Abstract

The utility model relates to a drop indication type lightning protection gap which comprises a gap high-voltage electrode, a gap grounding electrode, a drop-indicating rod, a fuse wire, a connecting hardware fitting, a fixing part and other accessories and is designed for the frequently happened lightning stroke discharge accidents of a power transmission line. A lightning stroke discharge channel is formed between the gap high-voltage electrode and the gap grounding electrode to cause lightning stroke to flash over along the gap and to shift and lead power-frequency arc root to leave an insulator end part, so that an insulator and the power transmission line can be protected from damage, the success of reclosure is ensured, the lightning stroke flashover becomes a transient fault, and the normal power supply of an electric network is guaranteed. When a lightning stroke discharge accident occurs on the lightning protection gap, one end of the drop indicating rod installed on the gap high-voltage electrode or the gap grounding electrode drops off to indicate the occurrence of the lightning stroke discharge, so that the monitoring on conditions of the lightning stroke discharge on the line can be performed. The drop indication type lightning protection gap not only can effectively solve the problem of the lightning stroke discharge of the power transmission line and can accurately indicate whether the lightning stroke discharge occurs or not at the same time so as to provide powerful data for analysis of the lightning stroke discharge on the power transmission line.

Description

A kind of indicator type lightning protection inter space that falls
Technical field:
The utility model relates to a kind of indicator type lightning protection inter space that falls, and is used to solve the lightning discharge accident that ultra-high-tension power transmission line takes place frequently.
Background technology:
The lightning discharge of transmission line is one of problem that influences the line security operation always.China's electrical network is being carried out extensive work aspect the transmission line lightning protection transformation in recent years, and lightning outage rate is totally on a declining curve; But transmission line caused by lightning strike still can not be avoided fully, and the circuit thunderbolt causes the phenomenon idol of insulator string breakage that generation is arranged.
The lightning protection measures of extensively taking in the net comprises reduction earth resistance, reinforced insulation, installs tower head lightning rod and ground wire lightning protection side pin additional, leakage conductor or the like is installed at present, its purpose all is in order to increase shield effectiveness, raising line lightning resisting level, the reduction tripping rate with lightning strike to lead, from belonging to the lightning protection measures of " obstruction type " inwardly.But because the randomness and the complexity of lightening activity, and the diversity and the otherness of transmission line corridor landform meteorological condition, make above-mentioned measure exist various problems when using at the scene, be difficult to form effective measures.
Summary of the invention:
The utility model is exactly the deficiency that the technical problem that will solve overcomes above-mentioned technology exactly; a kind of indicator type lightning protection inter space that falls is provided; indication discharge scenario when protection insulator and transmission line are avoided being struck by lightning; can effectively solve the lightning discharge problem of transmission line, improve the safety operation level of circuit.
The utility model designs at the lightning discharge accident that transmission line takes place frequently.Form the lightning discharge passage between gap high-field electrode and the gap ground electrode; make thunderbolt along the gap flashover; and shift, dredge power frequency arc arc root and leave the insulator end; protection insulator and transmission line are not damaged; reclosing can be successful; thereby make lightning stroke flashover become transient fault, guarantee the electrical network normal power supply.When on lightning protection inter space lightning discharge taking place, indicating arm one end of installing on gap high-field electrode or the gap ground electrode that falls falls, thereby the generation of indication lightning discharge is monitored circuit lightning discharge situation.Fall the lightning discharge problem that the indicator type lightning protection inter space can not only effectively solve transmission line, accurately indicate whether to take place simultaneously lightning discharge and analyze the strong data that provides for the transmission line lightning stroke discharge.
A kind of indicator type lightning protection device that falls according to the utility model provides comprises gap high-field electrode, gap ground electrode, falls indicating arm, annex such as fuse, connection gold utensil and fixture, it is characterized in that:
The described indicating arm that falls is installed on gap high-field electrode or the gap ground electrode.
