Wire connector fitting detector heat detector detection jierongfa Jie Rong hair

 Check wire connector fitting detector heat detector detection operation of electrical equipment joint, demand a temperature of not more than 70 ℃. When the joint temperature reached or exceed 70 ℃ must be processed. View popular way to send a lot of, here are some common ways to view the contact heat. 1, wire connector fitting detector heat detector smell detection method. Nostrils smell detection wire connector adjacent coke burnt smell is not there, but the most simple way. If you recognize the coke burnt taste from wire connectors, then the joint temperature must at least 70 ℃. 2, wire connectors detector joint detector test method candle heat detection methods. Candles tied insulated rod end head touch test contacts, such as the slow melting temperature is about 55 ℃; as soon melt flow, temperature above about 70 ℃; such as fast melt and run fumes, temperatures above about 200 ℃. 3, wire connectors joints detector heat detector detection survey. (1) If the wire connector outsourcing insulating tape yellow, black, its temperature will be above the joint 70 ℃. (2) the rain to see the contact method: Rainy Day look boring junction temperatures above about 50 ℃; raindrop immediately transpiration gasification temperatures above about 100 ℃; as announced "laugh!" Voice, big raindrops were rolled into shape , at a temperature of about more than 200 ℃. Rainy Day View contacts fever, easy to find, and high efficiency. (3) the snow to see the snow melting process: see the snow melting on the contact temperature above about 0 ℃; such as contacts dry, temperatures above about 50 ℃. (4) to investigate the hot air law: the heating element and the air temperature up to 20 ℃ or so, that could see a small stream; such as when the joint temperature reaches 100 ℃, "hot air" is very significant; such as joint temperature reaches above 200 ℃ , "hot air" is very simple to be seen; if the joint is a combination of several contacts made, see "hot air" can also tell which contacts the heat. To clearly see the "hot air" exists, it is necessary to aid airflow behind the "set" to investigate. It was selected "set" Demand is black, gray and other dark, lines, net and so can. Wires and equipment so you can do "scenery." When viewing a contacts view to changing personnel standing position, shape and angle of the contacts together as much as possible, was parallel to the situation, so that the top of the contact and then slowly approaching "set", leaving only a small crevice is not shaking. If shaking, indicating that the contact heat; Swaying, a serious fever. 4, wire connectors detector heat detector joint detection method with the thermometer. Infrared thermometer is the leading instrument, use the more convenient, regularly check the effect of outstanding contacts.
