YSF SERIES PRESSURE RELIEF VALVE

New Products / New Technology

The pressure relief valve for transformers is a safety device specifically designed to release the internal pressure of transformers, mainly used in large oil immersed power transformers, power capacitors, reactors and other equipment. Its core function is to timely and effectively release the pressure inside the fuel tank when it exceeds the set value, ensuring the safe operation of the equipment.
Our company produces various models, calibers, and pressure relief valves for opening pressure, with product models ranging from YSF4 series to YSF16 series; The main fuel injection diameters are 25mm, 50mm, 80mm, and 130mm; The opening pressures are 15kPa, 25kPa, 35kPa, 55kPa, 70kPa, 85kPa, and 138kPa. In addition to conventional electrical alarm signals, the product can also add computer electrical alarm signal function, which can achieve dual electrical signal output and convert pressure value changes into 4-20mA analog output. It can also be configured with RS485 communication protocol.
Our company's pressure relief valve features: integrated electrical switch, strong safety and reliability, good three proof performance, and easy wiring. We can provide special customized services according to customer needs for temperature adaptation, special environments, contact capacity, output methods, wiring methods, etc.

QJ SERIES GAS RELAY

New Products / New Technology

Buchholz relay, also known as Buchholz relay, is a component that uses the hot oil flow and hot gas flow generated when the transformer is faulty to promote the action of the relay, and it's a transformer protection device.
Our company now produces diameter φ25mm, φ50mm, φ80mm Buchholz relay, can be used in transformer switch, transformer, transformer body. The memory function is also added to prevent problems in the secondary circuit that lead to heavy gas action signals. In addition to mechanical magnetic induction, it can also convert gas volume changes into 4 ~ 20mA analog output through digital electrical signals, and can also configure RS485 communication protocol, which meets the needs of national smart grid construction.

YZF SERIES POINTER-TYPE OIL LEVEL GAUGE

New Products / New Technology

YZF series transformer pointer type oil level meter is used to measure the transformer oil level instrument, its main structure includes: feeling part (straight rod float), transmission part, magnetic coupling, indicating part, alarm part of the composition, our company's products according to the diameter of the disk is divided into: φ90mm, φ140mm, φ200mm, φ250mm four specifications, respectively, suitable for different diameters of oil storage tanks.
According to the swinging form of the connecting rod, it is divided into two kinds: up and down swinging and left and right swinging, which are suitable for the main oil storage tank and the on-load switch oil storage tank. The structure of the connecting rod is straight rod float ball type, which is suitable for capsule type oil storage tank.
Transformer pointer type oil level meter features accurate measurement, durable, alarm warning, temperature warning and so on.
