Abstract

The invention discloses a shielded cable connection structure 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 fan. The characteristics lie in that the photovoltaic power supply device, the commercial power supply device, the power supply conversion device, the control module and the fan in the shielded cable connection structure are connected through shielded cables, and a shielding layer of the shielded cable between the power supply conversion device and the control module and a shielding layer of the shielded cable between the control module and the fan are grounded. The shielded cable connection structure disclosed by the invention at least can improve the performance of the power system at a certain aspect of energy conservation, environment protection, safety, anti-interference performance or controllability, low noise, high efficiency and the like.

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 ...
