Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
Example 1
This embodiment provides a preferred embodiment, as shown in fig. 1 to fig. 3, an atmospheric electric field instrument lightning arrester, which includes a support rod 1 fixed on the ground, the support rod 1 is used for supporting the device and has a certain distance with the ground, and the support rod is made of insulating material, so as not to affect the normal operation of the lightning arrester. Atmosphere electric field appearance 2 is installed at bracing piece 1 top, bracing piece 1 with be detachable connection between the atmosphere electric field appearance 2, atmosphere electric field appearance 2 is cylindricly, and it divide into inner shell and shell two parts, a plurality of open-ended shielding electrode 3 have all been seted up for top surface and side to the shell, the inner shell is inductive electrode 4, atmosphere electric field appearance 2 is used for measuring atmosphere electric field and change thereof.
The support part 5 is fixed on the support rod 1, and the support part 5 is vertical to the support rod 1. 5 end departments of supporting part install arrester 6, supporting part 5 with be detachable connection between the arrester 6, arrester 6 adopts the zinc oxide arrester, and the zinc oxide arrester has utilized the good non-volt-ampere characteristic of zinc oxide, 6 tops of arrester are high-voltage terminal 7, high-voltage terminal 7 pass through wire 9 with induction electrode 4 connects, 6 bottoms of arrester are earthing terminal 8, earthing terminal 8 passes through wire 9 and is connected with ground. The shape of the support part 5 is not limited, and the lightning arrester 6 is fixed while the high-voltage end 7 is arranged at the upper part and the grounding end 8 is arranged at the lower part along the vertical direction. Under normal operating voltage, only microampere-level current passes through the arrester 6. When thunder hits the device and overvoltage is generated, the resistance value of the lightning arrester 6 is rapidly reduced, and the energy of the overvoltage is discharged, so that the effect of protecting the circuit is achieved. In the practical application of the atmospheric electric field instrument 2, the lightning arrester 6 can be regarded as an insulating state, and does not affect the normal atmospheric electric field measurement.
The working principle of the atmospheric electric field instrument 2 is that the induction electrode 4 and the shielding electrode 3 are mutually cut, so that the electric field is cut, an induction current corresponding to the atmospheric electric field is generated, and the shielding electrode 3 achieves the effect of shielding the electric field by grounding. When thunder hits the atmospheric electric field instrument 2, the main hitting positions are the induction electrode 4 and the shielding electrode 3. Therefore, as shown in fig. 3, when the atmospheric electric field instrument 2 is at the operating voltage, the shielding electrode 3 directly flows to the ground; the current of the induction electrode 4 flows to a signal processing circuit; when the atmospheric electric field instrument 2 is struck by lightning and is in an overvoltage state, current flows to the ground through the zinc oxide lightning arrester. Namely, under the state of not being hit by thunder and lightning, the circuit of the lightning arrester 6 is equivalent to open circuit, and the normal measurement of the atmospheric electric field instrument 2 cannot be influenced; when the atmospheric electric field instrument 2 is hit by lightning, the lightning arrester 6 circuit is equivalent to a short circuit, and high-voltage current is directly grounded through the lightning arrester 6 circuit, so that the atmospheric electric field instrument 2 is protected.
The lightning arrester is convenient to add and suitable for an atmospheric electric field instrument; the lightning arrester is different from an active lightning arrester, adopts a passive lightning arresting mode, and cannot generate an electrostatic field which influences the normal work of an atmospheric electric field instrument.
