1 Overview
1.1 Product use
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. the product is exposed to conductive parts, all conductive parts are high insulation strength gel epoxy resin or silicone rubber for closed, safe and reliable, the appearance can be touched, no electric shock hazard.
Cable through the elbow plug into the line, through the SF6 switch, insulation closed bus, and then through the load switch, the power distribution out. The cable outlet box can meet the cross-section of 50 ~ 400mm2 the use of power cables, the product can provide a single cable into the line, dual cable entry and exit and other installation methods, with more than 100 kinds of wiring for users to choose. Busbar side can be installed arrester, installation and maintenance is simple, there is no fire hazard, especially for urban areas and high-rise buildings as the distribution of energy use. Is a new type of power distribution equipment suitable for cable supply.
1.2 Product Features and Use
1.2.1 all the charged parts of the line and outlet are completely high insulation strength gel epoxy resin or silicone rubber closed, the insulation layer can withstand all the test voltage, the appearance can be touched, to meet the requirements of long-term operation.
1.2.2 the incoming line can be a solid insulated circuit breaker, or it can be an SF6 load switch. When the SF6 switch into the line, SF6 switch spring operating mechanism by the manual operation, outlet solid insulated circuit breaker with a dedicated operating handle. as long as the operating force of the operating handle is greater than 300N (about 30kg), the dynamic contact of the closing speed will be guaranteed to a certain value, no longer associated with the operating force, thus ensuring the reliability of sub-gate.
1.2.3 Mandatory to prevent misuse. When the switch is in the closed state, can not be grounded, when the switch is in the ground state, can not be closed.
1.2.4 According to the user needs to enter and exit the circuit can be installed short circuit indicator and live display.
1.2.5 cable distribution box is very small, one-third of conventional equipment, the top layer for the double anti-condensation structure, the wall made of stainless steel, never rust. When the installation of the box wall can be removed, cable wiring is very convenient.
1.2.6 the use of a wide range of products, all with SF6 switch, can be used as an outdoor switchgear, you can also increase the insulation of the metering circuit, installed in the box-type substation as a high-voltage switchboard.
1.2.7 No need to disassemble, you can through the special plug to complete the outlet cable routine grounding operation and routine insulation test. It is particularlyConvenient for line search faults.
1.23 this product complies with GB / T11022-1999 "high voltage switchgear and control equipment standard common technical conditions"; GB3804 "3-63kV AC high voltage load switch"; GBl985 "AC high voltage disconnector"; SD318 "high voltage switchgear lock Device technical conditions "; DL / T539" high-voltage switchgear of the common order of the technical guidelines "of the relevant provisions.
2. Installation conditions of use
2.1 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.
2.2 ambient temperature is not higher than +40 ℃, 24 hours an average of not more than +30 ℃. Ambient temperature is not lower than -30 ℃.
2.3 the surrounding media without explosion and flammable danger, not enough to damage the insulation and corrosion of metal gas or steam, no conductive dust.
2.4 installation site 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.
