Why does the knife switch need temperature measurement

With the increasing demand for power reliability, a certain component in a substation heats up severely and loses its original function, which means it will cause major power outages to users or major equipment damage accidents to the substation. The knife switch components of the substation, due to their rotatability and frequent operation, have always been the most vulnerable components to overheating and damage in the substation. In the safe operation system of power equipment, temperature is an important parameter to verify the normal operation of primary equipment. The connection parts of power equipment, due to changes in climate, equipment foundation, công nghệ xử lý, environmental pollution, severe overload operation, contact oxidation, và những lý do khác, cause loose crimping, insufficient pressure, changes in contact parts, and ultimately increase contact resistance. When current passes through, the temperature rises, causing equipment aging, insulation decline, và trong trường hợp nặng, triggering arc short circuits, burning out equipment, expanding the scope of equipment damage, reducing equipment service life, and even easily causing a fire and explosion of the equipment, especially the dynamic and static contact parts of the movable knife switch, which have a high failure rate, all of which constantly threaten the safe operation of power equipment.

What are the temperature measurement methods for the knife switch

The traditional inspection method uses manual operation or automatic program control of unmanned aerial vehicles with dual light cameras (visible light cameras and thermal infrared cameras) for inspection. Sau đó, visible light photos and infrared photos are exported from the unmanned aerial vehicles. Sau đó, by comparing the visible light photos, the knife switch equipment and contact points on the infrared photos are found and marked. Cuối cùng, the marked infrared photos are read using temperature measurement software to display the temperature of the knife switch contact points. Tuy nhiên, due to the fact that there are at least dozens of infrared photos taken during a single inspection, and each photo contains more than 20 knife switch devices, manually marking the contact points of the knife switch on the infrared photos is very cumbersome and time-consuming. Hơn thế nữa, it is difficult to directly find the knife switch equipment from infrared photos, and it is often necessary to compare visible light photos taken at the same time to determine the position of the knife switch in infrared photos. Manual marking may result in missed or incorrect labeling. Đồng thời, the inspection frequency of substations (at least once a day) is high, and the manual marking work is very time-consuming. There is an urgent need for a more efficient method to replace it.
The traditional temperature measurement methods for substation knife switches include infrared thermal imaging temperature measurement, point infrared temperature measurement, Và đo nhiệt độ không dây. The above temperature measurement methods either have low real-time performance, chi phí cao, or are prone to damage and cannot automatically adjust the temperature. They cannot automatically cut open or close when the temperature of the knife switch suddenly rises.

Knife switch fiber optic temperature measurement device

các hệ thống đo nhiệt độ sợi quang huỳnh quang is a device that controls the high-speed electric telescopic rod to work quickly and cut off when the temperature of the knife switch arm exceeds a certain set value, avoiding damage to electrical equipment caused by high temperature of the knife switch. Quan trọng hơn, due to the large temperature difference between the two sides of the temperature difference generator on the knife switch, the power generation is large, and the fan simultaneously cools down on one side of the temperature difference generator. The temperature difference generator absorbs a large amount of heat. When the temperature of the knife switch arm drops below the set temperature, bộ điều khiển điều khiển cần gạt điện tốc độ cao để đóng nhanh cánh tay công tắc dao, đạt được khả năng điều khiển thông minh và tự động của công tắc dao, tiết kiệm nhân lực và tài nguyên vật chất, và giảm thiệt hại kinh tế; Hiển thị tín hiệu nhiệt độ trực tiếp và điều khiển thiết bị báo động cục bộ gửi thông tin, cung cấp giao diện đầu ra cảnh báo từ xa để kết nối với các hệ thống thông tin khác. Gửi thông tin cảnh báo và dữ liệu đến trung tâm giám sát để theo dõi thời gian thực trạng thái của công tắc trạm biến áp không người lái, sửa chữa kịp thời, và tránh thiệt hại về kinh tế.
