1-20KVA power special UPS host module of 3U standard case

Abstract

The invention discloses a 1-20 KVA power special UPS host module of a 3U standard case, which comprises a case body, wherein the case body is internally provided with a USP host module, the USP host module comprises a switching unit, a resistor, a rectifying unit and bus capacitors, the switching unit is located on the left side of the rear part in the case body, the resistor is arranged on the right side of the switching unit, the rectifying unit is mounted on the right side of the resistor, a plurality of bus capacitors are arranged on the front side of the switching unit, inversion units are embedded in the two sides of each bus capacitor, a DSP control unit is arranged on the right sides of the inversion units, and a filter capacitor is arranged on the front side of the DSP control unit. The UPS power supply of the 1-20KVA power section is creatively compressed and designed in the 3U case, so that the equipment size is reduced, the transportation, installation and after-sales maintenance and replacement of the equipment are facilitated, and the production cost and the customer use cost are reduced; due to the design that the bus capacitors and the inverter circuit are mounted in an embedded mode, the distance between the bus capacitors and the inverter circuit is greatly shortened, electromagnetic interference caused by line parasitic inductance is reduced, and the system operation is more stable.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to a 1-20KVA power dedicated UPS host module with a 3U standard chassis. Background technique [0002] The special UPS power supply for electric power is mainly designed and manufactured according to the characteristics and requirements of the power system. It is suitable for the high-quality and high-reliability requirements of the power supply equipment in the power system. It is mainly used in places where the load requires high voltage reliability, such as power telecontrol, RTU , power carrier, monitoring, etc. It can meet the power demand of terminal equipment such as computers in the power control system, and can bring the best guarantee for the safe and reliable operation of the power control system.

Problems solved by technology

[0003] At present, there are many sizes and appearances of UPS dedicated to power in the 1-20KVA power range, and the power range covered by a UPS of one specification is basically very narrow, which is inconvenient for the production and use of the equipment, and the structure is complicated and cannot be standardized. The distance between devices is long and the connection is long, so the failure rate is high and it is easy to be interfered

The production process is complicated, the efficiency is low, the after-sales maintenance is difficult, and the maintenance cost is high
