Abstract
The invention relates to an anti-lightning device grounding wire external connection device of a street lamp power supply. A street lamp power supply has an enclosed metal housing. A hole for passing of a wire is arranged in the front end face of the housing. The wire is connected with an anti-lighting absorber inside the street lamp power supply. The wire goes through the front end face of the housing from inside to outside and is detachably connected with the front end face of the housing through a locking device. When lightning surge and EMC tests are carried out, the wire is connected with the front end face of the housing through the locking device, and thus the anti-lighting absorber is grounded. When a safety-type 2U+1000V dielectric strength experiment is carried out, the wire is separated from the front end face of the housing. Only one style is provided for inspection test when the power supply applies for CCC authentication, the inspection style universality is raised greatly, and the test efficiency is raised. Locking and discounting of the locking device are convenient to adjust, convenience for test personnel is raised, the design conception is ingenious, and manufacturing is convenient.
Description
Technical field
The present invention relates to a kind of anti-lightning device ground wire external device of road lamp power supply, belong 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.
Summary of the invention
The object of the invention is: the anti-lightning device ground wire external device that a kind of road lamp power supply is provided, 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 present invention 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.
Beneficial effect of the present invention is:
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.
