Abstract

The invention discloses an automatic feedback control system for the temperature shock of a buffering dry type electric reactor. The automatic feedback control system is composed of a variable-air-speed axial flow fan body (1), a 24-hour real-time online detecting and signal collecting and processing state trigger source (2) and a programmable logic control device (3). The automatic feedback control system has the function of relieving the phenomenon that when a dry type reactor is input and cut off, shock heating and shock refrigerating of the interior of the reactor happen, and therefore turn-to-turn insulation becomes poor, and the automatic feedback control system has the advantages of being safe and stable in operation, compact, low in cost, small in occupied area and high in buffering temperature shock efficiency.

Description

technical field [0001] The invention belongs to the technical field of sudden temperature change of buffer dry-type reactors for electric power. Background technique [0002] Dry-type reactor has the advantages of good linearity, low noise, high short-circuit resistance, and easy maintenance. It plays an important role in maintaining power system voltage stability, limiting short-circuit current, and performing reactive power compensation. It is currently used in power systems widely used. [0003] The turn-to-turn insulation state of a dry-type reactor is a very important factor affecting its safe and stable operation. According to investigation and research, in recent years, a large number of dry-type reactors have been burned frequently. The burning is due to the inter-turn short circuit caused by the inter-turn insulation defect, and the internal temperature of the reactor is suddenly heated and cooled when the reactor is put into and removed. The main cause of inter-t...
