Device for monitoring equipment operation condition of pre-assembled transformer substation

Abstract

The invention discloses a device for monitoring the equipment operation condition of a pre-assembled transformer substation. The device comprises a multi-path switch selector, an embedded singlechip module unit, a computer, a high-voltage chamber main switch condition sensor, a three-phase input voltage sensor, a three-phase input current sensor, a high-voltage chamber ambient temperature sensor and a transmitter, a high-voltage chamber door switch condition sensor, a low-voltage chamber wire inlet power supply voltage sensor and a transmitter, a low-voltage chamber wire inlet power supply current sensor and a transmitter, a low-voltage chamber door switch condition sensor, a low-voltage chamber ambient temperature sensor and a transmitter, a low-voltage chamber output main switch condition sensor, a low-voltage chamber output power metering sensor and a transmitter, a transformer chamber door switch condition sensor, a transformer chamber ambient temperature sensor and a transmitter, and a transformer chamber ambient humidity sensor and a transmitter. In the invention, the device can be used for monitoring the condition parameters of the high-voltage chamber, low-voltage chamber and transformer chamber of the pre-assembled transformer substation in real time.

Description

technical field [0001] The invention relates to a prefabricated substation equipment, in particular to a prefabricated substation equipment operating state monitoring device, which belongs to the technical field of prefabricated substations. Background technique [0002] Prefabricated substation equipment is commonly known as box-type substation, or box-type substation for short. It is a factory prefabricated compact power distribution equipment that integrates high-voltage switchgear, distribution transformer and low-voltage power distribution device according to a certain wiring scheme. equipment together. At present, prefabricated substation equipment is widely used. [0003] Prefabricated substation equipment generally consists of three relatively independent parts: high-voltage power receiving part, transformer step-down part, and low-voltage power distribution part. Therefore, the three relatively independent parts are placed in three spaces, called high-voltage room...
