Embodiment

[0020] As shown in the figure, the present invention includes two parts, the upper and lower parts of the box body and the box cover, and the inside of the box cover mainly places safety tools.

[0021] The box is equipped with a dual power switch 6, a status display light 8 and an alarm buzzer 7. There are two sets of rain-proof power terminals and a set of rain-proof load terminals 3 on the outside of the box. The two sets of power terminals are mainly Power terminal 1 and standby power terminal 2, the two primary input terminals of the dual power transfer switch are connected to the main power terminal 1 and backup power terminal 2 respectively, and the output terminal of the dual power transfer switch is connected to the load terminal 3; The status display lamp 8 and the buzzer 7 are connected to the secondary auxiliary contact of the dual power supply switch through copper-plastic wires.

[0022] The exterior of the dual power transfer switch is sealed with an insulating ...

Abstract

The present invention relates to a movable type low-voltage dual-supply converter. The converter comprises a box body, a dual supply transfer switch, the box body is internally provided with the dual supply transfer switch, a state display lamp and an alarm buzzer. The outer side of the box body is provided with two groups of power supply wiring terminals and one group of load wiring terminal, two primary input terminals are connected with the two groups of power supply wiring terminals, and the output end of the dual supply transfer switch is connected with the load wiring terminal; and the state display lamp and the alarm buzzer are connected with the secondary auxiliary contact of the dual supply transfer switch through a copper-plastic wire. The movable type low-voltage dual-supply converter practically ensures the automatic transition of the dual power supply, shortens the power failure time, obtains great application of each power protection field, is portable and convenient to move, and is not limited by the field environment of the device.

Description

technical field [0001] The invention relates to a dual-power converter, in particular to a mobile low-voltage dual-power converter, which belongs to the field of electric power applications. Background technique [0002] As the requirements for power supply in important power consumption places gradually increase, the power supply company's power maintenance tasks are also increasing, and emergency generator vehicles have become indispensable power protection equipment. When users build new substations, in order to reduce economic costs There is no spare busbar reserved in the cabinet, so that after the emergency generator vehicle of the power supply company arrives at the power protection site, the low-voltage cable can only be placed next to the distribution box, and cannot be connected to the user's load side. If a line failure occurs during the period, the equipment will trip . The power personnel should remove the user's switching power supply side cable, and then conn...
