LONGKING High frequency power relay board JDQ (QT) V1.1

1. Product scope of application

The basic function of this equipment is to convert AC power into high voltage DC output. After selecting appropriate electrodes and other mechanical devices, it is a high-voltage electrostatic precipitator equipment that is suitable for various applications such as dust removal, defogging, dehydration, impurity separation, and recovery of rare metals and other raw materials in the industrial sector. It is an important equipment for protecting the environment and developing comprehensive utilization. The specific application scope is as follows:
A, Metallurgical industry: used for dust removal in the smelting of black and non-ferrous metals, recycling of metal smelting raw materials, and their comprehensive utilization.
B, Building materials industry: used for dust removal and raw material recycling in the cement and refractory industries.
C, Electric power industry: used for flue gas dust removal in boilers.
D, Petroleum industry: used for separating salts, water, or other impurities contained in crude oil.
E, Chemical industry: used for recovering valuable components from flue gas, and in the acid production industry for defogging, dust removal, etc.
F, Textile industry: used for alkali recovery and dust removal in papermaking and textile industries.
G, Electronics, pharmaceuticals, and precision machinery industries: used for purifying air and improving product quality.

2. Product Features
This product is manufactured using imported electrical control technology for electrostatic precipitators from GE in the United States. The control part is a digital automatic voltage controller (DAVC controller) composed of MCS-51 series microcontrollers as the core and high reliability peripheral chips. The product has the following main features:
A, It has multiple control characteristics for users to choose from and can adapt to applications in different industries and working conditions.
B, It can automatically distinguish different intensities of flashover and perform corresponding response processing, so as to quickly restore the electric field voltage after flashover and improve dust collection efficiency. Figure 1 shows a typical spark response characteristic.
C, It has multiple fault alarms and protections, as well as self checking and self recovery functions.
D, Adopting light controlled thyristor isolation triggering technology to improve anti-interference ability.
E, Adopting a large printing board structure reduces signal transfer and improves reliability.
F, Set up a six digit LED display to show operating parameters and fault status.
G, Reserve serial communication interface and printer interface, which can be directly connected to a printer to print and output operating parameters (the printer is optional).
H, The controller is installed on the door panel, with a compact structure and easy operation.
