电路检测（Circuit detection）.doc

电路检测（Circuit detection） 1. view, test Check whether the original circuit has leakage protector, if any, press the test button in the energized state, check whether the leakage protector is reliable, and test other air switches to see whether it is flexible and normal. 2. shake Take the master switch, shake the meter, measure the resistance of each line to the ground, and see the insulation resistance between the line and the line to see whether it is normal. Make sure the inspection is normal and fit in the case cover. 3 、 weak current testing Detect television lines, telephone lines, network lines, etc.. 4, the original room switch, socket testing 4.1 on the lighting circuit power, according to each room switch to see whether they are lit. If the distribution box has two or more than two lighting circuits, then determine each circuit clearly corresponding line. 4.2 remove the switch panel to see the size of the wire and whether the wires are separated. 4.3, check each socket whether power, wire diameter, wire color separation, single-phase socket is left, zero, right, fire grounding, three-phase socket is three phase one ground (zero). 5, provide relevant information Require owners to provide the original strong and weak layout drawings, related circuits, electrical drawings and data, and ask whether the owners have purchased sufficient construction temporary electricity. 6 、 test relevant standards and requirements 6.1 wire and wire to ground resistance must be greater than 0.5M ohm. 6.2 of the original real wire diameter should meet the following requirements: lighting circuit with copper wire is over 1.5mm2, using socket loop of copper wire was 2.5mm2, copper wire was 4mm2 with air conditioning circuit. The 6.3 level should be between 6080dB cable. 6.4, if the measured data does not meet the relevant standards and requirements, we must inform the owners, requiring property rectification, when the inspection fully meet the requirements before construction.
