2 Product application areas

2.1 Power and electrical safety tools

In the power industry, insulating tools are widely used for live work or operations, and the insulation performance of damp and contaminated insulating tools is reduced, which seriously endangers the lives of operators and maintenance personnel. The safety tools and equipment used by the staff during the maintenance and testing of power generation, transmission, transformation, distribution and electrical equipment, including: insulation safety tools, insulation tools, insulation protection appliances, insulation hand tools, testing and maintenance tools .

There are currently several ways to store insulated tools, one is to use wooden or iron cabinets, and the other is to store and keep the insulated tools in the insulated tool warehouse. Wooden storage racks or tool cabinets do not have a long-term constant moisture-proof effect, are extremely susceptible to moisture, and are difficult to meet the storage requirements of insulated tools. Insulation tool warehouse is to store the insulating tools in an independent warehouse, dry them by heating and dehumidification, and then take them out from the warehouse when they are used. However, due to the large investment in this warehouse, the high energy consumption and the slow drying process, especially for There is no need to build a warehouse for insulating tools in units with fewer insulating tools.

According to the chaotic placement of insulation tool rooms in most substations, the placement requirements of live working tools, and the hidden safety hazards of insulated tools due to the environment, we designed a constant humidity automatic control insulation tool. cabinet. Avoid insulation safety tools in power plants or substations from being affected by moisture, deterioration, and dry cracks that affect the performance of storage devices.

3 Product control principle

3.1 Three common principles of traditional dehumidification

1) Heating and dehumidification technology: The method of using a heater to heat the air with an electric heater, using an aluminum alloy radiator to dissipate heat, and the principle of external heat exchange to dry the air in a certain space. This method has high requirements for components, Need high power, easy to add tide.

2) Compression condensation dehumidification: The close relationship between relative humidity and air temperature is used to reduce the local air temperature, so that the water vapor in the local air is released and condensed into water droplets due to condensation, which is then exported to the space, and then the air The temperature returns to the temperature before cooling, so as to reduce the relative humidity at the temperature; this kind of dehumidifier has higher efficiency and fast dehumidification, but the minimum humidity is very unsatisfactory. At 25℃, it can only reach 40 %, the energy consumption is also large, because the compressor or refrigeration device must be used to work, and the fan that causes the air to flow continuously are all energy-consuming electrical appliances, and the noise is also large.

3) Nitrogen dehumidification: Use dry industrial nitrogen to fill a confined space, which can quickly reduce humidity. The advantage is that the humidity decreases quickly, but the disadvantage is that a series of equipment conditions such as a nitrogen bottle pressure reducing valve are required, and the cost is also high. This is a category with consumables.

3.2 The principle of effective new technology molecular sieve dehumidification

The new effective dehumidification technology is to use the solid desiccant molecular sieve to have a great affinity for water molecules in the air. It can absorb the water molecules in the air inside the cabinet for a long time until the molecular sieve is saturated, and then the molecular sieve enters the regeneration state through automatic control. After the molecular sieve releases moisture to the outside of the cabinet (the dehydration regeneration rate is very high), it returns to the dehumidification state inside the cabinet, so that the cycle is repeated, and the humidity inside the cabinet can be reduced to the set value; and the humidification function is correct The molecular sieve heats the cabinet intermittently to regenerate and dehumidify, so that the increase of humidity is a controllable process, so that the humidity inside the cabinet can be accurately controlled. The regeneration times of the solid desiccant molecular sieve are relatively long.

For the process control of moisture absorption and dehumidification, the memory alloy spring is used as the operating element. When the solid desiccant molecular sieve is regenerated, the residual heat of the heating element is used to drive the memory alloy spring to act, and the air door baffle is opened and closed. The structure is simple, and the state of moisture absorption and dehumidification can be flexibly controlled.

From the perspective of energy saving in our design, we fully consider the design of heat insulation and heat dissipation, make full use of energy, can accurately and quickly control the working state of the system, and cooperate with the control of the precise sensor electronic digital circuit to form a set of fast regeneration , A green humidity control system with uniform dehumidification, short cycle and precise humidity control.
