Fuse holder and fuse are a kind of product that we often contact at ordinary times, almost every family is equipped with such a kind of protection measures to protect our safety;

This article will introduce some detection methods of fuse holder. I believe that you will have a more comprehensive understanding of fuse holder through today’s introduction.

What are some testing methods for fuse holder?

Before introducing these testing methods, we should first know and clearly understand some evaluation criteria of these testing methods, so as to better help us to compare and clearly understand how to evaluate the quality of such a fuse holder during or after testing.

Some evaluation criteria of fuse holder detection method:

(1) according to the rated current on for an hour, the fuse will not fuse.

(2) according to the rated current when the power, the fuse seat temperature rise is less than 75 degrees

(3)The fuse will blow in one minute when it is charged with twice the rated current

(4) in addition to the rated short-circuit capacity, the occurrence of continuous arc and ignition

We will carry out the detection according to the above standards. Next, we will introduce some fuse holder detection methods:

Temperature and voltage detection:

Make use of the power supply to put current and voltage on the fuse block, keep the voltage at 220V, and the current starts from 2A, increase the current 2A-10A after 4-5 minutes, the temperature rise is less than 75 degrees when the rated current is switched on.

Circuit breaker time test:

The stopwatch is used to record and observe the time required for the fuse to fuse when the fuse holder is given twice the rated current and the current is turned on. The fuse needs to fuse within one minute when the fuse is passed twice the rated current, and photos before and after the fuse is taken

Fuse sample test:

Provide three fuses of the same specification, each providing twice the rated current and other current flow to calculate the average fusing time.

In this way, we have completed the test of a fuse holder. According to the comparison between the experimental results and the expected results, we can get the result whether the fuse holder has passed the test and whether it meets the standard.Hope you like it!HINEW fuse block factory specializes in:inline fuseholder,panel mount fuse holder,PCB fuse holder,automotive fuse holder;Welcome to consult ~
