Description

Control and monitoring system for industrial power distribution system {SYSTEM FOR CONTROLLING AND MONITORING INDUSTRIAL POWER DISTRIBUTION SYSTEM}

The present invention relates to a monitoring system, and more particularly to a control and monitoring system for an industrial power distribution system that monitors operating states and power consumption of a plurality of switchboards installed inside a factory and controls and manages them wirelessly.

In a typical industrial site, a plurality of switchboards for supplying and distributing electric power installed inside a factory are widely installed.

Accordingly, there is a problem in that, in order for a manager to operate them, he has to visit and inspect distribution boxes that are widely distributed in a wide factory, and a long inspection time is required.

In addition, there was a time delay between the manager writing the inspection report on site and reporting it using paper, and it was difficult to review numerous papers one by one. Since there is no means, considerable work time is required not only for inspection but also for review and reporting.

In addition, when a problem occurs, a manager must directly go to the distribution box where the problem occurs, check the cause, and take action. This also causes significant losses in terms of management.

And, it can be said that the amount of electricity used in industrial sites is considerable. However, there is a limitation in that even though the total amount of use can be checked using a power meter, it is impossible to check how much was used at a certain point in time. In addition, in order to check the amount of power used, there is a problem in that a manager has to go directly to the place where the power meter is located and check it.

Industrial facilities such as factories use three-phase (R, S, T) AC power, so high power is required. And, as a switchboard for supplying this reduced AC voltage to each facility in the factory is provided, each switchboard usually connects each facility and switchboard to a bus-bar (Bus-bar; 20 and 22), and the AC power reduced in the switchboard is supplied to the facility through the busbars 20 and 22.

As it is connected to the control terminal of the load circuit breaker 17, the load circuit breaker 17 can be turned on or off according to the control signal transmitted from the control box 100, and power can be specified through the mounted power measurement sensor and communication module. The result can be transmitted to the control box (100).

Here, the on-off controller 105 may use a Zigbee system as a wireless communication module that performs data communication with the control box 100 . Since the minimum input signal level required by Zigbee is as low as -92dBm, the signal must be modulated without distortion for a very small input signal, but as it is installed adjacent to the busbar, signal distortion occurs due to power supply.

In order to prevent errors due to signal distortion, a shielding film may be attached to the communication module of the on-off controller 105 in the direction of the bus bar, and the shielding film may be made of a magnesium alloy.
