The invention provides a new main shaft condensate water and external water cooling water protection method, and belongs to the technical field of frequency converter protection. Comprising the following specific steps: step 1, mounting humidity probes: mounting a plurality of humidity probes at a cooling water pipe part of a frequency converter of a main well; 2, humidity is monitored, an operation platform of a control room is electrically connected with a plurality of humidity probes through wires, uninterrupted monitoring is carried out within 24 hours, after the humidity probes detect humidity signals, audible and visual alarm signals are immediately output to the operation platform, and a driver is reminded that condensate water is generated in the frequency converter, and the frequency converter needs to be stopped for inspection immediately; and 3, water level probes are installed, a plurality of water level probes are installed in an external water cooling water supplementing water tank communicated with a cooling water pipe of the frequency converter, after water shortage protection is added, an alarm is given to supplement water in advance after the water level drops to a set value, the influence of main shaft coal lifting is reduced, the water supplementing efficiency is improved, and the time needed by water supplementing is shortened.
Description
technical field [0001] The application relates to the technical field of frequency converter protection, and in particular, relates to a method for protecting condensed water of a new main well and cooling water of external water. Background technique [0002] The vertical shaft and inclined shaft that are responsible for the main task of lifting ore in the mine (pit mouth) are called the main shaft. The main shaft is a well shaft specially used for lifting coal. In large and medium-sized mines, skips are often used for lifting coal containers, so the main shaft is often called a skip well. In the Sichuan area, the flat alley is used as a transportation alley, also known as the main well. [0003] There are two potential safety hazards in the existing coal mine main shaft hoisting electric control: 1. The frequency converter is prone to condensate water when the air conditioner cannot operate normally and the air is humid in summer, causing damage to the control board of th...
