Mainly used in low and medium voltage high current DC transmission and distribution systems, as a key electrical component for connecting or disconnecting isolation between power boxes and electrical networks. DC power transmission and distribution systems have been widely used in industries such as subways, light rails, trolleybuses, metallurgy, atomic energy research and testing institutes both domestically and internationally. They can also be directly used in conjunction with various large DC switchgear and traction box type distribution stations.<BR><BR>The HD26 series DC knife switch is suitable for indoor installation, and its moving contact assembly consists of multiple brake blades with high rebound performance. Both the brake blades and the static contacts are made of electrical copper with silver plating on the surface. At the electrical contact point between the gate blade and the static contact, hard silver contact rivets are riveted on the gate blade, which enables multi-point hard silver point contact when the gate blade is electrically connected to the static contact, ensuring the reliability of electrical contact and good conductivity, thereby ensuring their long working life. The HD26 series DC knife switch is driven by an electric motor. Remote control operation is possible, and manual crank insertion into the corresponding mechanism can also be used for emergency manual operation.<BR><BR>The conductive parts, insulation components, and mechanical load-bearing parts of the HD26 series DC knife switch are made of high-quality materials, ensuring their adaptability to various working conditions. They have the advantages of large fracture surface, high overload capacity, and long working life, making them easy to use in DC switchgear.<BR>The HD26 series DC knife switch meets the standards of GB14048.3-2002, low-voltage switchgear and control equipment isolation switch, IEC50123 DC switchgear, IEC62271-102 high-voltage switchgear and control cabinet.<BR><BR>technical parameters<BR><BR> <TABLE style="WIDTH: 90%; BORDER-COLLAPSE: collapse" border=1 cellSpacing=0 cellPadding=0 width="90%" align=center> <TBODY> <TR> <TD>project</TD> <TD>HD26-2000</TD> <TD>HD26-3150</TD> <TD>HD26-4000</TD></TR> <TR> <TD>Rated voltage KV DC</TD> <TD>one point five</TD> <TD>one point five</TD> <TD>one point five</TD></TR> <TR> <TD>Rated insulation voltage KV DC</TD> <TD>three point five</TD> <TD>three point five</TD> <TD>three point five</TD></TR> <TR> <TD>Rated current KA DC</TD> <TD>two</TD> <TD>three point one five</TD> <TD>four</TD></TR> <TR> <TD>Overload capacity 2 hours KA DC</TD> <TD>three</TD> <TD>four point seven</TD> <TD>six</TD></TR> <TR> <TD>Impulse withstand voltage (1.2/50us) KV DC</TD> <TD>twelve</TD> <TD>twelve</TD> <TD>twelve</TD></TR> <TR> <TD>Mechanical lifespan: (thousand cycles)</TD> <TD>ten</TD> <TD>ten</TD> <TD>ten</TD></TR></TBODY></TABLE><BR> http://www.91way.com/info_en/16912.html knife switch 2026-6-16 12:03:45 HD13B-200 Open Knife Switch<BR><BR> http://www.91way.com/info_en/16910.html knife switch 2026-6-16 12:03:37 HD13B-400 Open Knife Switch<BR><BR> http://www.91way.com/info_en/16907.html knife switch 2026-6-16 12:03:28 HD13B-600 Open Knife Switch<BR><BR> http://www.91way.com/info_en/16906.html knife switch 2026-6-16 12:03:19 <P>The HD13B-1000 open type knife switch is mainly suitable for power isolation and power conversion isolation in distribution circuits with AC 50Hz, rated working voltage of 400V and DC rated working voltage of 230V, rated current of 1600A and below. The performance of this product meets the GB14048.3 standard.<BR><BR>Switches and transfer switches can also carry current under normal circuit conditions, as well as current under abnormal conditions (such as short circuits) for a certain period of time.

suitable for power isolation in industrial distribution equipment with AC 50Hz, rated working voltage up to AC 380V, DC up to 220V, and agreed heating current up to 1600A. Products with arc extinguishing chambers can be used to connect or disconnect AC circuits under specified conditions.<BR>Compliant with standards: GB14048.3-1993, JB8977-1999<BR>Note: For products with arc extinguishing chambers, if used to connect and disconnect DC circuits under specified conditions, users should consult with the manufacturer.<BR><BR>Model and its meaning<BR><A href="/uploadfiles/200808/2008816214646303.jpg" target=_blank><IMG style="FILTER: ; WIDTH: 416px; HEIGHT: 186px" border=0 hspace=0 alt="HD17 series knife switch model description" src="/uploadfiles/200808/2008816214646303.jpg" width=416 height=186></A><BR><BR>Structural features of HD17 series knife switch<BR><BR>The isolators with various operating modes use single blades for 200-400A and double blades for 630-1600A. The contact pressure is obtained by installing leaf springs on both sides. The contacts connected to the blades and external wires are tinned to strengthen surface protection and improve contact resistance with the wires.<BR>The isolator with lever transmission mechanism is equipped with an arc extinguishing chamber for cutting off the rated working current to ensure safety and reliability when disconnecting the circuit. The arc extinguishing chamber is made of insulation cardboard and steel plate grating, which are riveted together. The arc extinguishing chamber is installed by fastening it to the bracket of the spring clip, making installation and disassembly extremely convenient. Isolators of different specifications all use the same type of transmission mechanism, which has clear opening and closing indicators and reliable positioning devices. Each end of the isolator has clear markings for identification.<BR><BR>The central front lever driven isolator is mainly used for installation on the switch board. In order to facilitate the design and installation of the switch board, the longitudinal installation dimensions of 200-1600A are the same.<BR>The installation plate of the isolator is made of phenolic glass fiber compression molded plastic, which has excellent insulation, voltage resistance, and mechanical strength.<BR><BR>Main technical parameters<BR>The rated short-time withstand current of the isolator is shown in the table</P> <P align=center><A href="/uploadfiles/200808/2008816214735196.jpg" target=_blank><IMG style="FILTER: ; WIDTH: 570px; HEIGHT: 128px" border=0 hspace=0 alt="HD17 series knife switch technical parameters 1" src="/uploadfiles/200808/2008816214735196.jpg" width=570 height=128></A><BR><BR>2.
