Abstract

The invention discloses a dry-type transformer state monitoring device, which comprises a single chip microcomputer, a temperature control circuit, a 433M wireless receiving module, a GPRS wireless communication module, a temperature and humidity sensor, and three current temperature composite sensors, wherein the current temperature composite sensors are arranged at the low-voltage busbar outputend of the dry-type transformer, and the current temperature composite sensors and three phases of the low-voltage busbar output end are arranged in a one-to-one correspondence mode; the current temperature composite sensors are connected with the single chip microcomputer through the 433M wireless receiving module; and the temperature control circuit, the temperature and humidity sensor and the GPRS wireless communication module are all connected with the single chip microcomputer. The traditional detection range is expanded, the composite state of the transformer can be detected in a real-time and online mode, the dry-type transformer state monitoring device mounting process is simplified, and the problem of remote communication between transformers distributed in a vast area range is solved.

Description

technical field [0001] The invention relates to a power transformer monitoring, in particular to a dry-type transformer state monitoring equipment. Background technique [0002] At present, the thermal balance performance of dry-type transformers is poor. The traditional temperature controller of dry-type transformers detects the operating temperature of the transformer windings, drives the fan to realize forced air cooling and alarm control. The dry-type transformer temperature controller is mainly used to protect the dry-type transformer and prevent the transformer from being damaged due to excessive winding temperature. In addition, it also has a comprehensive temperature measurement and display function, which can display the temperature of the three-phase winding, the maximum temperature, the set temperature and the temperature set by the user; it can indicate over-temperature, over-temperature, fault status, and the settings can be changed through the keyboard tempera...
