Problems solved by technology
At present, most of the test devices for DC power distribution products are distributed. During the test, multiple people are often required to check each meter at the same time. The wiring on the test site is relatively confusing. There are potential safety hazards during the power-on test, and the test efficiency is low. Generally, connection tests are required during operation. load, and sometimes use electric stoves, electric kettles, etc. as loads during testing, which is neither standardized nor safe

Embodiment 2
[0016] Such as figure 2 Shown is Embodiment 2 of the present invention, including a test device and a tested 240V DC power distribution product. The test device includes components such as a voltage output module, a current output module, and an electric meter indicating unit. The voltage output module includes a 220V AC to 240V DC AC-DC converter (model S-360-240), a 220V input socket, and a pair of 240V output terminals. The 240V DC power supply output is used to provide the working voltage for the DC power distribution product under test. The current output module includes one 220V AC to 12V DC AC-DC isolation converter (model S-120-12), one adjustable constant current source (model SH-PWS2(8A)), one 220V input socket, 1 pair of constant current source output and input binding posts. The isolated 12V DC is used to power the constant current source. The constant current source module includes one (or multiple) 8A constant current source modules, and the output size of t...

The present invention provides a direct current distribution product test method. The invention aims to eliminate defects in the prior art. With the direct current distribution product test method adopted, various main test functions can be effectively integrated, simplicity and convenience can be brought about, test efficiency can be greatly improved, and the standardization of test operation canbe improved. An entire test process does not require a tested direct current distribution product to carry a load, therefore, the method is safe and can save power, and test devices can be small in size. According to the test principles of the method of the invention, the tested direct current distribution product is generally a 48V or 240V direct current distribution product, such as a power distribution screen and an array cabinet; such kind of direct current distribution product is generally equipped with a direct current voltmeter and a direct current amperemeter; and when working voltageand working current are applied to the direct current distribution product, if the indications of the voltmeter and amperemeter of the tested direct current distribution product are normal, it is indicated that the circuits such as the input and output channel circuits and voltage and current detection circuits of the direct current distribution product work normally, and therefore, the tested direct current distribution product can be tested.
Description
technical field [0001] The invention relates to a test method for communication power distribution products, in particular to a production test method for DC power distribution products with convenient operation, standardization, safety and energy saving, specifically a test method for DC power distribution products. Background technique [0002] Communication power distribution products generally use DC power supply and distribution, mainly including -48V and 240V DC power distribution products, such as power distribution panels, column cabinets, etc. At present, most of the test devices for DC power distribution products are distributed. During the test, multiple people are often required to check each meter at the same time. The wiring on the test site is relatively confusing. There are potential safety hazards during the power-on test, and the test efficiency is low. Generally, connection tests are required during operation. The load, even sometimes using electric stoves...
