Intelligent distribution transformer

Abstract

The invention discloses an intelligent distribution transformer, solving the problem that the current transformer state information cannot be transmitted. The intelligent distribution transformer is characterized in that: the box cover of the distribution transformer 1 is provided with an on-load capacity regulation and voltage regulation tap switch 2 and an intelligent liquid level temperature sensor 3; the on-load capacity regulation and voltage regulation tap switch is connected to a device for online monitoring current and voltage of the distribution transformer consisting of a power distribution box, a full optical fiber current mutual inductor, an optical voltage mutual inductor and a combined unit. The intelligent distribution transformer precisely measures current and voltage on the secondary side of the power distribution transformer, returns the feedback to the on-load capacity regulation and voltage regulation tap switch, enables the on-load capacity regulation and voltage regulation tap switch to perform switching between the big capacity and the small capacity according to the change in the load and determines that whether the operation state of the transformer is faulted according to the temperature and the liquid level signal, promptly gives the feedback to the industrial control system and realizes the intelligent regulation of voltage and capacity.

Description

technical field [0001] The invention relates to a distribution transformer, more specifically to an intelligent distribution transformer capable of automatically processing according to load changes. Background technique [0002] Existing distribution transformers are generally installed in remote locations, and the transformer is a high-voltage electrified body, which cannot be monitored during operation. The body of the oil-immersed transformer is immersed in the insulating liquid. The main material of the insulation is the liquid insulating liquid. If the liquid level is insufficient or the temperature of the insulating liquid is too high, the insulation strength of the transformer will decrease, which will threaten the safety of the transformer operation and increase the probability of an accident. Since the status information of the transformer cannot be transmitted, frequent inspections are required to ensure safe operation. Contents of the invention [0003] The p...
