IEC standard query, what is the IEC standard?

You go to the "Gongbiao Network" to check your standard number and keywords, the standard input of the Gongbiao Network is very large, and I heard that there are more than 100,000 standards.

Standard number: GB T 15576-2008

Standard name: low-voltage complete set of reactive power compensation device.

Standard Status: Active.

Alternative case: Alternative GB T 15576-1995

Date of implementation: 2009-4-1

Promulgating Departments: China Electrical Equipment Industry Association.

Brief introduction: This standard replaces GB T 15576-1995 "General Technical Conditions for Static Compensation Devices for Low-voltage Reactive Power".

This standard is based on the development of low-voltage complete sets of reactive power compensation devices in recent years and the requirements of low-voltage complete sets of equipment standard GB, and the GB T 15576-1995 is modified and compiled.

This standard specifies the terms and definitions, technical and test requirements of low-voltage complete sets of reactive power compensation devices.

This standard is applicable to low-voltage complete sets of reactive power compensation devices with rated AC voltage not exceeding 1000V (or 1140V) and frequency not exceeding 1000Hz. Compared with GB T 15576-1995, in addition to some changes in the text, some chapters have been added and modified, and the main technical differences involved are as follows:

The rated short-time withstand current of the original centralized compensation device is divided into 80ka, 50ka, 30ka, and 15ka, and the rated short-time withstand current of the device should not be less than 15kVAR when the compensation capacity of the compensation device is not less than 150kvar;

The original discharge facility should ensure that after the capacitor is powered off, it will be discharged from the peak rated voltage to 50V, and the duration shall not be more than 1min, which shall be changed to 3min;

The original verification is that the test power supply voltage should be equal to the rated working voltage when the short circuit is expected, but it is changed to the test method of GB, and the test power supply voltage is expected to be the rated working voltage when the short circuit is expected;

The equipment for non-automatic control switching should be equipped with overcurrent protection;

Increase the minimum requirements for the level of protection of the device;

Added noise test (only for devices with harmonic suppression or filtering function);

Electromagnetic compatibility test added;

Added dynamic response time test (suitable for semiconductor electronic switches and composite switches);

Added phase loss protection test (only applicable to devices with phase loss protection);

Added verification of harmonic suppression or filtering function (only applicable to devices with harmonic suppression or filtering function);

Added Basic Environmental Test (only for outdoor installations).

Generator neutral grounding method.

International Electrotechnical Commission.

IEC, referred to as IEC), is the world's earliest non-national international electrotechnical standardization body, is the United Nations Economic and Social Council.

ecosoc). After the establishment of ISO in 1947, IEC was merged into ISO as an electrical division, but it remained technically and financially independent. According to the new agreement between ISO and IEC in 1976, both organizations are legally independent, with the IEC responsible for international standardization in the fields of electrical engineering and electronics, and ISO in other fields.

IEC standards are: ieInternational Electrotechnical Commission. （international electrical commission）。

Founded in 1906, IEC is the world's earliest non-professional electrical standardization organization, and is the United Nations Economic and Social Affairs Council.

ecosoc). Its purpose is to promote standardization in the field of electrotechnology and electronics in the world.

The origins of the Electrotechnical Commission were the adoption of a resolution at an electrical convention held in St. Louis, USA, in 1904. In accordance with this resolution, the IEC was established in 1906, which was the world's first standardized machine-key configuration.

Organization of the IEC:

The membership draft of the IEC is divided into two categories, one is full membership, and the other is that only one institution is admitted as a member of the IEC in the name of the committee, actively participates in IEC activities, and has the right to vote. To become a member of the IEC, the committee must declare that it is open to all interested or non-governmental organizations in the country interested in participating in IEC activities.

The other type of member is the collaborating member. Due to limitations, it only participates in part of the event. They can participate in all IEC meetings as observers, but do not have the right to vote.

Summary. Hello, dear, the following information** in today's headlines, here for you to find: IEC (International Electrotechnical Commission) standards are international standards developed by the International Electrotechnical Commission to regulate products, systems and services in the fields of electrical, electronic and related technologies.

IEC standards are globally recognized standards for electrotechnical technology and cover a wide range of areas, including power systems, electronic equipment, communication technology, energy management, security, and more.

Hello, dear, the following information** in today's headlines, here Shikong for you to find: IEC (and the International Electrotechnical Commission) standards are international standards formulated by the International Electrotechnical Commission to regulate products, systems and services in the field of electrical, electronic and related technologies. IEC standards are globally recognized standards for electrotechnical technology, covering a wide range of fields, including power systems, electronic equipment, communication technology, energy management, security, etc.

IEC standards are used in a wide range of applications and play an important role in ensuring the quality, performance and safety of products and systems. It plays an important guiding and normative role in the fields of industrial manufacturing and energy, and helps to promote technical exchanges and cooperation between different countries and regions. In the process of product design, production and testing, compliance with IEC standards ensures that the product is noisy and provides easy access to international markets.

What are IEC standards?

IEC standards are International Electro Technical

Founded in 1906, Commission (IEC) is the world's earliest non-national electrotechnical standardization organization, and is a Class A advisory organization of the United Nations Economic and Social Council (ECOSOC).

The IEC has 81 member states (60 full members and 21 associate members), known as IEC National Committees, and each country can have only one body as its member. Each member state is a member of the Council, and the Council meets once a year, called the IEC Annual Meeting, and the Wheel Celery Socks are quietly held in each member state. The Executive Committee deals with matters assigned by the Board of Directors.

The technical work of the IEC is the responsibility of the Executive Committee (CA). In order to improve work efficiency, the Executive Committee is divided into three groups, A, B and C, which deal with the coordination of standard-setting work in different areas at the same time.

The IEC has 95 technical committees and 80 sub-technical committees. China became a member of the Executive Committee of the IEC in 1957. IEC has three certification committees, one is the Electronic Component Quality Accreditation Committee (IECQ), one is the Electronic Safety Certification Committee (IECEE), and the other is the Explosion-Proof Electrical Certification Committee (IECEx).

In order to unify the relevant certification standards, the IEC also established the Conformity Assessment Committee (CAB) in 1996, which is responsible for formulating a series of certification and accreditation standards for Haopai, including system certification.
