Description

High Voltage Panel, Low Voltage Panel, Motor Control Panel, Distribution Panel Variable Power Management Switchgear {The variable panel for arranging in a row of high tension, low tension, and motor-control panel}

Switchgear means the safe installation of metal, such as instruments, control switches, protective relays, etc. necessary for distribution.

Conventionally, TIE operation of transformers is performed to minimize the no-load loss that occurs due to the capacity of the transformer regardless of the load.

Conventionally, the parallel operation can be safely performed only when the conditions such as primary voltage, secondary voltage, number of turns, polarity, and capacity ratio of 3: 1 or less are satisfied.

That's why we've typically used transformers of the same model from the same company.

However, in spite of the many advantages of parallel operation, field practitioners are reluctant to parallel operation because of the risk of fire caused by burnout of transformer and heat generation.

In addition, even when the transformer of the same characteristics of the same company is used, there was a problem in parallel operation due to the problem of the burnout of the transformer due to the impedance, frequency imbalance, etc. due to the phase imbalance caused by the load fluctuation and the heat generation.

The task is to enable safe parallel operation even if a transformer is additionally configured that does not satisfy the same characteristics or parallel operation conditions.

Conventionally, even if a transformer of the same characteristics of the same company is used during parallel operation, it solves the problem of the fire caused by the burnout of the transformer due to the impedance frequency imbalance due to the load fluctuation and phase imbalance.

Safe parallel operation is possible even with the use of heterogeneous transformers, and safety is improved through interlocks and safety devices that prevent short-circuits of new concepts different from conventional technologies.

The task is to provide a variable power management system that effectively copes with disasters such as fires and minimizes no-load losses by varying the power system for each transformer according to the characteristics of the load.

Wiring breaker monitors real-time power quality (harmonics, etc.) and power status (leakage current, etc.) for each unit circuit in one unit circuit, and integrates the measurement data of each unit circuit and analyzes power quality such as phase imbalance by phase. Display on the monitor.

Instead of expensive series reactors, low-cost magnetic switches and relays are used to control single-phase loads after circuit isolation, effectively preventing peranti phenomena and power factor drop even under no load or low load.

Even if some circuits are missing, the circuit is switched to a circuit where no phase is lost, enabling temporary operation to prevent the entire power failure.

In addition, in the event of load phase loss, the power failure range is reduced to prevent the entire power failure.

Two or more transformer outputs are input from the program control unit and output to two or more load output stages composed of independent circuits, forming independent distribution lines between loads for each transformer.

Integrated control unit that selects / controls program wiring and program wiring such as single load, parallel load, peak load, single phase load, firefighting, emergency, cooling load, etc. according to the characteristics of output line and load outputted through magnetic switch branched from different transformers This allows safe parallel operation even if the transformers have different characteristics.

The safety of parallel operation is maximized by constructing double safety circuit and short circuit test for maximum safety inside the double safety circuit.

The integrated control unit monitors real-time power quality and power status in each unit circuit and the entire power system, and statistically analyzes the power quality and displays it on the monitor.

Even if there is no load or low power factor, the power factor improvement and the power factor phenomenon are eliminated by controlling the single phase load without using an expensive reactor.

It separates the imaging circuit and converts it into a bypass circuit to prevent the total power failure caused by the missing of some circuits.

The delay time and operating time of the electronic motor protection relay and the parallax control of the integrated control unit prevent the total power failure from the phase loss and the unbalance caused by the load after the electronic motor protection relay.

1. Safe parallel operation is possible even if the transformer characteristics are different.

2. Even if parallel operation is performed with transformers of the same characteristics, it solves the problems of the transformer burnout and heat generation due to load fluctuation, phase imbalance.

3. Safe parallel operation is possible even with the addition and removal of transformers with different characteristics.

4. At least four magnetic switches can implement independent distribution circuits.

   However, in order to realize a double safety circuit, three magnetic switches and a short circuit breaker are additionally required in the case of three-phase seven circuits, but these can be selectively used.The safety of supplying power after a short circuit test inside the double safety circuit Maximization is an unprecedented new concept.

In one preferred embodiment, the nine magnetic switches have distinctive differences and effects from the prior art, and the problem of limiting the number of use of the magnetic switches is economical. Due to the low reliability, the task of reducing the number of magnetic switches is very important.

5. Real-time monitoring and analysis of power quality for unit circuit and entire power system.

6. Eliminate power factor improvement and ferranti without using expensive reactors.

7. If some circuit is missing, switch to bypass circuit to prevent total power failure.

8. Limit the scope of failure to prevent total power failure.

If the load is less than the first input value (e.g., 270 kW) of the programmed input, only the short circuit breaker 7 and the magnetic switch 7 maintain the ON contact point, and the remaining short circuit breakers 1 to 6 and the magnetic switch 1 to 1 6) maintains the OFF contact so that all breakers (loads) are powered through the second transformer.

In the case of the first input value (e.g. 270KW) and the second input value (e.g. 450KW), only the short circuit breaker 1 (90) and the magnetic switch 1 (1) maintain the ON contact, so that all the circuit breakers (load) Power is supplied through the transformer.

To test whether there is a short circuit and if it is safe, switch the contact of the short circuit breaker ON / OFF selection.

In this case, it has safety by switching to the contact point to change the short circuit breaker.

The integrated control unit switches the power factor correction circuit to the OFF contact when the load-side voltage rise exceeds the manager input value according to the load reduction, and separates the power factor correction capacitor from the circuit breaker and short circuit breaker 2 (91), short circuit breaker 3 (92), and short circuit breaker 6. (95) and only magnetic switch 2 (2), magnetic switch 3 (3) and magnetic switch 6 (6) maintain the ON contact.

If an open circuit occurs in the wiring diagram of the first transformer 60, only the short circuit breaker 7 (96) and the magnetic switch 7 (7) maintain the ON contact point. If an open circuit occurs in the wiring diagram of the second transformer, the short circuit breaker 1 Only 90 and the magnetic switch 1 (1) maintain the ON contact, so that operation can be performed even in the case of an open phase.
