1Siemens brand history

Siemens is a brand from Germany, founded in 1847 and has a long history of 170 years. Moreover, Siemens entered the Chinese market relatively early, starting from 1872 and has a history of over 140 years. Siemens is also well-known to many consumers in China. For over 140 years, we have won the hearts of numerous consumers and established our market position through continuous innovative technology, excellent user solutions, and high-quality products.

2、 Xierke Industrial Control Equipment (Shanghai) Co., Ltd
HEYTE imports European industrial control products with ultra fast logistics*
SilkRoad24 (Industrial Control Equipment (Shanghai) Co., Ltd.) originated from Silkroad 24 GmbH, a German company established in Braunschweig, Germany in 1999. "Silkroad" is also the Chinese transliteration of "Silk". The founder, CHEN GANG (who holds a master's degree in engineering from Tongji University and Darmstadt University in Germany), has worked for Siemens Automotive and Volkswagen Wolfsburg headquarters in Germany for nearly 12 years and is familiar with the secrets of German industrial automation, large-scale production, and logistics.
In 2005, Xier Ke Business Consulting (Shanghai) Co., Ltd. was established in Shanghai. As the Chinese agent of several European companies such as Ahlborn, Beck, and Honsberg from Germany, Xier Ke has accumulated valuable experience in serving the Chinese industrial automation industry and established a service philosophy based on customer needs. In 2006, in response to the demand of Chinese customers for German industrial spare parts, Xieke Trading (Shanghai) Co., Ltd. was established in Pudong. Taking advantage of the company's headquarters in Germany and years of trade with German suppliers, Xieke Company began to act as an agent for Chinese customers to purchase spare parts for various industries, mainly industrial automation and instrumentation. In order to meet the needs of customers for small amount orders, we have made innovations such as consolidated orders at the source in Germany, centralized agent procurement, warehousing, and centralized customs clearance outside the European Union, which greatly reduces the additional costs for Chinese customers in European spare parts procurement except for the price of goods.
Established in 2014, Xierke Industrial Control Equipment (Shanghai) Co., Ltd. is currently focusing on processing customer inquiries and actively seeking ways to obtain intelligent inquiries and quotations, striving to meet Chinese customers' expectations and supply of various German industrial spare parts prices and delivery times in the absence of warehousing as soon as possible.

IIISIPROTEC 7UM62Series Introduction

SIPROTEC 7UM62 protectionrelayWhat can be done is not just protection. They also provide many additional features. Whether it is ground fault, short circuit, overload, overvoltage, overclocking or underflocking asynchronous situations, protectionrelayCan ensure the continuous operation of the power station. SIPROTEC 7UM62 protectionrelayIt is a compact device developed and designed specifically for protecting small, medium, and large generators.

feature

They integrate all necessary protection functions, particularly suitable for protecting:

Hydraulic and pumped storage generators

Cogeneration plant

Private power plants utilizing renewable energy sources such as wind or biogas

diesel power station

gas power station

Industrial power station

Conventional steam power plant

SIPROTEC 7UM62 includes all necessary protection functions for large synchronous and asynchronous motors as well as transformers.

The integrated programmable logic function (continuous function diagram CFC) provides users with a high degree of flexibility, so they can easily adjust generators, motors, and transformers according to different power plant requirements based on special system conditions. Flexible communication interfaces are open to modern communication architectures and control systems.

The following basic features apply to all versions:

Differential current protection for generators, motors, and transformers

Stator grounding fault protection

Sensitive ground fault protection

Stator overload protection

Overcurrent time protection (timed or inverse timed)

Timed overcurrent protection with directional, undervoltage, and overvoltage protection

Underfrequency and Overfrequency Protection

Overexcitation and Underexcitation Protection

External release coupling

Forward power and reverse power protection

Negative sequence protection

Circuit breaker failure protection

Rotor grounding fault protection (fn, R-measurement)

Motor start time monitoring and motor restart prohibition
