Abstract
The invention relates to a dielectric voltage withstand test-used grounding wire device of a street lamp power source with a built-in lightning protection device. The street lamp power source is provided with a sealed metal shell; a hole through which a wire can pass is formed in the front end surface of the shell; the wire is in shorting connection with a circuit board external-connection line welding point of an anti-lightning absorber in the street lamp power source; and the wire passes through the front end surface of the shell from inside to outside and is detachably connected with the front end surface of the shell through a locking device. When a lightning surge and EMC test is carried out, the wire is connected with the front end surface of the shell through the locking device, so that the anti-lightning absorber can be grounded; and when a safety type 2U+1000V dielectric strength test is carried out, the wire is separated from the front end surface of the shell. With the grounding wire device of the invention adopted, when street lamp power sources are to be tested, one test sample is required to be provided only; the universality of the tested test sample is greatly improved; test efficiency can be improved; the wire can be in excellent shorting connection with the anti-lightning absorber through the PCB welding point; and when a street lamp power source is tested in a customhouse, a lot of unnecessary troubles can be eliminated.
Description
Technical field
The present invention relates to a kind of voltage-withstand test earth lead device of built-in anti-lightning strike device 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 when thunder and lightning hits road lamp power supply, instant high-voltage can be sponged by anti-lightning absorber, guarantees the safety of LED street lamp.
The security performance of road lamp power supply, except anti-lightning test, also has the dielectric strength experiment of the 2U+1000V of safe pattern.The road lamp power supply of existing built-in anti-lightning strike device, anti-lightning strike device earth point by the copper nut in shell directly and shell assembly connection carry out ground connection.
When carrying out dielectric strength actual measurement examination, 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 built-in anti-lightning absorber and a road lamp power supply not with built-in anti-lightning absorber respectively, when carrying out anti-lightning test and other tests, using the road lamp power supply of band anti-lightning absorber, 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 voltage-withstand test earth lead device that a kind of built-in anti-lightning strike device 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 test and other a series of test, improve the versatility of test model.
The present invention takes following technical scheme:
A kind of voltage-withstand test earth lead device of built-in anti-lightning strike device road lamp power supply, described road lamp power supply has closed metal shell, case nose face is provided with the hole passed for wire, the circuit board external connection pad short circuit of the anti-lightning absorber of described wire and road lamp power supply inside; Described wire 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 being connected with case nose face by locking device, making anti-lightning absorber ground connection; When carrying out the dielectric strength experiment of 2U+1000V of safe pattern, described wire is separated with case nose face.
Further, the front end face of described shell is detachable end face.
Further, described locking device is bolt nut structure, and the front end of described wire 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.
Further, described circuit board external connection pad is tin welding spot.
Beneficial effect of the present invention is:
1) style need only be provided during road lamp power supply censorship test.
2) censorship style versatility improves greatly.
3) testing efficiency increases.
4) pcb board arranges pad, be connected with wire by pad soldering, thus realize the good short circuit of wire and anti-lightning absorber.
5) locking device locking and fractionation regulate very convenient, improve the convenience of tester.
6) design concept is ingenious, easy to make.
7) drop into little, obviously do not increase cost.
8) especially much unnecessary trouble is eliminated when customs's censorship inspection.
