Transformers with special applications are commonly referred to as special transformers. In addition to the transformation of AC voltage transformer, there are various other purposes, such as changing the frequency of the power supply, the power supply of rectifier equipment, the power supply of electric welding equipment, the power supply of electric furnace or voltage transformer, current transformer, etc. Because the working conditions and load conditions of these transformers are different from those of general transformers, they cannot be calculated by the calculation method of general transformers. 1, installation, demolition is convenient, covers an area of less, can be installed indoors and outside. 2. High efficiency and energy saving, only a small amount of electric energy is consumed, a large amount of heat can be absorbed in the air, and the power consumption is only 1 of that of the heater
What is an uninterruptible power supply Uninterruptible power supply is a device that provides backup AC power for electrical load equipment without interruption under the condition of abnormal power grid (such as power failure, undervoltage, interference or surge "also known as surge current") to maintain the normal operation of electrical appliances. Features of uninterruptible power supply 1. Green, energy saving, and environmental protection: Under the situation of intensified changes in the world energy pattern, violent fluctuations in international oil prices, and tight global energy supply, energy conservation and environmental protection have become the guiding principles for UPS manufacturers to carry out product technology innovation. For UPS, the input power factor indicates its ability to absorb active power from the grid and the extent of its impact on the grid. Reduce electricity
Emergency lighting centralized EPS emergency power supply shall be equipped with main power, charging, fault and emergency status indicator lights, which shall be green for main power status, yellow for fault status, red for charging status and emergency status. 1. Emergency lighting centralized EPS emergency power supply shall be equipped with main power, charging, fault and emergency status indicator lights, which shall be green for main power status, yellow for fault status, and red for charging status and emergency status. 2. The centralized EPS power supply for emergency lighting shall be equipped with a self-compound test button (or switch-off) that simulates the power supply failure of the main power supply, and no switch that affects the emergency function shall be installed. 3, emergency lighting centralized EPS power supply should be displayed
