Voltage transformer self-checking protection device

Abstract

The invention discloses a voltage transformer self-checking protection device which comprises a voltage transformer and a hand-held terminal, wherein a single-chip microcomputer is installed in the voltage transformer, the single-chip microcomputer is provided with a storage part, a voice alarm and an MCU central control unit, the single-chip microcomputer is electrically connected with a wireless module and a power supply module, the single-chip microcomputer is electrically connected with a temperature probe, the single-chip microcomputer is electrically connected with an input and output mechanism, the power supply module is electrically connected with the voltage transformer, the wireless module comprises an antenna, and the antenna is in signal connection with the handheld terminal. By designing the voltage transformer with the self-checking protection device, when the temperature of the voltage transformer is abnormal, information can be sent in time, and all information of the abnormal transformer is sent to the handheld terminal together, so that a worker can master the information at the first time, and the voltage transformer can be maintained in time.

Description

technical field [0001] The invention belongs to the technical field of voltage transformers, and in particular relates to a self-checking protection device for voltage transformers. Background technique [0002] As a contact component between primary equipment and secondary equipment, voltage transformers play an irreplaceable role in power systems. The voltage transformer has the following burning situations during operation and use: (1) The service life of the voltage transformer is too long, the insulation is aging, local breakdown or discharge occurs, and a large current is generated, which causes the voltage transformer to heat up and burn out; (2) The user is overloaded for a long time, causing the voltage transformer to heat up and burn out. In order to avoid electric accidents caused by such situations, a voltage transformer self-test protection module has been developed for this situation. [0003] At present, some voltage transformers are equipped with anti-short...
