High speed high lamp electrical part of what?

High speed high lamp electrical part of what? 1. Power supply: 50 hz, ac three-phase five wire, 380 v / 220 v; 2. High lamp power distribution control box should be 3 with overload, short circuit and earth leakage protection device. Circuit breakers, leakage protector, contactor, circuit breaker, contactor must



high speed high lamp 【 Light, generally refers to more than 15 meters steel conical light pole and high-power modular fixtures are composed of new type of lighting. 】 What are the composition of electrical parts? 1. Power supply: 50 hz ac three-phase five wire' Three-phase five wire system including three phase line (three-phase electric A, B, C) , neutral line ( N line) ； And the ground ( PE line) 。 】 380 v / 220 v; 2. Light distribution control box 【 The control box is used widely. 】 Should have overload, short circuit and earth leakage protection device' Leakage protection devices are used to avoid personal electric shock and leakage accident caused by a ground fault protection, when the circuit or the set values for the leakage current is greater than the device's electrical equipment, or people and animals get an electric shock risk occurs, it can quickly action, to cut off the power supply, avoid the expanding of the accident, to ensure the safety of person and equipment. 】 3. Circuit breakers, leakage protector' Leakage protector, referred to as 'leakage switch, also called leakage circuit breakers, leakage is mainly used in equipment failure, and to a potentially lethal person get an electric shock protection, overload and short circuit protection function, can be used to protect lines or motor overload and short circuit, can be in normal circumstances for the use of line not frequent conversion start. 】 , contactor, circuit breaker, contactor must with auxiliary contact, and the auxiliary contact must lead to the terminal; 4. Growing within the various power supply cable should pass special fixture and reliable connection, wire rope with wire rope hoist, itself does not bear weight. Illumination power supply cable for YC 【 YC（ Yang, c + +, YC) Browsers - — At first a new browser kernel, YC browser kernel ( Temporarily named Ycweb) Research and development began at the end of 2001, lasted ten years. 】 High quality heavy cabtyre cable' Heavy cabtyre cable can bear larger external mechanical forces, apply to the rated voltage is 0. 66/1. 14 kv and below power transmission of underground mobile equipment. 】 ; 5. Lamps and lanterns and light source USES imported or domestic high pressure sodium lamp, wall lamp, of course, the conditional user can also choose to energy-saving led project-light lamp very much
