Abstract
The present invention relates to an overvoltage protector. Because the size of a lightening arrester in a traditional overvoltage protector is large, a big cabinet is required to hold the overvoltage protector, and it is difficult to combine a plurality of lightening arresters together for application; and the occupied space is large if the lightening arresters are combined together, it is difficult to satisfy the requirement at occasions, and the installation and maintenance are inconvenient in the usage process. The overvoltage protector provided by the invention comprises lightening arresters which have upper terminals and lower terminals, and the lightening arresters are characterized in that: there are at least two lightening arresters, an insulation base plate configured to connect the lightening arresters into one body is arranged at the lower portions of the lightening arresters, the insulation base plate is provided with a ground terminal, and the ground terminal is connected with the lower terminals of each lightening arrester. The overvoltage protector is small in size, saved in space, small in dimension and convenient for installation and wiring, and is especially suitable for switch cabinets with limited space and the like.
Description
Technical field
The present invention relates to a kind of overvoltage protection device.
Background technology
Spark gap in conventional voltage protector is larger in size; very big switch cubicle is needed to be held; and be difficult to multiple spark gaps are combined application; if combined, take up room big; it is difficult to meet the demand of most occasions now, in use installs and maintenance is also inconvenient.
Summary of the invention
The technical problem to be solved is to provide the overvoltage protection device of a kind of smaller size smaller that can be placed in switch cubicle.
For solving above-mentioned technical problem; the technical solution adopted in the present invention is: a kind of overvoltage protection device; including spark gap; it has upper terminals and lower terminals; it is particular in that: the quantity at least two of described spark gap; its underpart is provided with the insulating base connected as one by multiple spark gaps, and described insulating base is provided with earth terminal, and described earth terminal is connected with the lower terminals of each spark gap.
The quantity of described spark gap is three.
Described lower terminals are connected by silicon rubber lead with earth terminal, and organic composite material selected by spark gap.
Compared with prior art, the multiple spark gaps that the invention have the benefit that in the present invention are set to integrative-structure, small volume by insulating base, save space, compact size, install and easy-to-connect, be particularly well-suited to the switch cubicle etc. of limited space；Wire between upper terminals and electrical network is silicon rubber lead, and lower wire between terminals and earth terminal is also silicon rubber lead, and spark gap selects organic composite material, not only favorable sealing property, and dielectric strength is high, is omitted multinomial tedious work.
Accompanying drawing explanation
The present invention is described in detail below in conjunction with drawings and embodiments:
Fig. 1 is the structural representation of the present invention.
In figure: 1. spark gap；2. go up terminals；3. insulating base；4. earth terminal.
Detailed description of the invention
As shown in Figure 1; a kind of overvoltage protection device; including spark gap 1; it has upper terminals 2; the number of bits of described spark gap 1 three; its underpart is provided with the insulating base 3 connected as one by multiple spark gaps 1, and described insulating base 3 is provided with earth terminal 4, and described earth terminal 4 is connected with the lower terminals 3 of each spark gap 1.
The operation principle of the present invention is: be connected with electrical network by the upper terminals 2 of each spark gap 1, earth terminal 4 ground connection or connect enumerator, when electrical network suffers the impact of overvoltage, spark gap 1 moment can produce very big dash current, this dash current is discharged in the earth by earth terminal, thus protecting other equipment to exempt from infringement, wire between upper terminals 2 and electrical network is silicon rubber lead, wire between spark gap 1 and earth terminal 4 is also silicon rubber lead, organic composite material selected by spark gap 1, not only favorable sealing property, dielectric strength is high, it is omitted multinomial tedious work.This combination can not only have a good voltage protection effect, and compact conformation, smaller, install and easy-to-connect, be particularly well-suited to the switch cubicle etc. of limited space.
The foregoing is only the better embodiment of the present invention; protection scope of the present invention is not limited with above-mentioned embodiment; in every case those of ordinary skill in the art modify or change according to the equivalence that disclosed content is made, and all should include in the protection domain recorded in claims.
