Abstract
A kind of lightning-arrest effect is good, simple in structure, the building tower crane equipotential ring type arrester that is easily installed and uses, it is made of conduction rack and equipotential ring, conduction rack is made of the conductor substring of taper and lower part positioned at its top, equipotential ring is located at below conduction rack, there is lightning protection to strike back net inside it, lightning protection strikes back net and reticulated and formed by the capacitor parallel connection and connection of several different capabilities values.Between conduction rack and equipotential ring and equipotential ring lower end has conductor substring to be grounded line connection point with tower crane with equipotential ring tie point and equipotential ring respectively, when building tower crane incude be low-frequency induced overvoltage when, single-point is formed by equipotential loop wire to be directly grounded, in high-frequency, utilize the high-frequency ac feature of capacitor, the shunt capacitor that several different capabilities values are netted by lightning protection counterattack realizes Low ESR multi-frequency ground connection, to make the charge of different frequency import the earth well, it is effectively prevented the attack of thunder and lightning.
Description
Technical field
The present invention relates to a kind of building tower crane lightning arrester, especially a kind of building tower crane equipotential ring type arrester.
Background technology
The building tower crane of towering setting is the metal device for being subjected to thunder disaster, and thunder and lightning is formed in air motion process,
Electromagnetic field caused by thunder and lightning mainly by inductively, electromagnetic coupling or electrostatic coupling so that building tower crane is incuded high-voltage electricity,
The attack for often suffering from thunder and lightning jeopardizes manpower and property safety.For a long time, building tower crane is difficult due to lightning induction high-voltage electricity
The outstanding problem existing for protection always building trade.Currently, domestic, there are also construction sector on tower crane using a kind of
Simple point item arrester, but this simple pinnacle arrester release electricity is not fast enough, and effect of taking shelter from the thunder is bad.As described herein
A kind of building tower crane equipotential ring type arrester have not been reported.
Invention content
In order to overcome the simple pinnacle arrester release electricity that existing building tower crane uses not fast enough, effect of taking shelter from the thunder is bad
Deficiency, the present invention provides a kind of building tower crane equipotential ring type arrester, and invention effect of not only taking shelter from the thunder is good, and structure letter
It is single, it is easily installed and uses.
The technical solution adopted by the present invention to solve the technical problems is：A kind of building tower crane equipotential ring type arrester by
Conduction rack and equipotential ring composition, conduction rack includes taper and conductor substring, and taper is located at conduction rack top, conductor substring
Below taper, conductor substring lower part is conductor substring and current potential ring tie point.Equipotential ring is located at conduction rack lower part,
Inside is equipped with lightning protection counterattack net, and lightning protection strikes back net and reticulated and formed by the capacitor parallel connection and connection of several different capabilities values,
Equipotential ring lower end has equipotential ring and tower crane to be grounded line connection point, taper, conductor substring, equipotential ring and its inside it is anti-
Thunder counterattack net is made of ferrous material.Tower crane equipotential ring type arrester is mounted on to the tower arm both ends of building tower crane.When
Charge inducing after thundercloud discharge on tower crane is released at once, is formed a large amount of free charge, is shoved to tower arm both ends, at this moment pacify
Equipotential ring type arrester mounted in tower arm both ends is easy to logical high-frequency ac electrical characteristics using capacitor, in equipotential ring
Several different capabilities values capacitor parallel connection after the various induced voltages for the different frequency that tower crane incudes can be drained into big
Ground forms single-point by equipotential loop wire and is directly grounded that is, in low frequency, in high frequency, leads to high-frequency ac spy using capacitor
Point realizes Low ESR multi-frequency ground connection by the shunt capacitor of several different capabilities values in lightning protection counterattack net, thus makes tower
The charge of the different frequency of arm induction imports the earth well, plays the role of safety guarantee.
