Embodiment Construction

[0045] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with the embodiments and accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0046] In order to solve the problems of large size and high price of the existing DC mechanical switch with arc extinguishing device, and the problem of excessive current caused by the load being energized instantaneously when DC power is applied, a proposal is proposed in this example A line switch control system to reduce the current pulse generated at the load end when the DC is powered on, avoiding damage to the load and switching devices, and reducing the possibility of danger.

[0047] Specifically, in this example, the soft-start switch is realized by using the monitoring equipment, the...

Abstract

The invention provides a line switch control system, method and device. The control system comprises monitoring equipment, a master control chip, a drive chip and a controller, wherein the monitoringequipment is used for collecting line information of a controlled circuit; the master control chip is connected with the monitoring equipment and is used for receiving the line information, collectedby the monitoring equipment, of the controlled circuit and generating a control signal according to the line information; the drive chip is connected with the master control chip and is used for the control and carrying out drive control on the controller according to the control signal; and the controller is connected with the drive chip and is used for carrying out switch control on the controlled circuit under the drive control of the drive chip. Through the line switch control system, method and device, the technical problems that an existing mechanical DC switch is short in life, overlarge in volume and relatively high in cost are solved, and the technical effects of effectively reducing the volume of the switch and reducing the cost are achieved.

Description

technical field [0001] The invention relates to the technical field of circuit control, in particular to a circuit switch control system, method and device. Background technique [0002] With the development of new energy, the application of direct current has been driven, and more direct current appliances have been used by people. In the Energy Internet system, the safety of DC appliances is very important, including reliable switching of the power supply. The current DC switch is generally equipped with a DC contactor. This kind of mechanical switch has a large volume and high cost due to the internal arc extinguishing device, and it is not convenient to use in the environment of low-power electrical equipment. [0003] For the above problems, no effective solution has been proposed yet. Contents of the invention [0004] The embodiments of the present invention provide a line switch control system, method and device, which solve the technical problems of excessive vo...
