The full name of ATS is Automatic transfer switching equipment, in the supporting use of the generator set industry. ATS is mainly used in emergency power supply systems to automatically switch the load circuit from one power supply to another power supply to ensure continuous and reliable operation of important loads. SKT series automatic transfer switch is the most advanced third generation ATS. It's of PC Class (one-piece structure). SKT standard type is able to operate the current from 20A to 3200A.
Under normal circumstances, when customers purchase dg genset, they do not know much about the functions of diesel engine generator sets. Some need to start automatically when the power is cut off, and stop automatically when the power comes in. This situation is usually called ordinary automation in our industry. In fact, full automation should have an automatic switching function, that is, ATS. It is mainly fully automated. It will automatically start and automatically close when power genset is off, and automatically open when power genset is on.
ATS is widely used in the generator set industry. What is ATS, and what are its specific functions. We have compiled some easy-to-understand information about ATS for everyone.
The full name of ATS is Automatic transfer switching equipment, and the full name is Automatic transfer switch in Chinese. In the supporting use of the generator set industry, the full name is dual power switch. Automatic transfer switching equipment is abbreviated as ATS, which is the abbreviation of Automatic transfer switching equipment. ATS is mainly used in emergency power supply systems to automatically switch the load circuit from one power supply to another (bai backup) power supply to ensure continuous and reliable operation of important loads. Therefore, ATS is often used in important places where electricity is used, and its product reliability is particularly important. Once the conversion fails, it will cause one of the following two hazards. A short circuit between its power supplier or a power genset failure of an important load (or even a short power outage) will have serious consequences. This will not only cause economic losses (stop production, financial Paralysis), it may also cause social problems (putting life and safety at risk). Therefore, industrially developed countries have listed the production and use of automatic transfer switching appliances as key products to restrict and regulate.
ATS generally consists of two parts: switch body + controller. The switch body is divided into PC level (integral type) and CB level (circuit breaker).
1. PC level: one-piece structure (three-point type). It is a special switch for dual power switching. It has the advantages of simple structure, small size, self-interlocking, fast switching speed (within 0.2s), safety and reliability, but it needs to be equipped with short-circuit protection appliances.
2. CB level: ATS equipped with overcurrent release, its main contact can be connected and used to break short-circuit current. It is composed of two circuit breakers and mechanical interlocking, with short circuit protection function;
The controller is mainly used to detect the working conditions of the monitored power supply (two circuits). When the monitored power supply fails (such as any phase loss, under voltage, loss of voltage or frequency deviation), the controller sends out an action command and switches The main body automatically switches from one power supply to another with a load. The capacity of the standby power supply is generally only 20% to 30% of the capacity of the common power supply.
Nowadays, when customers buy genset engine, they generally want to be equipped with an ATS cabinet. They think this is more convenient and does not require manual operation. In fact, there are several types of ATS cabinets. One is a purely manual ATS cabinet. The generator set is an ordinary unit, and the ATS is also ordinary. When the mains power fails, the generator must be manually started. When the generator is normal , And then manually press the switch button on the ATS panel. Although this method is more troublesome, but the genset power and switch cabinet are not easy to malfunction. The other is the ordinary automatic switch cabinet. The generator set is an ordinary automation. Simply add an electric throttle and an electric switch to the ordinary set. The switch cabinet is also an ordinary switch cabinet. This kind of automatic switch cabinet is relatively cheap, but the failure rate is also relatively high. The other is authentic and fully automatic, and the failure rate is very low. The generator set is fully automated, and the switch cabinet is also fully automated. The price of this type of machine is generally higher, and it is purchased by relatively high-end users.
ATS is usually used in special occasions, such as fire fighting, emergency, banks, financial institutions and other places where power cannot be cut off. In an emergency, once the city power supply is cut off, the ATS will play its role, the emergency will automatically start, and the power supply will be switched to the city power supply. Now we clearly stipulate that diesel generator sets must be equipped with ATS cabinets for fire-fighting acceptance in entertainment-intensive places.Because of the importance of ATS, its supporting products have been listed as key products by the country to be regulated and restricted. Therefore, when a customer purchases a cummins dg generator set, we will ask the customer for the detailed usage, and we have determined whether the customer is equipped with an ATS cabinet. With ATS, the diesel engine generator set can play its due role in special occasions.
General units use diesel generator sets. In order to calculate the cost, ATS is not necessarily required. Some units already have an ATS switch gear in the diesel engine generator room itself. If you buy another silent dg set, it will be wasted. Therefore, when purchasing dg set generator, we should explain the situation to our sales staff immediately to avoid waste.
There are many types of generator sets, and there are different types of generator sets according to different standards. 1. Divided by power source: diesel generator sets, gas generator sets, gasoline generator sets, wind generator sets, solar generator sets, hydroelectric generator sets, coal-fired generator sets, etc. 2. Electric energy mode: According to the converted electric energy mode, i...more
