Outdoor power transformation box

Abstract

The invention discloses an outdoor power transformation box, and belongs to the technical field of power transformation boxes. The outdoor power transformation box mainly comprises a box body; a transformer, a low-voltage cabinet, a high-voltage cabinet, a wire outlet cabinet, a capacitor cabinet, a wire inlet cabinet and a monitoring system are arranged in the box body; the transformer, the low-voltage cabinet, the high-voltage cabinet, the wire outlet cabinet, the capacitor cabinet and the wire inlet cabinet are connected with the monitoring system; the monitoring system comprises a microcontroller, a GPRS module, a ferroelectric memory, a switching value input and output module, an analog transmitting output module, a metering chip, a temperature and humidity sensor; and the GPRS module, the ferroelectric memory, the switching value input and output module, the analog transmitting output module, the metering chip and the temperature and humidity sensor are connected with the microcontroller. The monitoring system is additionally arranged; and communication system signals can reach all monitoring terminals through GPRS communication, so that the real-time performance of the monitoring system is improved, and the cost is reduced. The outdoor power transformation box is mainly used for converting a voltage and a current of electric energy.

Description

Technical field [0001] The invention belongs to the technical field of transformer boxes, and in particular, relates to an outdoor transformer box. Background technique [0002] The transformer box is a factory-prefabricated compact power distribution device that integrates high-voltage equipment, low-voltage equipment, and transformers. It has the characteristics of small footprint, strong flexibility, safety and reliability. The transformer box is easy to install and transport, and is widely used in residential communities, towns, factories, docks, oil fields, etc. Due to the compact structure of the transformer box, it is inconvenient for the transformer to dissipate heat, and usually requires a reduced capacity operation. In addition, the existing outdoor substations usually only have the characteristics of power transmission, on-off, protection, and transformation of conventional substation equipment, and do not have the function of real-time monitoring, and cannot meet the...

Problems solved by technology

Due to the compact structure of the transformer box, it is inconvenient to dissipate heat from the transformer, and it is usually necessary to reduce the capacity for operation

Moreover, the existing outdoor substation boxes usually only have the characteristics of power transmission, on-off, protection, and voltage transformation of conventional substation equipment, and do not have the function of real-time monitoring, and cannot satisfy the sampling of power parameters, remote actions of power equipment, Fault location, requirements

Due to the complex geographical location of the outdoor substation box, and there are many monitoring points and a wide distribution range, the communication data is mainly periodic data and burst data, so it has high real-time requirements for the communication of the monitoring system, which is not currently available. solve the problem
