3 Terms and definitions

The following terms and definitions apply to this section.

3.1

Windability of winding

The winding performance of the film is used to evaluate the deformation of the rolled film, which can be measured by two aspects: offset/curvature and indentation.

3.1.1

Offset/Arc Bias Camber

When the film is opened flat, its edges do not form a straight line (offset or arc)

3.1.2

depression

sag

When a section of film is supported by two parallel rollers in a horizontal position and subjected to a certain tension, some of the film will be lower than the total

The horizontal plane. Special requirements for joint heat resistance or solvent resistance should be negotiated between the supply and demand parties.

4.4 Tube core

The film should be wound on a circular core, and the core should not shed chips, collapse, or twist under winding tension, nor should it damage the film or reduce its performance

Low. All performance and dimensions of the die, as well as their deviations, shall be negotiated between the supply and demand parties. The preferred inner diameters of the die are 76 mm and 152 mm, and the die can be

Extend the end of the film roll or align it with the end.

5 sizes

5.1 Thickness

Measure the thickness according to the method described in Chapter 4 of GB/T 13542.2-2009, unless otherwise specified in the product standard, and the measured thickness

Should be within ± 10% of the nominal value.

5.2 Width

The inspection rules GB/T 13542 "Thin Films for Electrical Insulation" are divided into the following parts:

Part 1: Definition and General Requirements;

Part 2: Experimental Methods;

Part 3: Biaxially oriented polypropylene thin film for capacitors;

Part 4: Polyester Film

.

This section is the first part of GB/T13542.

This section is modified to adopt IEC60674-1:1980 "Plastic films for electrical purposes - Part 1: Definitions and general requirements" (English version).

The main technical differences between this section and IEC60674-1 are as follows:

1) Added a chapter on 'Normative References';

2) Added a chapter on 'Inspection Rules'.

This section replaces GB/T 13542-1992 "General Requirements for Plastic Film for Electrical Use",

The main differences between this section and GB/T 13542-1992 are as follows:

1) Change 'reference standard' to 'normative reference document'

2) Change "skew" to "offset/arc" in Definition 3.1.1.

This section was proposed by the China Electrical Appliances Industry Association.

This section is under the jurisdiction of the National Technical Committee for Standardization of Insulation Materials (SAC/TC51),

Our drafting units are Guilin Institute of Electrical Science and Dongcai Technology Group Co., Ltd.

The main drafters of this section are Wang Xianxiu and Zhao Ping.

The previous versions of the standards replaced by this section are:

GB/T13542-1992。

6.1 The film should undergo factory inspection and type inspection.

6.2 The type inspection items refer to all the technical requirements specified in the product standard, and shall be conducted at least once every three months. When there is a change in raw materials

When the process conditions change, type inspection should also be conducted.

6.3 The batch size, sampling method, and factory inspection items of the product are specified in the product standard. Each batch of film should undergo factory inspection, and the product should be inspected

Qualified before leaving the factory. The manufacturer shall ensure that the products leaving the factory meet all technical requirements specified in the product standards.

When any of the test results does not meet the technical requirements, a set of samples should be taken from each of the other two rolls of the batch of film to repeat the test

If there is still one group that does not meet the requirements, the batch of films is considered as unqualified.

6.5 The user unit may conduct acceptance inspection according to all or part of the product standards. Preprocessing conditions shall be in accordance with GB/T13542.2-2009

Requirement 3.2 requires it to be carried out.

When requested by the user, the manufacturer shall provide a product inspection report.

7 Marking, packaging, transportation, and storage

7.1 The film roll should be wrapped in moisture-proof paper or plastic film, wrapped in a plastic bag on the outer layer, and placed in an elevated support in the packaging box, so that the film is in normal condition

Fully protected from damage and deterioration under storage and transportation conditions.

7.2 Each box of film should have clear and sturdy markings:

TVS instantaneous suppression protection technology

Multi level cyclic voltage acquisition technology:

After material breakdown, the instantaneous discharge speed is about 1/5~1/3 of the speed of light. The internationally recognized method for collecting breakdown voltage is the voltage drop method. The instantaneous decrease of the primary voltage of the transformer by a certain ratio is used to determine whether the material has broken down. Obviously, there is a deviation in recording the breakdown voltage value. The use of multi-level cyclic acquisition technology to collect the voltage after breakdown will solve this problem.

Low pass filtering current monitoring technology:

High frequency signals will be generated during the high-voltage discharge process. Both domestic and imported current collection sensors are mostly power frequency current sensors. When high-frequency signals cannot be processed during the collection process, it leads to inaccurate detection. Regardless of whether the sensor is designed using a flux gate or Hall principle, there may be an instantaneous output voltage or current signal that is too large after breakdown, thereby burning out the acquisition part of the control system. The low filtering current acquisition sensor developed by Huace processes high-frequency clutter signals accordingly. The protection module independently developed by Huace for same current collection ensures collection accuracy and protects collection components.

● Dual system interlocking technology and isolation shielding technology:

The dual system interlock technology is applied to electrical breakdown instruments. The voltage breakdown instruments produced by Huace not only have overvoltage and overcurrent protection systems, but also have a dual system interlock mechanism. When any component has a problem or a single system fails, the high voltage will be instantly cut off.
