Description

A kind of Residential Area spark gap

Technical field

This utility model belongs to protective equipment technical field, is specifically related to a kind of Residential Area spark gap.

Background technology

Spark gap is again surge protector, and its effect is that the instantaneous overvoltage of ingress signal transmission line is limited in equipment Or in the voltage range that can bear of system, or powerful thunder-strike current is introduced the earth, make protected equipment or system not Cause is hit and damages, and spark gap is the indispensable a kind of thunder-lightning equipment of microwave communication electronic equipment.Spark gap generally connects Being connected between wire and ground, in parallel with by protection equipment, when overvoltage value reaches the operation voltage of regulation, spark gap moves immediately Make, flow through electric charge, over-voltage amplitude, protect apparatus insulated；After magnitude of voltage is normal, spark gap restores to the original state the most rapidly, is System normal power supply, wherein the residual voltage of spark gap is an important electrical specifications, and residual voltage is the lowest, and the level of protection of spark gap is more Height, and apply to now the spark gap in communication base station antenna-feedback system and typically use the resistance high-frequency signal of 1/4 wavelength to lead to directly Stream electricity characteristic realize, fully rely on short circuit inner wire to big electric current of releasing, therefore residual voltage is of a relatively high.

The spark gap of prior art, lightning-arrest effect is bad, can bring the biggest loss to resident, and television set is easily by thunder Electric shock hits, accordingly, it would be desirable to improve prior art.

Utility model content

The purpose of this utility model is to provide a kind of Residential Area spark gap, to solve proposition in above-mentioned background technology Problem.

For achieving the above object, this utility model following technical scheme of offer: a kind of Residential Area spark gap, including sleeve pipe And earth lead, described inside pipe casing upper end is provided with spark ring, and described spark ring is arranged below resistor disc, described spark ring and electricity Resistance sheet is electrically connected with, and described earth lead is electrically connected with through spark ring and resistor disc with adapter, and described adapter is arranged on Jacket exterior top, described adapter is provided with lightning-arrest needle ring, and described lightning-arrest needle ring includes that shading ring, secondary discharging rod, master take shelter from the thunder Pin, conductor and adpting flange, described secondary discharging rod is arranged on above shading ring, and described main discharging rod is arranged on shading ring center, Described conductor is arranged on below main discharging rod, and described conductor is connected by adpting flange and adapter are fixing.

Preferably, described secondary discharging rod is set to three groups.

Preferably, described lightning-arrest needle ring is provided in round.

Technique effect of the present utility model and advantage: this Residential Area spark gap, can get the biggest by main discharging rod A part of voltage, can get remaining voltage by secondary discharging rod, is transported to by thunder and lightning in the earth, this utility model, structure Simply, lightning-arrest effective, easy to process, cost of manufacture is low, is effectively protected the safety of resident.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model；

Fig. 2 is detonation configuration schematic diagram of the present utility model.

In figure: 1 sleeve pipe, 2 spark rings, 3 resistor discs, 4 earth leads, 5 adapters, 6 take shelter from the thunder needle ring, 61 shading rings, 62 secondary Discharging rod, 63 main discharging rod, 64 conductors, 65 adpting flanges.

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise The every other embodiment obtained, broadly falls into the scope of this utility model protection.

This utility model provides a kind of Residential Area spark gap as shown in Fig. 1 and Fig. 2, leads including sleeve pipe 1 and ground connection Line 4, described sleeve pipe 1 inner upper end is provided with spark ring 2, and described spark ring 2 is arranged below resistor disc 3, described spark ring 2 and resistance Sheet 3 is electrically connected with, and described earth lead 4 is electrically connected with through spark ring 2 and resistor disc 3 with adapter 5, and described adapter 5 sets Putting in sleeve pipe 1 outer tip end, described adapter 5 is provided with lightning-arrest needle ring 6, and described lightning-arrest needle ring 6 includes that shading ring 61, pair are lightning-arrest Pin 62, main discharging rod 63, conductor 64 and adpting flange 65, described secondary discharging rod 62 is arranged on above shading ring 61, and described master keeps away Thunder pin 63 is arranged on shading ring 61 center, and described conductor 64 is arranged on below main discharging rod 63, and described conductor 64 passes through connection method Orchid 65 is fixing with adapter 5 to be connected.

Further, described secondary discharging rod 62 is set to three groups.

Further, described lightning-arrest needle ring 6 is provided in round.

This Residential Area spark gap, can get voltage greatly by main discharging rod 63, by secondary discharging rod 62 Remaining voltage can be got, thunder and lightning is transported in the earth, this utility model, simple in construction, lightning-arrest effective, processing side Just, cost of manufacture is low, is effectively protected the safety of resident.

Last it is noted that the foregoing is only preferred embodiment of the present utility model, it is not limited to this Utility model, although being described in detail this utility model with reference to previous embodiment, for those skilled in the art For, the technical scheme described in foregoing embodiments still can be modified by it, or to wherein portion of techniques feature Carry out equivalent, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all Within protection domain of the present utility model should be included in.
