Description

Power on restart device

The power-on-restart device is designed to provide a restarting device that can be easily installed anywhere, used in a motor distribution box, and provides an external direct operation to restart the power distribution box for power transmission and distribution. A trigger unit and an electromagnetic detent unit are used. It has a flexible electrical wire connection that provides large curvature deformation and bending, so that it can be installed at will, and can be remotely operated to restart the utility of power transmission and distribution in the distribution box.

The reason for the power overload is that when the transmitted power exceeds the ampere capacity load of the wire itself, the surface of the wire will generate resistance, which will increase the load on the power supply, and cause ignition due to the thermal resistance effect, or the power output by the motor device at the application end. When encountering mechanical sudden loads such as motors, it will cause power surge loads, especially high-energy-consuming electrical appliances such as induction cookers, electric heaters, etc., which will cause the danger of short circuit of wires. There is a protection switch for maintenance. When there is a sudden power load, the protection switch will cut off the power supply, and then restart the conduction button to continue the power supply.

Relevant power outages are common in homes and factories, especially in workplaces with high energy consumption and frequent sudden loads. The operation and maintenance requirements of the power protection switch inside the distribution box are higher. The unit signs and approves, and after signing, it is sealed with a seal, such as a common lead seal, to prevent the distribution box from being opened at will to modify the circuit, and for the sake of security, the supervisory unit will conduct regular security inspections, including checking whether the power protection switch is working properly. , you need to remove the lead seal marked with Open the box door of the box to restart the power, and then use the lead seal to seal the label, which will cause the process burden of the security inspection operation, and the load within the instantaneous safety value of the machinery and equipment on site. After the protection switch is powered off, the power is restarted. It is necessary to request the competent unit or qualified personnel to participate in the power restart or maintenance start.

Since the above-mentioned maintenance and restart actions for the switch all need to open the box door, which results in a burden on the process, so there is a concept of remote operation to facilitate the maintenance and restart of the power. A flexible actuator is used, and a flexible conductive wire that moves with a metal wire is used to connect to the back of the motor switch. The conductive wire has a slidable core wire inside, and the outer surface is a sleeve.

The routing lines greatly traverse the inner space of the box, and if the curvature of the distribution or the curvature of the corners is too large, it will be caused by the two Different curvatures and mechanical tangential friction cause the inner core wire to rub against the inner surface of the casing, forming friction damping and losing the sensitivity of the contact pressure action.

The switch that is nearby is integrated in the inside of the box The electromagnetic actuating unit at the first part of the assembly adopts a set of electrical wires with a large curvature that can be bent and can be freely routed in any corner of the three-dimensional space inside the box to avoid space occupation. The trigger unit has always borrowed power from external sources such as switches. The input end of the assembly always outputs work commands to the electromagnetic switch unit, so that the electromagnetic switch unit generates instantaneous reciprocating power, and the main purpose is to restart the power of the remote operation switch assembly.

Another aspect of the present invention is that the electromagnetic actuating unit can be combined with the mounting bottom plate of the box body through the assistance of an auxiliary frame to provide a working end for operation, which is coaxially aligned with the restart button of the switch assembly.

The third object of the present invention is that the working end of the electromagnetic actuating unit is provided with a modulating joint, and a protruding cantilever is laterally combined. Press the restart button and stick out the cantilever to adjust the plane angle of the contact pressure shoe.
