Description
Technical field
The present invention relates to electric power facility field, especially, is a kind of earthing of lightening arrester.
Background technology
For current earthing of lightening arrester, what generally adopt is a fixing metal bar, is generally made up of copper rod, iron staff or alloy bar, directly inserts underground, and its upper end connects lightning arrester.Because underground environment is comparatively severe, therefore easily make earth rod surface be oxidized, earth resistance is increased, as processed this problem not in time, then, when there is thunderbolt, lightning arrester just normally cannot protect electric equipment.And at present for the detection of earth rod earth resistance, need to adopt special equipment to test, this not only comparatively bothers, and can not carry out Real-Time Monitoring to the earth resistance of earth rod, to guarantee that earthing device keeps best ground state in real time.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide a kind of earthing of lightening arrester, this earthing of lightening arrester can real time reaction ground state, to guarantee the fail safe of circuit.
The technical scheme that actualizing technology object of the present invention adopts is: this earthing of lightening arrester comprises earth rod, and described earth rod comprises metal bar, lower metal bar; Described upper metal bar upper end has terminals, and described lower metal bar lower end is taper; Directly do not contact between described upper and lower metal bar, but a serial connection lightning arrester; Described lightning arrester two ends are an instruction string in parallel also, and described instruction string comprises indicating device and the power supply of series connection mutually.
As preferably, described lightning arrester is fixed between described upper metal bar, lower metal bar, coaxial with upper metal bar, lower metal bar, forms a complete earth rod.
As preferably, described lightning arrester is zinc oxide arrester, and structure is fixed, simply, without the need to arc extinguishing.
As preferably, described indicating device is ohmmeter or indicator light.
As preferably, described power supply comprises a mutual inductor be placed on metal bar, and described mutual inductor exports a rectification module to, and described rectification module exports a super capacitor to, the minus earth of described super capacitor, positive pole is by ground connection after a Voltage stabilizing module.
Beneficial effect of the present invention is: this earthing of lightening arrester is without under thunderbolt situation, as as described in upper metal bar, lower metal bar be all in good ground state, then go up between metal bar, lower metal bar by the earth conducting, then described power supply, indicating device, upper metal bar, greatly, lower metal bar form series connection instruction loop, indicating device normally works, and instruction earthing device is in good ground state; And if one or two in upper metal bar, lower metal bar is in Abnormal Grounding state, then in described series connection instruction loop, resistance increases, and causes described indicating device normally to work, then illustrates that earth resistance is abnormal, need to be keeped in repair; On the other hand, when this earthing of lightening arrester is after receiving thunder-strike current, the direct release current over the ground of upper metal bar, and described lightning arrester is after being struck by lightning, immediately conducting also keeps micro-resistance states, makes lower metal bar, upper metal bar form equipotentiality metallic object, jointly release current over the ground, and lightning arrester two ends only keep faint residual voltage, described indicating device, power supply are not threatened; As can be seen here, this earthing of lightening arrester can the ground state of Real-Time Monitoring self, and does not affect its normally lightning-arrest effect.
Accompanying drawing explanation
Fig. 1 is the electrical structure schematic diagram of an embodiment of this earthing of lightening arrester.
Fig. 2 is the structural representation of Fig. 1 embodiment.
Fig. 3 is in this earthing of lightening arrester, the electrical structure schematic diagram of an embodiment of power supply.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1, embodiment illustrated in fig. 2 in, this earthing of lightening arrester comprises earth rod, and described earth rod comprises metal bar 11, lower metal bar 12; Described upper metal bar 12 upper end has terminals 110, and described lower metal bar 12 lower end is taper; Directly do not contact between described upper and lower metal bar, but a serial connection lightning arrester 2; Described lightning arrester 2 two ends are an instruction string in parallel also, and described instruction string comprises indicating device 31 and the power supply 32 of series connection mutually.
It is pointed out that Fig. 1 is only electrical structure schematic diagram, concrete structure is shown in Fig. 2, and wherein, described lightning arrester 2 is fixed between described upper metal bar 11, lower metal bar 12, coaxial with upper metal bar 11, lower metal bar 12, forms a complete earth rod.Described lightning arrester 2 is zinc oxide arrester, and structure is fixed, simply, without the need to arc extinguishing.
In the present embodiment, described indicating device 31 is indicator light; But also can be replaced by ohmmeter, with direct measurement of Grounding Resistance.
Above-mentioned earthing of lightening arrester is without under thunderbolt situation, as as described in upper metal bar 11, lower metal bar 12 be all in good ground state, then go up between metal bar 11, lower metal bar 12 by the earth conducting, its conduction path as shown in phantom in Figure 1, then described power supply 32, indicating device 31, upper metal bar 11, greatly, lower metal bar 12 form series connection instruction loop, indicating device 31 normally works, and instruction earthing device is in good ground state; And if one or two in upper metal bar 11, lower metal bar 12 is in Abnormal Grounding state, then in described series connection instruction loop, resistance increases, and namely earth resistance increases, and causes described indicating device 31 normally to work, then illustrate that earth resistance is abnormal, needs to be keeped in repair; On the other hand, when this lightning arrester 2 earthing device is after receiving thunder-strike current, the direct release current over the ground of upper metal bar 11, and described lightning arrester 2 is after being struck by lightning, immediately conducting also keeps micro-resistance states, makes lower metal bar 12, upper metal bar 11 forms equipotentiality metallic object, jointly release current over the ground, and lightning arrester 2 two ends only keep faint residual voltage, described indicating device 31, power supply 32 are not threatened; As can be seen here, this earthing of lightening arrester can the ground state of Real-Time Monitoring self, and does not affect its normally lightning-arrest effect.
In the embodiment shown in Fig. 1, Fig. 2, described power supply 32 is external power supply, and by two terminals that earth rod is drawn 320,320, ' access described series connection instruction loop, usually, this power supply 32 directly can get the electric power in protected circuit.
In addition to the implementation; described power supply 32 also can get the electric power that earthing device self produces; and make its work as usual when protected down circuitry; now; this power supply 32 comprises a mutual inductor 321 be placed on metal bar 11, and described mutual inductor 321 exports a rectification module 322 to, and described rectification module 322 exports a super capacitor C1 to; the minus earth of described super capacitor C1, positive pole is by ground connection after a Voltage stabilizing module D1.When then earth rod flowing through at every turn big current, will to super capacitor C1 electric energy supplement, make it as indicating device 31 provides electric power, simultaneously due to the setting of described Voltage stabilizing module D1, when described super capacitor C1 is full of, unnecessary electric energy discharges over the ground by Voltage stabilizing module D1, in case super capacitor C1 damages.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
