Qinghao electrical substations include Prefabricated substation (PS) and pad-mounted substation (PMS) to provide a reliable and efficient distribution substation for power delivery. We offer a variety of standard designs and configurations, and also can customize for special designs and options. Customer can choose base on site's requirements, such as accessibility, environmental conditions, and the complexity of the installation.
Prefabricated substation is a factory-built electrical substation that is constructed in a controlled environment, usually on-site during construction. The substation components, such as the transformers, circuit breakers, and switchgear, are pre-assembled in a factory, and then transported to the site for installation. The advantage of prefabricated substations is that they can be assembled quickly and with less labor, reducing construction time and costs.
Pad-mounted substation is a standalone electrical substation that is mounted on a concrete slab or pad. The substation components are usually placed on the ground or mounted on a mobile platform, which is then moved to the site. Pad-mounted substations are ideal for sites where a permanent substation is not possible or practical. They are also used in remote locations, such as oil and gas wells or wind farms.
Main Characteristics
1. Compact structure, small size, removable.
2. Power supply safety and reliability: can provide perfect mechanical or electrical linkage, meet the requirement of "five defense", and ensure the safety of the person.
3. Enclosure material is various, design beautiful, under the premise that guarantee the power supply reliability, by selecting the box-type substation shell color thus easy to harmony with the surrounding environment, especially suitable for urban construction.
4. The transformer is mainly ventilated with natural ventilation, and when the temperature of the transformer room exceeds the set temperature, the axial fan on the top automatically starts to control the temperature of the transformer room.
5. The pre-installed transformer substation can be customized according to the user's requirement so the selection scope is large and the market ability is strong.
6. High degree of automation. Protection system using microcomputer integrated substation automation devices, which can realize "four control" of telemetry, remote communication, remote control, remote regulating. Each unit has independent operation function and complete relay protection function. The operation parameters can be set from remote distance to control the humidity and temperature of the enclosure and the smoke alarm meeting the requirements of the unattended. Image remote monitoring can be implemented as needed.
Advantages
1. Compact structure, small size and removable.
2. Safe and reliable operation.
3. Easy for maintenance.
Applications
1. Construction sites, oil fields, ports, terminals,
2. High-rise building.
3. Highways, subways, airports, residential areas.
Service Environment
