The precautions for the use of oil-immersed test transformers are as follows: 1. Connect the working circuit according to the required test. The shell of the oil-immersed test transformer and the shell of the control box (table) must be grounded reliably. The X-end (high-voltage tail) of the high...

Oil-immersed transformers use oil as the main insulating means of the transformer and rely on oil as the cooling medium (self-cooling, air-cooling, water-cooling). The main reasons for placing pebbles in the oil pit of the oil-immersed transformer are: fire prevention and oil drainage. This part ...

The load switch can’t directly replace the circuit breaker, but it can be used in conjunction with the high-voltage fuse. The main function of the switch is to break the circuit current, such as normal working current, short-circuit current, overload current and so on. For disconnecting hig...

The load switch is a switching appliance between the circuit breaker and the isolating switch. It has a simple arc extinguishing device, which can cut off the rated load current and a certain overload current, but cannot cut off the short-circuit current. The load switch is mainly used to break a...

A high-voltage load switch is an electrical appliance used to control power transformers, and its function is between high-voltage circuit breakers and high-voltage isolation switches. It is often used in series with high-voltage fuses. The high-voltage load switch utilizes the current-limiting f...

Oil-immersed transformer is a new type of high-performance transformer. Oil is used as the main insulation method of the transformer. The main components are composed of iron core, winding, radiator, etc., and are widely used in the power industry. Dry-type transformer is a transformer whose iron...

The working principle of a high voltage load switch is similar to that of a circuit breaker. Generally, a simple arc extinguishing device is installed, but its structure is relatively simple. The picture shows a compressed air high-voltage load switch. Its working process is: when the brake is op...

I’m a firm believer that everyone knows about lightning rods. When we were in junior high school, the textbook introduced it in detail. In our daily life, we often see lightning rods at the top of multi-storey buildings and have the effect of maintaining buildings, but many people have litt...

This product can be used in indoor system of 50Hz and rated voltage 12kV, It can break any fault current between the fuse melting current and the rated break current. It has the current limit fuse merit of high bresking capacity; It has also the non-current limit fuse of small current protection,...

It can be used in indoor system of 50Hz and rated voltage of 12kV, Used togeher with other switch facilities such as loading switches, vacuum contactors, it can protect electric transformers and other electric facilitities against overloading or short circuit. It is also a necessary accessory of ...

XRNT(XDR20)-40.5 High-voltage current-limiting fuse for the wind power transformer protection, applied to ac 50 Hz, rated voltage 40.5 KV power system. As a power transformer and other electric equipment overload and short circuit protection component, mainly installed on the American box change,...

Bay-O-Net Assembly Fuse Holder PRNT5A-15.5 oil-immersed transformer overload protection with high voltage fuse (hereinafter referred to as the fuse) applied to AC 50 Hz, rated voltage 15.5 KV, rated current indoor – 140A high voltage power system. It must connect in series with XRNT515.5 oi...
