electric arc that thunder and lightning is caused burns in the air gap of releasing away from the electric arc of insulator surface, thereby has protected insulator and attached fixedly gold utensil.
Description of drawings
Fig. 1 is the structure front view of this device.
Below in conjunction with drawings and Examples utility model is further specified.
Embodiment
Embodiment 1: a kind of as shown in Figure 1 insulator string electric arc bleeder, comprise electric arc in parallel release air gap electrode 1, insulator string 2, gold utensil 3, and an axle die opening is a, the discharge air-gap spacing is b.Gold utensil 3 is equipped with at insulator string 2 two ends, and the electric arc in parallel air gap electrode 1 of releasing fixedly is housed on the gold utensil 3.Discharge air-gap spacing b length is slightly less than the long length of string of insulator string 2, and axle die opening a is approximately 2 times of porcelain vase diameter.Insulator string 2 two ends gold utensils 3, one ends are connected with transmission line; The gold utensil of the other end and shaft tower fixed insulation joins, and has good ground connection performance.
Embodiment 2: this device can be installed on 35KV, 110KV, 220KV circuit, and concrete discharge air-gap spacing b and axle die opening a will look actual transmission line situation test and determine.
