Problems solved by technology

In the non-stop operation, the 400-volt non-stop operation using the bypass operation method occupies a considerable proportion. The operators usually use the ordinary low-voltage air switch as the bypass switch, which cannot monitor the bypass current and voltage in real time, and cannot The phase sequence on both sides of the switch is quickly checked, and the work preparation time is longer
Since the workers directly operate the opening and closing of the bypass switch, when the bypass switch insulation or mechanical failure occurs, it is easy to cause injury to the workers

Abstract

The invention discloses a 400V multifunctional bypass switch cabinet, which is characterized in that a voltmeter is installed on an upper panel, a voltage value can be read from the front of a mechanical instrument, a wiring terminal is arranged on the back of the mechanical instrument, and the mechanical instrument can measure the three-phase voltage conditions at the two ends of a load switch; athree-phase ampere meter is installed on the upper panel; a phasing tester is installed on the upper panel; a phasing indicator lamp is installed on the upper panel; a multifunctional metering display meter is installed on a lower panel; and real-time and historical power and electric quantity of a bypass can be checked on the front. According to the using method of the 400V multifunctional bypass switch cabinet, one end of a low-voltage flexible cable is inserted into a corresponding wire outlet end cable quick plugging interface of the device, and after the phase sequence is all correct, anoperator rotates a switch operating handle in the device from a switching-off position to a switching-on position. The 400V multifunctional bypass switch cabinet has the advantages that the operatoris isolated from an electrical loop, the personal safety is guaranteed, the bypass phase sequence is conveniently and quickly checked and adjusted, the triple phase sequence checking and protecting functions are achieved, and the operation efficiency and safety are improved.

Description

technical field [0001] The invention relates to the technical field of electric power construction auxiliary tools, in particular to a 400-volt multifunctional bypass switchgear and a use method thereof. Background technique [0002] With the rapid economic and social development, power users have higher and higher requirements for power supply reliability, and non-stop operation is one of the important measures to improve power supply reliability. In the non-stop operation, the 400-volt non-stop operation using the bypass operation method occupies a considerable proportion. The operators usually use the ordinary low-voltage air switch as the bypass switch, which cannot monitor the bypass current and voltage in real time, and cannot The phase sequence on both sides of the switch is quickly checked, and the work preparation time is longer. Since the operator directly operates the opening and closing of the bypass switch, when the bypass switch insulation or mechanical failur...
