ABB RED670 touchpad film

Core positioning and technical characteristics

The core positioning of RED670 touchpad film is "industrial grade touch area protection and operation guarantee component". Its design revolves around the three core requirements of "precise touch, strong protection, and long-term durability". Compared with ordinary touch films, it has the following outstanding technical characteristics:

1. High transmittance and high touch precision: using optical grade PET substrate, the transmittance is over 98%, and the haze is less than 1%, ensuring clear and distortion free display content on the touchpad; The surface adopts nano touch coating, with a touch response time of ≤ 5ms, supporting single point precise touch, and an operation error of less than ± 0.5mm, fully matching the touch recognition accuracy requirements of RED670 device.

2. Wear resistant, stain resistant and easy to clean: The surface is covered with a hardened coating with a hardness of 3H, which has undergone 50000 abrasion tests (steel wool friction without scratches) and can effectively resist scratches caused by nails, tools, etc. in daily operations; The coating has oil and water repellent properties, with a surface contact angle of ≥ 110 °, making it difficult for oil and dust to adhere. After being stained, it can be easily wiped clean with a dry cloth to keep the operating interface clean.

3. Scratch and Explosion proof Safety Protection: Adopting a multi-layer composite structure design, with a substrate thickness of 0.125mm and a fracture elongation rate of ≥ 150%, it has good impact resistance. When the touchpad is subjected to external impact, it can effectively buffer the impact force and prevent the glass panel from shattering; Even in the event of accidental damage, the membrane can still adsorb fragments, preventing sharp fragments from splashing and causing safety hazards.

4. Precise adaptation and convenient installation: Accurately cut according to the actual size of the RED670 device touchpad (10.4-inch customized version), with edge tolerance controlled within ± 0.1mm, and a fitting degree of up to 99%; The back adopts a silicone electrostatic adsorption layer, with a residue free design. No professional tools are required during installation, just align and adhere directly. After disassembly, there will be no adhesive stains left on the surface of the touchpad.

5. Industrial grade environmental adaptability: The working temperature range covers -20 ℃~+70 ℃, and can adapt to the high and low temperature operating environment of substations; It has good weather resistance, UV aging resistance (no yellowing after 1000 hours of xenon lamp aging test), and a certain degree of chemical corrosion resistance, which can resist slight industrial common pollutants such as oil stains and alcohol erosion.

Core functions and application value

The RED670 touchpad film, as the "touch protection barrier" of the RED670 device, focuses on the safety protection, operation guarantee, and long-term maintenance of the touch area. The specific core functions and application values are as follows:

1. Core protection function of touchpad

In industrial sites such as substations, RED670 devices often face frequent operations and complex environments. The touchpad film can provide comprehensive protection: preventing operators from scratching the touchpad surface with their nails and preventing accidental tool collisions from causing panel damage; Block dust, oil stains, water vapor, etc. from entering the interior of the touchpad, protect the touch sensing elements from corrosion, and extend the service life of the touchpad. In outdoor control cabinets of new energy power plants, this function can effectively reduce the risk of touchpad failure caused by environmental factors and reduce equipment maintenance costs.

2. Ensure precise and stable touch operation

Its high transparency and precise touch coating design ensure that the display content is clear and visible for operators when viewing device parameters and setting protection settings. The touch operation responds quickly and accurately, avoiding parameter setting errors caused by insensitive touch or operation errors. In emergency operation scenarios of substations, stable touch performance can ensure that operators can quickly complete key operations such as switching on/off protection devices and modifying fixed values, improving work efficiency and operational safety.

3. Reduce the difficulty of daily maintenance

The surface characteristics of oil and water repellency make the touchpad film have good anti fouling ability. It can be kept clean with simple wiping in daily life without the need for special cleaning agents; The wear-resistant coating reduces the wear marks on the touchpad, ensuring that the device maintains a good appearance for a long time. For operation and maintenance personnel, it can significantly reduce the cleaning and maintenance workload of RED670 devices and improve operation and maintenance efficiency.

4. Improve operational safety and reliability

Explosion proof features can effectively prevent glass fragments from splashing and protect operators from injury in the event of accidental damage to the touchpad; At the same time, the insulation performance of the membrane (surface resistivity ≥ 10 ¹² Ω) can reduce the risk of electric shock for operators operating in humid environments. In high humidity distribution room environments, this function provides additional protection for the safe operation of operators.

5. Long term durability reduces replacement costs

The industrial grade material selection and structural design enable the service life of the touch panel film to reach more than 3 years, far exceeding that of ordinary civilian touch films; The installation method of electrostatic adsorption is easy to replace and will not cause damage to the touchpad. When the membrane body is severely worn or stains cannot be removed, a new membrane can be quickly replaced, which greatly reduces equipment maintenance costs compared to replacing the entire touchpad.

Typical application scenarios

RED670 touchpad film is widely used in various power automation scenarios deployed in RED670 devices due to its precise adaptability, strong protection, and industrial grade environmental adaptability. Typical applications include:

1. Substation microcomputer protection system

In the main transformer protection and line protection cabinets of substations of 110kV and above, the RED670 device serves as the core protection unit. Its touchpad film can effectively protect the touch area from wear and tear caused by frequent operation by operators, and resist dust and oil pollution inside the substation; In damp or foggy substation environments, the hydrophobic properties can prevent water vapor from condensing on the surface of the touchpad, ensuring the accuracy of touch operations and ensuring the convenience and reliability of parameter settings and status queries for protective devices.

2. Control scenarios for new energy power plants

In the control unit of the combiner box in photovoltaic and wind power plants, the RED670 device is used to achieve power quality monitoring and fault protection.
