Hot-plug type digital power distribution terminal

Abstract

The invention provides a hot-plug type digital power distribution terminal, and the terminal comprises a power distribution terminal main body and a base; the power distribution terminal main body comprises a main control module, and the main control module comprises an operational amplifier unit, a CPU unit, a communication unit, a power supply unit and a first connector; the base comprises a base module; the base module comprises a second connector, a voltage sampling circuit, a current sampling circuit and a terminal; the first connector on the power distribution terminal main body is connected with the second connector on the base, and the strong and weak electricity of the base module is separately designed, so that the hot plug of the digital power distribution terminal is realized;the digital power distribution terminal main body is convenient to install and maintain; when the power distribution terminal breaks down, the power distribution terminal can be directly replaced, a drawer switch main loop of a power distribution cabinet does not need to be powered off, thereby reducing the maintenance cost, reducing the loosening and falling probability of other connecting terminals in the switch unit, preventing operators from electric shock, and improving the working efficiency.

Description

technical field [0001] The invention belongs to the technical field of high and low voltage power distribution equipment, and in particular relates to a hot-swappable digital power distribution terminal. Background technique [0002] At present, digital power distribution terminals are installed on some power distribution cabinets or distribution box panels and drawer switch unit panels in power distribution cabinets, which can comprehensively monitor the residual current, voltage, Electric parameters such as current and electric energy and temperature are monitored and indicated, and it plays the role of human-computer interaction. At present, digital power distribution terminals are developing in the direction of digitalization, integration, intelligence, and lightweight. The existing digital power distribution terminals have complex installation structures in power distribution systems and poor maintainability.

Problems solved by technology

At present, digital power distribution terminals are developing in the direction of digitalization, integration, intelligence, and lightweight. The existing digital power distribution terminals have complex installation structures in power distribution systems and poor maintainability. They need to be disconnected before installation and disassembly. Only when the front panel of the switch unit of the power distribution cabinet is turned on and opened, can the connection wires of the digital power distribution terminal be connected and pulled out. Such an operation method is not convenient for operators to install and replace on site, and it is easy to cause loosening of other connection terminals inside the switch unit. , falling off, causing the power distribution cabinet to work abnormally, and the switch unit is turned on at the same time for operation, and the operator is in danger of electric shock

[0003] The hot-swappable digital power distribution terminal disclosed in the Chinese Patent Application Publication (Application Nos. 201910382226.5, 201910382227.X, 201920655451.7, 201920655095.9) proposes a design idea of ​​a hot-swappable digital power distribution terminal, which solves the problem to a certain extent The existing digital power distribution terminal is inconvenient to maintain, but there is still a certain risk of hot-swapping safety. When the power distribution cabinet or distribution box is charged, the digital power distribution terminal is plugged and unplugged, and the connection terminal interface involves strong current. The problem of plugging and unplugging, the division of strong and weak currents is not complete, and the safety is not high enough, which may easily cause digital power distribution terminals to burn out
