What is the rated voltage of the generator?

What is the rated voltage of the generator?

As the allowable voltage deviation of the power line is generally +-5%, that is, 10% voltage loss is allowed for the whole line. Therefore, in order to maintain the average voltage rating of the line, the voltage at the leading end of the line can be 5% higher than the rated voltage of the line, and the voltage at the end of the line can be 5% lower than the rated voltage of the line. Therefore, the rated voltage of the generator shall be 5% higher than the rated voltage of the grid at the same level．

According to the installed capacity of difference, generator outlet voltage level are 6.3KV, 10.5KV, 13.8KV, 18.5KV.

What is breaking strength／lcu？

Breaking capacity is generally a circuit breaker or contactor of an electrical index, that is to say, it can be broken in the system short circuit can be broken or can withstand the short circuit current value, GB requirements should bear short circuit under 2 seconds or more can break the load capacity or index.

The difference between class CB and class PC　of Dual power automatic transfer switch(ATS/ATSE)？

First, the principle is different

1. CB class automatic transfer switch is an electronic product that converts one or several load circuits from one power supply to another power supply.

2, PC level automatic transfer switch is one or several load circuit from a power source to another power source of the electrical appliances. Automatic transfer switch (ATSE) : An appliance consisting of a transfer switch device and other necessary appliances for monitoring power supply circuits and automatically switching one or more load circuits from one power supply to another.

Two, different advantages

1, CB level transfer switch appliances, by two circuit breakers as the current breaking unit, and equipped with current trip, with a certain protection ability, the switch on/break capacity of the circuit breaker is much higher than the relay.

2, PC level adopts spring energy storage, instantaneous release of accelerating mechanism, can quickly connect, break circuit or circuit conversion, the product reliable operation performance．

Three, the two are mainly different in the conversion structure mode, basic controller, protection function.

The difference between:

1, PC class ATS adopts integrated conversion structure, excitation drive, simple and reliable, fast action time, generally 100-200ms. The contact is silver alloy, the contact separation speed is high, there is a specially designed arc extinguishing chamber. Small size, only half of CB class, with short-term current resistance.

2, CB class ATS is based on two circuit breakers, controlled by the controller with mechanical interlocking electric drive mechanism to realize the automatic conversion of two power sources. The switching time is 1-2S.

3. PC class has short circuit protection function, while CB class has short circuit protection function.

Extended Information:

Dual-power automatic switching switch is a device controlled by microprocessor for starting switching between network power and network power or between network power and generator power in the power grid system, which can make the power supply continuous source of power supply.

Series DUAL POWER SUPPLY, when the common power failure or power failure, through the dual power switch, automatically put into the standby power supply, (under small load the standby power supply can also be powered by the generator,) so that the equipment can still run normally. The most common are elevators, fire protection, monitoring, lighting and so on.

Double power transfer switch (ATS also known as ATSE, is the abbreviation of Automatic Transfer Switching Equipment) an appliance that converts one or more load circuits from one power source to another.

An APPLIANCE consisting of one (or more) transfer SWITCH appliances and other necessary appliances used to monitor a power supply circuit and to automatically convert one or more load CIRCUITS from one power supply to another. In the electrical industry, it is referred to as "double power automatic transfer switch" or "double power switch".

Field of Application:

ATS is suitable for double power supply of key loads such as fire fighting in the field of construction, and EPS is suitable for EPS is to solve the emergency lighting, accident lighting, fire fighting facilities and other first-level load power supply equipment as the main goal, to provide an emergency power supply system with independent circuit in line with fire fighting specifications.

UPS is mainly used to provide electricity for IT industry equipment, providing clean, uninterrupted backup power. The diesel generator can be used in conjunction with ATS, EPS, and UPS where backup power is needed for a long time.
