Correct detection of the electric control system of the suspended platform accessories
Dec 07, 2018

The inspection of the electrical control system of the suspended platform accessories is very important. We can find out the actual state of the system. The insulation resistance between the live parts and the body should not be less than 2 ohms. At the same time, the electrical system of the suspended platform accessories must be set to overheatshort circuit, leakage protection device.

 

The electric control box button of the suspended platform accessories is reliable and the marking is clear and accurate; the system should adopt three-phase five-wire system. The grounding wire and the neutral line should always be separated, and the grounding wire should be yellow-green phased line. The electrical system should be grounded reliably, the grounding resistance should not be greater than 4 ohms, and there should be a grounding mark at the grounding device. The parts of the electrical control system shall be waterproof, shockproof and dustproof; the components shall be arranged neatly, the connection is firm, and the insulation is reliable.

 

The push button switch for the suspended platform accessories control should be accurate and reliable. The exposed part is made of insulating material and should withstand 50HZ sinusoidal waveform. The voltage of 1250V is 1 minute withstand voltage test. An emergency stop button for cutting off the power control loop in an emergency state must be provided on the suspension platform, and the circuit is independent of the control circuit. The emergency stop button is red and has an obvious emergency stopmark that cannot be automatically reset. www.hjplatform.com
