Abstract

The invention discloses an intelligent monitoring system for a power distribution room. The measurement and control functions of the low-voltage side and low-voltage outgoing line of a distribution transformer can be realized by using an intelligent controller and a concentrator; detection of phase loss, zero break, overload, electric leakage can be realized; and the releasing of an ordinary molded case circuit breaker can be controlled, so that protection can be performed on personal security and user equipment, and user faults can be prevented from enlarging to affect medium voltage power grids. A controller is connected to the concentrator through zigbee in a wireless manner, and data can be transmitted to a user mobile phone APP through a GPRS after collected by the concentrator, so that the real-time monitoring of the operation states of low-voltage outgoing line switches can be realized; and through the adoption a plurality of technological means such as self-describing protocols, wireless transmission, multi-device cascade, CT open circuit overvoltage protection, clip electricity taking, integral fixation of the controller and CT, on-site installation without power failure,the reduction of line paving due to wireless interconnection, and unified protocols for easy debugging can be realized, so that construction efficiency can be greatly enhanced.

Description

technical field

[0001] The invention relates to the field of power distribution room monitoring, and more specifically, to an intelligent monitoring system for a power distribution room. Background technique

[0002] With the continuous improvement of the automation coverage of the power system, the intelligent monitoring equipment configuration of the medium-voltage switchgear is relatively complete. The line inspection department can monitor the operation status of the medium-voltage power grid in real time through the automation system, and automatically isolate faults, which improves power supply reliability. However, the low-voltage outgoing lines are generally not equipped with intelligent controllers with communication functions. The transportation inspection department knows nothing about the operation of the user lines and cannot obtain the power consumption of the user lines in time. The company receives many complaints.

[0003] A large number of ordinary molded...

Examples

Embodiment 1

[0039] An intelligent monitoring system for power distribution room, such as figure 1 , including remote terminals, concentrators, environment acquisition modules, equipment status acquisition modules and several intelligent controllers, of which:

[0040] The remote terminal is connected to the concentrator through GPRS communication. The intelligent controllers are respectively installed on the low-voltage side of the distribution transformer and each low-voltage outgoing line, and collect the voltage and current of the low-voltage side of the distribution transformer and each low-voltage outgoing line, and collect them in the concentrator. , the plurality of intelligent controllers control the opening and closing states of the low-voltage outlet switches;

[0041] The environmental collection module collects the environmental information of the power distribution room and converts it into an electrical signal, and then transmits it to the concentrator through wireless commu...
