The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.

In the description of the present application, it is to be understood that the terms "length," "width," "upper," "lower," "top," "bottom," "inner," "outer," and the like are used in the orientations and positional relationships indicated in the drawings for convenience in describing the present application and to simplify the description, but are not intended to indicate or imply that the referenced devices or elements must have a particular orientation, be constructed in a particular orientation, and be operated in a particular manner, and are not to be construed as limiting the present application.

The terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

Further, in the description of the application, when a plurality of identical components are included, the components may be individually referred to by their full numbers (e.g., the first discharge gap F1), and may be collectively referred to by the first part of their numbers (e.g., the first discharge gap F).

Referring to fig. 1 and fig. 2, a gap type lightning arrester according to an embodiment of the present application will now be described. The gap type lightning arrester includes a fixing bracket 100 and a side opening 200, the fixing bracket 100 is provided with a plurality of first inserting grooves 110 and a plurality of second inserting grooves 120 which are alternately arranged, the side opening 200 includes a plurality of insulating members 210, a plurality of first conductors 220 each having a first supporting portion 221 and a first inserting portion 222 which are connected, and a plurality of second conductors 230 each having a second support portion 231 and a second insertion portion 232 connected to each other, the first support portion 221 of each first conductor 220 abuts against the fixed bracket 100 after the first insertion portion 222 of each first conductor 220 is respectively inserted into the corresponding first insertion groove 110, the second insertion portion 232 of each second conductor 230 is respectively inserted into the corresponding second insertion groove 120, the second support portion 231 of each second conductor 230 and the corresponding first support portion 221 are separated to form a first discharge gap, and each insulating member 210 is respectively disposed in the corresponding first discharge gap.

It is worth to be noted that, when the peak current or the peak voltage is generated in the electrical circuit or the communication line due to the external interference, the gap type lightning protection device can rapidly discharge the peak current or the peak voltage to the ground, thereby preventing the electrical equipment from being damaged by the overvoltage. The voltage protection level of the gap type lightning protector is affected by the height and number of the first discharge gaps F. Since the thickness of the insulating members 210 in the side openings 200 determines the height of the first discharge gap F, the thickness of each insulating member 210 may be set according to a safe voltage of an electrical device to be protected, and is not limited thereto. Preferably, when the insulating members 210 have the same thickness, the first discharge gaps F have the same height, so that the impact discharge and power frequency discharge stability of the gap-type lightning arrester can be ensured, and the gap-type lightning arrester has better protection performance for external electrical equipment. The shape of each insulating member 210 may be a rectangular ring, a square ring, a long bar, etc., and is not limited herein. Each insulating member 210 may be made of various materials, such as rubber, ceramic, teflon, high pressure asbestos, etc., and is not limited herein. Since the total number of the first and second conductive bodies 220 and 230 in the discharge module 200 determines the number of the first discharge gaps, the number of the first and second conductive bodies 220 and 230 may be set according to the safety voltage of the electrical equipment to be protected, and is not limited herein. The fixing bracket 100 may have various forms such as a teflon bracket, a PVC bracket, etc., and is not limited thereto.

In another embodiment of the present application, referring to fig. 2 to 4, two second conductive bodies 230 located at two opposite sides of the discharge module 200 are defined as a leading-in electrode body 2301 and a leading-out electrode body 2302 respectively, and the other second conductive bodies 230 are defined as a middle electrode body 2303, and the second inserting portions 232 of the leading-in electrode body 2301 and the leading-out electrode body 2302 respectively extend outward from the corresponding second inserting grooves 120 to form the pins 233.

It is to be noted that the lead-in electrode body 2301 and the lead-out electrode body 2302 are used for electrically connecting an external cable, wherein the lead-in electrode body 2301 is used for electrically connecting a live line (L) or a neutral line (N) of a power distribution system, and the lead-out electrode body 2302 is used for grounding to leak a surge pulse to the ground.

Because graphite has the characteristic of high temperature resistance, the gap type lightning arrester adopting the structure can avoid the burning connection of the adjacent first conductor 220 and the second conductor 230 to influence the protective performance of the gap type lightning arrester.

In another embodiment of the present application, referring to fig. 3 to fig. 5, the gap type lightning arrester further includes a fixing plate 300, the leading electrode body 2301 and the leading electrode body 2302 are both fixedly connected to the fixing bracket 100, and the fixing plate 300 is fixedly connected to the second supporting portion 231 of the leading electrode body 2301 and the second supporting portion 231 of the leading electrode body 2302.

It should be noted that the fixing plate 300 may be made of an insulating material, such as teflon, PVC, etc., and is not limited herein. The fixing plate 300 and the second support portion 231 of the leading electrode body 2301 and the second support portion 231 of the leading electrode body 2302 can be fixedly connected in various ways, such as a snap connection or a threaded connection, which is not limited herein. The leading electrode body 2301 and the leading electrode body 2302 can be fixedly connected with the fixing bracket 100 in various ways, such as a snap connection or a threaded connection, which is not limited herein.

As a specific embodiment, the side of the fixing bracket 100 is provided with two openings 121, the two openings 121 are respectively communicated with the second inserting groove 120 into which the lead-in electrode body 2301 is inserted and the second inserting groove 120 into which the lead-out electrode body 2302 is inserted, and the pin 233 of the lead-in electrode body 2301 and the pin 233 of the lead-out electrode body 2302 are both formed by the corresponding second inserting portion 232 protruding to the side. The lead-in electrode body 2301 and the lead-out electrode body 2302 of the above-described gap type lightning arrester can be respectively fitted into the corresponding second insertion groove 120 from the corresponding opening 121, since the lead-in electrode bodies 2301 and the lead-out electrode bodies 2302 are loaded into the corresponding second insertion grooves 120, the second receiver 231 of the lead-in electrode body 2301 and the second receiver 231 of the lead-out electrode body 2302 each abut against the corresponding insulation 210, i.e. indirectly against the top of the fixed support 100, and the lead wire bodies 2301 and lead wire bodies 2302 both have their pins 233 against the bottom of the fixed support 100, the lead-in electrode body 2301 and the lead-out electrode body 2302 are automatically clamped to the fixing holder 100 after being inserted into the corresponding second insertion groove 120, the other intermediate electrodes 2303 are pressed against the corresponding insulators 210 by the fixing plates 300, so that the entire discharge module 200 can be simply and efficiently assembled on the fixing bracket 100, thereby improving the assembly efficiency of the gap-type lightning arrester.

Alternatively, the fixing plate 300 may be detachably connected to the second receiving portion 231 of each intermediate electrode body 2303, which may improve the structural stability of the device.

In another embodiment of the present application, referring to fig. 3 to 5, the gap type lightning protection device further includes a trigger module 400, the trigger module 400 includes a plurality of high voltage capacitors C for respectively triggering the conduction of the corresponding first discharge gaps F, one end of each high voltage capacitor C is electrically connected to the lead-in electrode 2301, the other end of one part of the high voltage capacitors C is electrically connected to the corresponding first conductor 220, and the other end of the other part of the high voltage capacitors C is electrically connected to the corresponding middle electrode 2303.

It can be understood that when the spike current or spike voltage generated by the external interference is conducted to the lightning protection device, such as the lightning current intrudes from the leading electrode 2301 of the lightning protection device, because the high voltage capacitor C has the characteristic of instantaneous short circuit under the pulse current, the high voltage capacitor C1 is short-circuited and instantaneously conducts the high potential of the lightning to the first conductor 220 connected with it, then the potential difference is generated between the leading electrode 2302 and the first conductor 220 at both sides of the first discharge gap F1, the first discharge gap F1 is broken down, and a part of the energy is discharged to the ground through the leading electrode 2302, then the high voltage capacitor C2 is short-circuited, the potential difference is generated between the first conductor 220 and the middle electrode 2303 at both sides of the first discharge gap F2, the first discharge gap F2 is broken down, and so on, the high voltage capacitors C3 to C7 respectively trigger the conduction from the first discharge gap F3 to the first discharge gap F7, finally, overvoltage directly acts on the first discharge gap F8, the first discharge gap F8 is broken down, all the first discharge gaps F are conducted to form discharge channels, and after lightning current is discharged along the discharge channels, the lightning protection device restores to a high-impedance state again, and then protection of the electrical equipment is restored.

In another embodiment of the present application, referring to fig. 3 to 5, the trigger module 400 further includes a trigger plate 410 and a plurality of elastic pins 420 fixed on the trigger plate 410, wherein the trigger plate 410 is fixedly connected to the leading electrode body 2301 and the leading electrode body 2302; one part of the pogo pins 420 is electrically connected between the corresponding high-voltage capacitor C and the corresponding first conductor 220 and the other part of the pogo pins 420 is electrically connected between the corresponding high-voltage capacitor C and the corresponding intermediate electrode 2303.

The gap type lightning arrester provided by the embodiment is fixed on the trigger plate 410 by arranging the elastic pin 420 with one end fixed and the other end abutted against the corresponding first conductor 220 or the middle electrode body 2303, so that each high-voltage capacitor C of the trigger module 400 is always electrically connected with the corresponding first conductor 220 or the middle electrode body 2303, and the problem that when lightning current flows through the gap type lightning arrester to generate vibration, the gap type lightning arrester is influenced by the open circuit between the trigger module 400 and the discharge module 200 is avoided.

In another embodiment of the present application, referring to fig. 4 and 5, the trigger plate 410 is provided with an electrical connection element 430 and a conducting wire 440 having one end electrically connected to the electrical connection element 430, the electrical connection element 430 penetrates through the trigger plate 410 and is electrically connected to the lead-in electrode body 2301, and each high-voltage capacitor is disposed on the trigger plate 410 and electrically connected to the conducting wire 440, away from the electrical connection ends of each first conductor 220 and each intermediate electrode body 2303.

It should be noted that the electric connecting member 430 may have various forms, such as a bolt, a screw, etc., and is not limited thereto.

In the gap type lightning arrester provided by the embodiment, the electrical connection member 430 can be used as a fastening member to fixedly connect the trigger plate 410 and the lead-in electrode body 2301, and can also be used as an electrical connection member to electrically connect the lead 440 and the lead-in electrode body 2301, so that the structure of the device is simplified, and the production and the assembly are convenient.

By adopting the gap type lightning protection device with the structure, the shell 500 can effectively prevent dust, rainwater and the like from invading into the gap type lightning protection device, the maintenance frequency of the device can be reduced, and the service life of the device can be prolonged.

In another embodiment of the present application, a second discharge gap G is formed between the second mating part 232 of the lead-in electrode body 2301 and the first mating part 222 of the first electrical conductor 220 adjacent to the lead-in electrode body 2301.

It is noted that the fixing holder 100 is provided with a communication groove between the second insertion groove 120 for inserting the lead-in electrode body 2301 and the first insertion groove 110 adjacent to the second insertion groove 120 to form the second discharge gap F9.

It can be understood that when peak current or peak voltage are smaller, only first discharge gap F can be punctured, when peak current or peak voltage is larger, first discharge gap F and second discharge gap G can both be punctured, because second discharge gap G is longer in length, the electric arc that power frequency voltage triggered extinguishes more easily in second discharge gap G, can accelerate the extinction of electric arc in each first discharge gap F, after making this clearance type lightning protection device discharge the thunder and lightning current into ground, resume high impedance state rapidly, and then resume the protection to external electrical equipment rapidly.
