DFW1G-12 cable distribution box for 7.2-12kV three-phase AC 50Hz power distribution system, the connection cable, as the acceptance and distribution of electrical energy purposes. No conductive parts of the exposed parts, all conductive parts are sealed with solid insulation material, safe and reliable, the appearance can be touched, there is no risk of electric shock. In 2003 granted the national invention patent, patent number: ZL.200310123001.7 ZL. 2003 10123001.7
2 Applicable standards
this product meets the following national standards: GB / T11022-1999 "high-voltage switchgear and control equipment standard common technical conditions"; GB / T3906-2006 "3-10KV AC metal-enclosed switchgear and control equipment"
3. Installation conditions of use
3.1 the altitude of the installation site does not exceed 2000m.
Note: the installation site of the altitude of more than 2000m, the need to consult with the manufacturer.
3.2 ambient temperature is not higher than +40 ℃, 24 hours an average of not more than +30 ℃. Ambient temperature is not lower than -30 ℃.
3.3 the surrounding media without explosion and flammable danger, not enough to damage the insulation and corrosion of metal gas or steam, no conductive dust.
3.4 installation location without severe vibration and bumps, installation tilt is not greater than 5 ° Note:
for those who do not meet the above conditions of use or special conditions of use of the user, can be resolved in consultation with the manufacturer.
4. Product characteristics and scope of use
4.1 solid labyrinth insulated structure
the structure of the solid labyrinth insulative structure is to set the phase conductor with high voltage in the insulation sleeve of the multilayer structure, and use the labyrinth path between the insulating sleeves to form a large insulation creepage distance. the high voltage is enclosed in a small space. Thereby reducing the overall size of the device.
4.2 sunscreen, anti-condensation, anti-rust box structure
the bottom of the box structure for the double layer, the lower can be ventilated and remove the cable trench within the water and moisture, the upper isolation cable trench moisture and ventilation cooling, so that the box to keep dry. the top layer is double, can be achieved to prevent condensation dripping on the surface of the insulation, and the isolation of strong sun off the exposure, so that the temperature inside the box is not too high. Box wall made of stainless steel, never rust.
4.3 easy to install
When installing the cable terminal, the four sides of the box can be removed as a whole, the cable terminal installation is extremely convenient.
5. Structure
High-voltage cable distribution box by the cable adapter and the box composed of two parts, divided into two types of ordinary and through bus. Ordinary type in the expansion of the circuit when the use of pole way, through the bus-type extension loop is in the same circular bus extension, the conductor section is always the same. so when the current is large, it is suitable to adopt a bus-type structure.
5.1 Cable Tap Construction
5.1.1 the general type cable splitter is made of three insulators made of APG (vacuum injection) method with high insulating epoxy material. the insulator has a plurality of recesses for extending the insulation creep at both ends. A bus bar made of a round copper rod is passed through the center of the insulator and the ends of the insulator are inserted into the insulated outlet sleeve made of silicone rubber. Insulated cover. All live parts are contained in the insulating material, so as to achieve the purpose of insulation closed. (See Figure 1 for the 4-way general-type tapometer outline, schematic 2 ordinary type internal structure of the tap, schematic 3 ordinary type demultiplexer decomposition diagram, schematic diagram 4 ordinary type splitter decomposition diagram, schematic 5 ordinary type Outer box outline)
