Abstract
The utility model provides a three-phase lightning protection device, which comprises a housing. A failure indication circuit board and a lightning protection circuit board are arranged inside the housing. The failure indication circuit board and the lightning protection circuit board are connected through a connecting line. The lightning protection circuit board is connected with wiring terminals. The lightning protection circuit board is also connected with a discharge tube. A ground wire is led out from the housing. The discharge tube is connected with the ground wire. The three-phase lightning protection device which has the characteristics of simple structure and convenient use can form a 3 plus 1 lightning protection mode. The three-phase lightning protection device which has good lightning surge protection effects achieves great protection effects.
Description
Technical field
The utility model relates to a kind of lightning protection device, particularly a kind of three phase anti-thunder device.
Background technology
In prior art, as patent ZL 200520016042.0, a kind of lightning protection for power supply is disclosed; The utility model arrange in the chute of lightning protection component one side one can parallel the dropout push rod, a conductive metal sheet is fixing with it, one end of described conductive metal sheet and the joint welding of described lightning protection device brace are fixed, and the other end is fixedly connected with the wire that is connected of lightning protection device; By above-mentioned design; make the utility model reliability in normal use procedure heat of neutralization protection, overcurrent protection process higher; simultaneously because the dropout push rod separates with the lightning protection component position, can prevent that the performance of the lightning protection for power supply that causes because of the lightning protection component heating is unreliable.But this lightning protection device can not form the lightning protection pattern of 3+1, so lightning surge is not had protective effect, protection effect is poor.
The utility model content
The utility model proposes a kind of simple in structurely, easy to use, and can form the lightning protection pattern of 3+1, lightning surge is had good protective effect, the three phase anti-thunder device that protection effect is good.
The technical solution of the utility model is achieved in that
A kind of three phase anti-thunder device, comprise shell, be provided with Indication of Losing Efficacy circuit board and lightning protection circuit plate in described shell, the Indication of Losing Efficacy circuit board is connected by connecting line with the lightning protection circuit plate, the lightning protection circuit plate is connected with binding post, the lightning protection circuit plate is connected with discharge tube, and shell leads to earth connection, and discharge tube is connected with earth connection.
Further, described shell is provided with protective ring, and discharge tube is connected by protective ring with earth connection.
Further, described Indication of Losing Efficacy circuit board is connected with indicator light.
Further, described indicator light is LED light.
Further, described lightning protection circuit plate is connected with piezo-resistance.
Further, described shell is arranged on guide rail card.
Described shell operated by rotary motion only has 18mm wide.
Adopt the three phase anti-thunder device of technique scheme, owing to being provided with Indication of Losing Efficacy circuit board and lightning protection circuit plate in described shell, the Indication of Losing Efficacy circuit board is connected by connecting line with the lightning protection circuit plate, the lightning protection circuit plate is connected with binding post, and the lightning protection circuit plate is connected with discharge tube, and shell leads to earth connection, discharge tube is connected with earth connection, so binding post is welded on the lightning protection circuit plate, an end of discharge tube is connected with earth connection, forms the lightning protection pattern of 3+1; In case run into thunderbolt, can protect power consumption equipment rapidly, lightning surge there is good protective effect, have a volume little, the characteristics such as price is low, and protection effect is good, and is easy to use.Because described shell is provided with protective ring, discharge tube is connected by protective ring with earth connection, so discharge tube and earth connection connection reliability are good, and stable performance.Because described Indication of Losing Efficacy circuit board is connected with indicator light, so indicator light can provide information.Because described lightning protection circuit plate is connected with piezo-resistance, so to presser sensor.Because described shell is arranged on guide rail card, so convenient in carrying.
Description of drawings
