Power distribution unit

Abstract

The invention discloses a power distribution unit. The power distribution unit comprises a housing, a power supply line, a plug and a plurality of socket units, the socket units are arranged side by side and arranged in the housing, one end of the internal portion of the housing is an electric control region, the electric control region is provided with a power source switch configured to cut offor connect with the power supply line, the power supply enters the housing from the end portion of the housing, penetrates the electric control region and connects with the socket unit, wherein the electric control region is internally provided with a first isolation part, a second isolation part, a third isolation part, and a first circuit board and a second circuit board, the first isolation part, the second isolation part and the third isolation part are arranged at intervals from bottom to top; the first circuit board is arranged between the first isolation part and the second isolation part; and the second circuit board and the first coil are arranged between the second isolation part and the third isolation part. The power distribution unit has the arc detection, anti-thunder and alarm function, and cannot increase the volume of the power distribution unit.

Description

technical field [0001] The invention relates to a power distribution device, in particular to a power distribution unit with functions such as arc detection, lightning protection, and alarm. Background technique [0002] The Power Distribution Unit ("PDU") is a commonly used power distribution socket in the communication room, which is used to distribute power to the electrical equipment in the cabinet. With the popularization of smart appliances, more and more enterprises and institutions And public places where people gather have their own communication room, so the application of power distribution unit is more and more extensive. [0003] With the continuous development of science and technology, there are more and more communication devices such as servers and switches, and the diversity of loads has higher and higher requirements for power distribution units. Long-term overload work is also huge for power distribution units. At present, due to problems such as arc and...

Problems solved by technology

[0003] With the continuous development of science and technology, there are more and more communication devices such as servers and switches, and the diversity of loads has higher and higher requirements for power distribution units. Long-term overload work is also huge for power distribution units. At present, due to problems such as arc and lightning, damage to electrical equipment, paralysis of power supply systems, and even fires are common. Most of the existing related products adopt arc-proof structures instead of arc detection, such as: public The patent document CN208111738U discloses an arc-proof smart socket. In the disclosed socket structure, the creepage distance is increased by adding a winding mechanism. If an arc occurs, the insulating ring can increase safety. Obviously , this structure prevents the arc from hurting people by adding an isolation layer outside the jack, but it cannot detect the existence of the arc, and it is difficult to avoid the damage of the arc to the equipment itself; another example: the patent document with the publication number CN2717068Y discloses a The rotary plug of the suppression mechanism suppresses the occurrence of sparks by setting the plug in a rotary structure. This structure can reduce the occurrence of arcs to a certain extent, but it cannot continue to suppress sparks after it is connected to power-consuming equipment, and there is no Arc detection function

Moreover, the arc-proof smart socket and the rotary plug disclosed in the above-mentioned patent are all single-hole plugs, which cannot be used in communication equipment rooms.

[0004] In addition, due to the dense power-consuming equipment and little free space in the communication room, customers generally tend to buy power distribution units with many jacks and small size. Adding functions such as arc detection, lightning protection, and alarm will inevitably lead to a large increase in the size of the power distribution unit. Increasing or reducing the number of sockets will reduce product competitiveness; at the same time, after adding functions such as arc detection, lightning protection, and alarm, due to the increase in contacts on the circuit board in the power distribution unit, and the shell of the power distribution unit is mostly a metal shell, In order to prevent the air from being broken down, a safe distance must be kept between the circuit board and the strong current line, and between the strong current line and the metal shell. After adding functions such as arc detection, lightning protection, and alarm, it is difficult to achieve power distribution unit The overall volume remains unchanged, therefore, it is very difficult to take into account the safety, volume and function of the power distribution unit at the same time under the current technical level
