1. For the charging of the spare bus, when there is a bus tie circuit breaker, the bus tie circuit breaker should be used to charge the spare bus. At this moment, the maintenance device of the bus tie circuit breaker should be fully invested, and the relevant maintenance value and time limit should be changed to a smaller one, so as to facilitate the bus tie circuit breaker when there is a problem, the bus tie circuit breaker can quickly trip, cut ...

The continuity of the aluminum alloy bus duct maintenance circuit is related to the PE line, and the crossover PE wire conductor bus of the maintenance conductor and the two-unit bus bar should reach 50% of the phase line, the equivalent cross-sectional area. The continuity resistance of the housing and PE line maintenance circuit is ≤ 0.005 ohm female, and the unit with jumper wire is not less than the maintenance conductor.

The Wiener comb busbars and connection terminals are available with QUADRON®CrossLinkBreaker in size 000/00 Recommended installation: Wire entry at the lower end of the NH-fuse disconnector through the comb busbar. In the installation position and ...

The bus duct bracket has to be firmly installed, and the bus duct should be correctly placed according to the segment sequence number, phase sequence, number, direction and device mark, and when the sections are connected, the adjacent section of the bus duct should be aligned, and the conductor and shell of the bus duct should not accept mechanical stress after the connection. ...

The modulus of the bus system is 40mm, 60ram, 100/185mm; The bus cross-section is rectangular, double "T" (i.e., "H" shape) and three "T" (i.e., 'state') shapes; The bus system can be three-wire, four-wire or five-wire, or even seven-wire, of course, it should be determined according to the needs ...

1. The standard scale of the bus duct This specification regulates the terminology, skill requirements and test methods of the insulated bus trunk system (bus duct) and its plug-in feed box (hereinafter referred to as the feed box). This specification specification applies to additional voltage AC to 660V...

The grounding of the DC system should include two situations: the one-point grounding of the DC system and the two-point grounding of the DC system. In the DC system, the positive and negative poles of DC are insulated from the ground, and there is no grounding current when generating a ground current when one pole is grounded.

According to the different uses of the bus duct, the bus groove is generally composed of the start bus slot, the straight bus slot (no partition jack and jack), the L-shaped straight (horizontal) curve bus, the Z-type straight (horizontal) offset bus, the T-shaped straight (horizontal) tee bus, the X-type straight (horizontal) cross-way bus, the variable ...

Large power supply capacity up to 6300A current-carrying capacity. 3. High dielectric strength, strong overload, superior fire performance. Good heat dissipation performance, low impedance ...

(1) Single busbar. Single busbar, single bus segment, single bus plus bypass, and single bus segment plus bypass. (2) Double busbar. Double-busbar, double-busbar segmentation, dual-busbar plus bypass, and dual-busbar segmentation plus bypass. (3)3/2 wiring ...

generatrix In the field of electricity, the busbar can also be called the busbar, busbar, etc., which mostly refers to the busbar or power supply trunk in the high and low voltage cabinet, which is used to connect multiple electrical lines. The system will install various interface cards through the bus, and transmit various data to the devices connected to the interface cards.

The use of insulated tube bus in China has a history of nearly 20 years, and it has made a historic contribution to reducing the layout space of the distribution bus and improving the reliability of the bus operation. There are many manufacturers who supply this product, and their production processes are uneven, and the differences in processes are mainly reflected in the ...
