Abstract

The invention discloses a power system for a sewage processing device. The power system comprises a photovoltaic power supply apparatus, a commercial power supply apparatus, a power conversion apparatus, a control module and a blower fan, which are connected through shielded cables, wherein the photovoltaic power supply apparatus and the commercial power supply apparatus are jointly connected to the power conversion apparatus to select corresponding power supply means, and the control module drives the blower fan to rotate when the power conversion apparatus outputs currents. The two ends of the control module respectively access to a first grounding element and a second grounding element, wherein the first grounding element is connected between the input end and the grounding end of the control module, and the second grounding element is connected between the output end and the grounding end of the control module. The power system is improved at least in one aspect among energy saving and environmental protection performance, safety, interference immunity or controllability, low noise and high efficiency.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to the power system of sewage treatment equipment and its sub-systems or components. Background technique [0002] In the power system of sewage treatment equipment, the fan as the load equipment is connected to the power conversion device of the power supply end through the control module. Device control. [0003] There are deficiencies in the design of the above-mentioned power system: 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 great impact on the stable operation of the load equipment; the control is not enough Convenience, can not meet the needs of users; the fan vibration noise is large, the efficiency is not high; and so on. In view of this, it is necessary to involve new sewage treatment ...
