Abstract
A kind of lightning-arrest effective, structure simple, be easy to the building tower crane equipotential ring type lightning arrester installing and use, it is made up of conduction rack and equipotential ring, conduction rack is made up of the conductor substring of the taper and bottom that are positioned at its top, equipotential ring is positioned at below conduction rack, its inside has lightning protection to strike back net, and lightning protection counterattack net is in parallel and connect into netted composition by the capacitor of several different capabilities value.Between conduction rack and equipotential ring and equipotential ring lower end has conductor substring and equipotential ring tie point and equipotential ring and tower crane earth connection tie point respectively, when building tower crane induction obtain be low-frequency induction overvoltage time, the direct ground connection of single-point is formed by equipotential loop wire, when high-frequency, utilize the high-frequency ac feature of capacitor, Low ESR multi-frequency ground connection is realized by the shunt capacitor of the several different capabilities value of lightning protection counterattack net, thus make the electric charge of different frequency import the earth well, effectively prevent the attack of thunder and lightning.
Description
Technical field
The utility model relates to a kind of building tower crane lightning arrester, especially a kind of building tower crane equipotential ring type lightning arrester.
Background technology
The building tower crane of towering setting is the metal device being often subject to thunder disaster, thunder and lightning is formed at air motion process, the electromagnetic field that thunder and lightning produces mainly through inductively, electromagnetic coupled or electrostatic coupling make building tower crane respond to high-tension electricity, usually be subjected to the attack of thunder and lightning, jeopardize manpower and property safety.For a long time, building tower crane is difficult to protect because of lightning induction high-tension electricity is the outstanding problem that building trade exists always.At present, domestic also have some construction sector on tower crane, use a kind of simple sharp item lightning arrester, but this simple pinnacle lightning arrester release electricity is fast not, and lightning-arrest effect is bad.As a kind of building tower crane equipotential ring type lightning arrester described in the utility model has no report.
Summary of the invention
It is fast not that the simple pinnacle lightning arrester used to overcome existing building tower crane discharges electricity, the deficiency that lightning-arrest effect is bad, the utility model provides a kind of building tower crane equipotential ring type lightning arrester, and this utility model is not only lightning-arrest effective, and structure is simple, be convenient to install and use.
The utility model solves the technical scheme that its technical problem adopts: a kind of building tower crane equipotential ring type lightning arrester is made up of conduction rack and equipotential ring, conduction rack comprises taper and conductor substring, taper is positioned at conduction rack top, conductor substring is positioned at below taper, and conductor substring bottom is conductor substring and current potential ring tie point.Equipotential ring is positioned at conduction rack bottom, its inside is provided with lightning protection counterattack net, lightning protection counterattack net is in parallel and connect into netted composition by the capacitor of several different capabilities value, there are equipotential ring and tower crane earth connection tie point in equipotential ring lower end, and the lightning protection counterattack net of taper, conductor substring, equipotential ring and inside thereof is formed by ferrous material.Tower crane equipotential ring type lightning arrester is arranged on the tower arm two ends of building tower crane.When the charge inducing on tower crane after thundercloud discharge is released at once, form a large amount of free charges, shove to tower arm two ends, what the equipotential ring type lightning arrester being at this moment arranged on tower arm two ends utilized capacitor is easy to logical high-frequency ac electrical characteristics, just can the various induced voltages of the different frequency of tower crane induction be drained into the earth afterwards with the capacitor parallel connection of the several different capabilities values in equipotential ring, namely when low frequency, the direct ground connection of single-point is formed by equipotential loop wire, when high frequency, capacitor is utilized to lead to high-frequency ac feature, Low ESR multi-frequency ground connection is realized by the shunt capacitor of several different capabilities value in lightning protection counterattack net, the electric charge of the different frequency so just making tower arm respond to well imports the earth, play safety guarantee effect.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is a kind of structure chart of building tower crane equipotential ring type lightning arrester.
Fig. 2 is the position that a kind of building tower crane equipotential ring type lightning arrester is arranged on tower crane.
In figure 1, tower crane equipotential ring type lightning arrester, 2, taper, 3, conductor substring, 4, conductor substring and equipotential ring tie point, 5, equipotential ring, 6, capacitor, 7, lightning protection counterattack net, 8, equipotential ring and tower crane earth connection tie point, 9, tower crane, 10, tower arm, 11, tower crane earth connection.
