The application of Bronze terminal in electric construction organization design :

According to the construction equipment load and power distribution control arrangement of partial power supply wire section, arranged as follows: the choice of electrical distribution box electrical installation wire section selection. Total electrical box with60cm ×80cm ×20cm iron electric box, according to the total load calculation of power 22lead-in wires using RVV3× 16 M× 10 +2M rubber multi-strand cables with copper core wire. Be buried at a depth of 0.6M, using HR5-100/31fuse body power isolation switch, PZ20Y-100/3300 automatic circuit breaker switch, DZ15LE-100/4901leakage circuit breaker, leakage action current not less than 50mA, time0.1S, working zero line, protective zero line is arranged in the box body are respectively provided the selection of bronze terminals, repeat earthing and protective zero line connected with the construction of the electric box, a metal shell are connected to form a protection net, and ground protection, prevent the electric shock accident.

Electric safety technology measures

1, strict implementation of national construction ministry construction of GB3806-83 and JGJ46-88electrical safety standard, elaborate organization construction electricity design installation maintenance work, good safety electricity operation records.

2, performing five wire electricity requirement, ensure" a machine, a gate, a drain" purchase qualified electrical accessories, according to the equipment load situation, correct choice of preventing overload, under-voltage, edge flow, leakage of safety interlocking protection device.

3, do the box and the box, box and the machine meets zero protection, grounding repeatedly, ground protection measures. Often the test of grounding resistance, good resistance variation recording.

4, strictly implement the operation of induction system, strengthen the equipment operator electrical safety education, discover hidden timely notify the professional electrical repair check, put an end to stop the operation of equipment.

5, in strict accordance with the standard requirements for installation of lines and electrical equipment, waterproof, moisture-proof, naked, to prevent accidents, improve the electric circuit device shielding protection.

In 6, seriously implement the regional power supply plan, to different area, different locations of correct selection of power supply mode on the dangerous position, using safety voltage supply, ensure the equipment safety.

7, do a good job of mine, anti-static technology management, do well the gap shielding lightning protection device technical measures.
