What is the function of a busbar expansion joint?

The main elastic element of the bus expansion joint is the stainless steel bellows, which compensates for the axial, transverse and angular direction of the pipe by stretching and bending the bellows, and is widely used in various generators, transformers, switches, buses, high-current electrical equipment, such as electrolytic smelting flexible electrical connections. Its features are mainly:

1. Compensate for the thermal deformation of the absorption tube in the axial, transverse and angular directions.

2. Absorb equipment vibration and reduce the impact of equipment vibration on the pipeline.

3. Absorption of pipeline deformation caused by ** and settlement.

The bus expansion joint has an adjusting effect and avoids the pressure on the equipment node. It is mainly used to compensate for displacements (axial and radial displacements) caused by thermal expansion and contraction of pipes. It is used to protect the normal operation and safety of pipelines.

Shrinkage is to prevent thermal expansion caused by tension caused by short circuit or cold shrinkage of the switch or busbar.

Due to the thermal expansion and contraction of the length of the hard busbar, dangerous stress may occur on the bus porcelain bottle, so the bus compensator (i.e., expansion joint) should be installed. Henan Guomao pipeline equipment manufacturing **** compensator can be made of millimeter copper sheet or aluminum sheet (for aluminum busbar), and its total cross-section should not be smaller than the original bus cross-section. The number of compensators (expansion joints) and the length of the busbar are different depending on the busbar material.

Calculation of the number of compensators (expansion joints) and the length of the busbar.

The function of the plug-in box above the busbar: the plug-in box is constructed with a mechanical linkage control device with the function of safety front hand protection between the box, the box cover, the bus contact and the shunt circuit breaker.

The plug-in box includes:

a. The "sliding plate lock core" snap-on interlocking mechanism for handle operation and plug-in box opening and closing control;

b. The handle operates and controls the circuit breaker to realize the connecting rod linkage mechanism of the shunt circuit "connecting the bird finger on" or "breaking the silver and turning it off";

c. The handle operation restricts the "movable plug" linkage mechanism between the bus contact and its socket to achieve "plugging" or "separation".

The so-called bus plug-in box is that it uses the plug-in method to tap the power supply of the main line to the branch line, so the tap is very convenient.

The plug-in box includes: leather socks.

a. The "sliding plate lock core" snap-on interlocking mechanism for handle operation and plug-in box opening and closing control;

b. The lever linkage mechanism that controls the circuit breaker to realize the "on" or "off" of the shunt circuit;

c. The handle operation restricts the "movable plug" linkage mechanism between the bus contact and its socket to achieve "plugging" or "separation".
