High Voltage Surge Resistor and High Voltage Pulse Resistor: A Comprehensive Overview of RV08-6500KJ-185R-K

 

In the realm of electrical and electronic systems, the management of high voltage surges and pulses is of paramount importance. These transient phenomena can wreak havoc on sensitive components, leading to malfunctions, reduced lifespan, and even catastrophic failures. To mitigate such risks, specialized components like high voltage surge resistors and high voltage pulse resistors are employed. One such notable product is the RV086-500KJ-185R-K, a custom-designed resistor tailored to meet specific user requirements while delivering robust performance in high voltage applications.

Product Overview

The RV086-500KJ-185R-K is a custom-manufactured resistor designed to handle high voltage surges and pulses effectively. It is constructed using the RCD07534 series of composite ceramic resistor discs. Each disc has an outer diameter of 75mm, a thickness of 25.4mm, and a central hole diameter of 20mm. With a resistance of 9.25Ω per disc and a power rating of 13W, these discs are precision-engineered to ensure reliability and durability. When 20 such discs are connected in series, they form a resistor component with a total resistance of1 85Ω and a power rating of 260W. This configuration allows the resistor to absorb and dissipate significant amounts of energy, making it ideal for applications where high voltage surges and pulses are common.

Technical Specifications

The RV086-500KJ-185R-K boasts a range of technical specifications that make it suitable for demanding environments. Its temperature coefficient is within the range of (-0.05%～0.15%)/℃, ensuring stable performance across varying temperatures. The voltage coefficient is between -0.5～-7.5%/KV/cm, which means the resistor can maintain its resistance value even under high voltage conditions. It can withstand a maximum energy of 500KJ and has a rated power of 260W. The resistor is designed to operate safely with a surface temperature below 150℃ during long-term operation and below 250℃ during short-term operation. Additionally, it has a specific heat capacity of 2J/(cm³·℃), a chip density of 2.1g/cm³, and a resistance volume of 42cm³.

Environmental Conditions

The RV086-500KJ-185R-K is built to withstand a wide range of environmental conditions. It can operate within a temperature range of -25℃ to +70℃, making it suitable for both cold and hot climates. For storage and transportation, the temperature range is extended to -45℃ to +75℃. The humidity range for operation, storage, and transportation is between 10% and 95%, while the air pressure range is 70kPa to 106kPa. The resistor is also designed to function at altitudes up to 2500 meters, ensuring its reliability in various geographical locations.

Installationations Consider

Proper installation is crucial to ensure the optimal performance and longevity of the RV086-500KJ-185R-K. The resistor is tightly assembled using specialized tools before leaving the factory to ensure good contact between the chips. It is not recommended to disassemble the product without proper authorization. One of the key advantages of this resistor is its ability to handle high energy impacts in a short period. However, it is not designed for continuous long-term operation. Due to the porous nature of the resistor discs, they are prone to moisture absorption. To eliminate any moisture, it is essential to dry the resistor discs in air at a temperature of 110-120℃ for 24 hours before use.

Energy Production in Maglev Systems and the Role of EAK Liquid-Cooled Resistors

Image
Magnetic levitation, commonly known as maglev, represents one of the most advanced transportation technologies of our time. By utilizing powerful electromagnets to lift and propel trains above a guideway, maglev systems eliminate friction, enabling unprecedented speeds and smooth rides. However, behind this seemingly effortless gliding lies a complex energy production and management system. One critical component of this system is the EAK liquid-cooled resistor , which plays a pivotal role in ensuring the safety, efficiency, and reliability of maglev operations. Where Does the Energy in Maglev Systems Come From? The energy required for maglev systems originates from electrical power supplied by the grid. This energy powers two primary components: the electromagnets responsible for levitation and the linear motors that drive propulsion. Levitation Energy : Maglev trains use superconducting magnets or electromagnets to create a magnetic field strong enough to lift the train off the guide...

Understanding Braking Choppers and Liquid-Cooled Resistors in Industrial Drives

Image
In modern industrial automation and motor control systems, managing energy during deceleration is critical for system safety, efficiency, and reliability. Two key components that play a vital role in this process are the braking chopper and the liquid-cooled resistor . These elements work together to ensure stable operation of variable frequency drives (VFDs), especially in applications involving high inertia loads or frequent stopping and reversing, such as elevators, cranes, and conveyor systems. What Is a Braking Chopper? A braking chopper , also known as a brake斩波器 (zhǎnbōqì), is an electronic switch integrated into the DC bus of a VFD. Its primary function is to protect the drive from overvoltage conditions that occur when the motor acts as a generator during deceleration or downward motion (e.g., in lifting mechanisms). When a motor slows down, it feeds regenerative energy back into the drive’s DC link, causing the DC bus voltage to rise. If left unchecked, this voltage spike ca...
