Water level monitoring device and monitoring system for transformer substation

Abstract

The invention discloses a water level monitoring device and monitoring system for a transformer substation and relates to the technical field of water level monitoring devices. The water level monitoring device comprises an analog quantity input unit, a switch quantity output unit, a central processing unit, a power supply unit, a switch quantity input unit, an address control unit, a wireless signal receiving-emitting unit and an analog quantity output unit. The monitoring device is not only capable of monitoring the water level information in real time to control the running of a water pump but also capable of monitoring the current and voltage of the running water pump in real time to timely discover the abnormal work of the water pump, and the water level monitoring device is featured with safe and reliable use.

Description

technical field [0001] The invention relates to the technical field of water level monitoring devices, in particular to a water level monitoring device for a substation and a monitoring system thereof. Background technique [0002] In power production, the drainage of deep water wells in substations is generally manual drainage at present. Since most of our country is unattended substations at present, the water level of this drainage method has no scientific classification. It takes a long time to prepare, consumes a lot of vehicles and equipment, and other manpower and material resources, causing great safety hazards and hazards to power production. Moreover, the drainage record items are simple and the statistical effect is poor. It is difficult to form a decision-making basis for technological transformation and upgrading of power production. In addition, the current and voltage of the water pump cannot be monitored in time, which has great risks. Contents of the inven...

[0002] In power production, the drainage of deep water wells in substations is generally manual drainage at present. Since most of our country is unattended substations at present, the water level of this drainage method has no scientific classification. Long preparation time, large consumption of vehicles and equipment and other manpower and material resources, great potential safety hazards and great harm to power production, and simple drainage record items, poor statistical effect, it is difficult to form a decision-making basis for power production technology transformation and upgrading

In addition, the current and voltage of the pump cannot be monitored in time, which has a great risk
