Abstract
The utility model relates to an external device of anti thunderbolt ware earth connection of street lamp power, street lamp power have confined metal casing, are equipped with the hole that supplies the wire to pass before the shell on the terminal surface, and the wire is connected with the inside anti thunderbolt absorber of street lamp power, the wire passes the preceding terminal surface of shell from inside to outside to be connected through terminal surface detachable before locking device and the shell, when carrying out lightning surge and EMC when test, pass through locking device and shell with the wire before the terminal surface is connected, make to resist the absorber ground connection of being struck by lightning, when the experiment of the 2U+1000V's that carries out safe pattern dielectric strength, with terminal surface separation before wire and the shell. The utility model discloses an external device of anti thunderbolt ware earth connection of street lamp power makes the street lamp power in the authentication of application CCC, inspects the test by ready samples and only need provide a style, censorship style commonality improves greatly, efficiency of software testing improves to some extent, locking device locking and split are adjusted very conveniently, have improved tester's convenience, the design concept is ingenious, and the preparation is convenient.
Description
Technical field
The utility model relates to a kind of anti-lightning device ground wire external device of road lamp power supply, belongs to road lamp power supply technical field.
Background technology
Road lamp power supply is owing to being positioned over open air, therefore anti-lightning performance is an important performance indexes, and the general all built-in anti-lightning absorber of existing road lamp power supply, therefore instantaneously when thunder and lightning hits road lamp power supply, instant high-voltage can be sponged by anti-lightning absorber, guarantees the security performance of LED street lamp.
The security performance test of road lamp power supply is except anti-lightning test, also has the dielectric strength experiment of the 2U+1000V of safe pattern, when carrying out, dielectric strength is real-time, because the test duration lasts 1 minute, and anti-lightning absorber cannot bear high voltage so for a long time, cannot pass through to making this test.
Therefore, existing solution is: when doing CCC certification sample censorship test, one is provided to be with anti-lightning absorber and a road lamp power supply not with anti-lightning absorber respectively, when carrying out anti-lightning test and other tests, using the road lamp power supply of band anti-lightning absorber, carrying out, when carrying out dielectric strength experiment, adopting the road lamp power supply not with anti-lightning absorber, censorship is caused to test needs two styles, very inconvenient.
Utility model content
The purpose of this utility model is: the anti-lightning device ground wire external device providing a kind of road lamp power supply, be integrated on road lamp power supply, same road lamp power supply can be used, carry out anti-lightning strike test, dielectric strength experiment and other a series of tests, improve the versatility of test model.
The utility model takes following technical scheme:
An anti-lightning device ground wire external device for road lamp power supply, described road lamp power supply has closed shell, and case nose face is provided with the hole passed for wire 2, and described wire 2 is connected with the anti-lightning absorber 1 of road lamp power supply inside; Described wire 2 from inside to outside through case nose face, and is connected with case nose face is dismountable by locking device; When carrying out lightning surge and EMC test, described wire 2 being connected with case nose face by locking device, making anti-lightning absorber 1 ground connection; When carrying out the dielectric strength experiment of 2U+1000V of safe pattern, described wire 2 is separated with case nose face.
When carrying out dielectric strength experiment: anti-lightning absorber can not ground connection, is therefore untied by locking device, make wire not contact with case nose face.
When carrying out other tests except dielectric strength experiment; when especially carrying out lightning surge test: wire is fixedly connected with case nose face; make anti-lightning absorber ground connection, make anti-lightning absorber in power supply absorb lightning surge voltage, do not damage with other components and parts of protection power source.
Further, the front end face of described shell is detachable end face.
Further, described locking device is bolt nut structure 3, and the front end of described wire 2 connects conducting strip, for being compressed the front end face being fitted in described shell by nut.
Further, the rectangular body structure of described road lamp power supply.
The beneficial effects of the utility model are:
1) road lamp power supply censorship test only need provide a style.
2) censorship style versatility improves greatly.
3) testing efficiency increases.
4) locking device locking and fractionation regulate very convenient, improve the convenience of tester.
5) design concept is ingenious, easy to make.
6) drop into little, obviously do not increase cost.
