9 Electrical safety elevator safety device for an elevator specialized electrical equipment and wiring security measures must be taken to lift the host, to prevent electric shock and equipment damage accidents. According to the requirements of GB 7588-1995, the elevator should take the following electrical safety protection measures. (1) direct electric shock protection. Insulation is the basic measure to prevent direct electric shock and electrical short circuit occurs. (2) Indirect electric shock protection. Indirect contact refers to the shock normal human contact is not energized and energized electrical equipment failure exposed conductive parts, such as metal, metal conduit, trunking and other occurrence. In power neutral directly grounded power supply system, to prevent indirect contact is the most commonly used protective measures will likely live electrical equipment failure the exposed conductive parts of the neutral point of the transformer and power supply are electrically connected. Elevator installation quality verification common question 2, the elevator test GB10060-93 4.6.7 provides a test lift elevator provisions: a car-load, respectively, 50% of the rated load and rated load three conditions community Elevator, and in the case of continuous power rate of 40%, to reach the full travel range of the elevator system, at 120 times / h, not less than 8h per day, each starting and braking run 1000 times, the elevator should run smoothly, brake can be *, continuous trouble-free operation. But in the field of quality verification and verification of information often found the following problems. 2.1 test conditions do not meet the regulatory requirements for elevator test shall be under three working conditions separately. Where no-load and full-load operation test run test is the test specification under two kinds of important working conditions. For assessment focuses on the balance of the car and the elevator brake under these two kinds of working conditions is available * elevator leveling accuracy and other properties. Found at the scene often overlooked load and full load conditions demands, or 20%, 80% of the rated load replace, or does not consider the working conditions do not meet the requirements are.
