Storage cell of sewage treatment equipment power system

Abstract

The invention discloses a storage cell of a sewage treatment equipment power system. The sewage treatment equipment power system comprises a photovoltaic power supply device, a commercial power supply device, a power supply conversion device, a control module and a blower. The photovoltaic power supply device comprises a photovoltaic cell, a photovoltaic controller, the storage cell and an inverter circuit. The photovoltaic controller is provided with a charging circuit, a discharging circuit and a control circuit. The charging circuit is connected between the photovoltaic cell and the storage cell. The discharging circuit is connected between the storage cell and the inverter circuit. The control circuit is respectively connected with the charging circuit, the discharging circuit and the storage cell. The inverter circuit is connected with the power supply conversion device. The storage cell comprises a storage cell body, a cell management module, a data bus, an auxiliary power supply bus and an auxiliary charging control line. The positive electrode and the negative electrode of the storage cell body are respectively connected with the cell management module. Performance of the power system can be improved in a certain aspect among energy conservation and environmental protection, safety, anti-interference performance or controllability and low noise and high efficiency.

Description

Technical field [0001] The invention relates to sewage treatment equipment, in particular to the power system of the sewage treatment equipment and its sub-systems or components. Background technique [0002] In the power system of the sewage treatment equipment, the fan as the load equipment is connected to the power supply conversion device of the power supply terminal through the control module. The control module converts the AC power output by the power supply terminal into the AC or DC power required by the load equipment, thereby achieving the load Control of equipment. [0003] The above-mentioned power system design has shortcomings: the use of a single mains power supply is not environmentally friendly and energy-saving; the lightning protection measures are not good enough, and the system security is poor; the anti-interference measures are not ideal, which has a greater impact on the stable operation of the load equipment; Convenient, can not meet the needs of users we...
