These sections must not exceed 2-2.5m. Measures must be adopted against the drop of contact pressure taking into account that busbars will expand in joints that are made during reassembly of groups.

When main busbars (phase busbars) are formed of a single busbar, calculations related to auxiliary busbars are not necessary. In this case, main busbar is the auxiliary busbar at the same time.

The photograph above belongs to busbar assemblies to which E-Kabin B Series type tests are applied and it shows that busbars themselves are subjected to mechanical forces. It is seen that Auxiliary busbars are inclined to each other.

Current information;

• Busbar assembly whose short circuit mechanic strength will be calculated consists of 2 pcs of busbars (with a cross-section of 100x10mm) per phase.

• Distance between phase axis is 150mm.

• Short circuit current is unknown; however it is known that the transformer supplying the entire plant has a power of 1000kVA.

• Busbar assembly was supported on two lateral planes of each switch cabinets. The widest switch cabinet has a width of 600mm.

In light of this information, the calculation of the short circuit mechanic strength of the mentioned busbar assembly is as follows, based on certain assumptions.

Assumptions:

• Effective short circuit current can be calculated in the following way, assuming that there is short circuit right in the output terminals of the transformer:

i’’k3 [A] 25 x SnT [kVA] = 25 x 1000 = 25.000[A] = 25 [kA]

• Busbar material is assumed to be E-Cu F30.

• It is assumed that busbars are positioned in a way to slide on insulators and constrained be tween the two insulators.

• It is accepted that no other reinforcement piece apart from the support points is used between two busbars that constitute the phase conductor or no supports are provided by making another busbar output.

Values that form the basis of the calculations;

Busbar cross-section 100 [mm] x10 [mm] Number of busbars in the phase n=2

Sample Calculation

If the short circuit strength of insulators is not demonstrated by means of testing, it should be demonstrated by calculation that the force on support points is less than the strength force supplied by the insulator manufacturer.

2. Result; Insulators need 5349 [N] (approximately 535kg) peak force in order to resist short circuit current.

Comments

In low voltage electricity switch enclosure en-closures, the 200°C limit that is generally set for copper is not forced. In many applications, there are measures to ensure that short circuit currents end in 1 sec.

Besides the thermic resistance of copper bus-bars, another important issue is the resistance of insulator material that is in contact with them. The said heating is brief. In this context, short term thermic resistance of insulator material must be high enough.

Short circuit thermic resistance calculation of copper busbar assemblies

Short circuit currents can heat copper busbars up to high temperatures. Temperature level reached after short circuit is propor-tionate with short circuit period and the temperature at which short circuit starts. Allowable maximum temperature for copper busbars is 200°C.Maximum current amount that can flow from a busbar assembly after short circuit according to EN 60865 (1993) is calculated as stated below depending on short circuit time. Here, calculation is made with current intensity values in order to be independ-ent of cross section calculations used in the said busbar assembly.

Sample calculation:

Calculation of maximum short circuit current that can flow for 3 seconds from a busbar assembly that contains two 100mmx10mm copper busbars that are allowed to heat up to 70°C in operating conditions and 140°C in short circuit condition in each phase is shown below.

Use of type tested isolators in type tested switch enclosures

IEC 61439-1:2011 standard that is used to prove technical capability of switch enclosures describes the tests to be applied on switch enclosures in details.The test related to proving short circuit resistance among the said tests is described in section 10.11 of this standard.E-Kabin B Series insulators’ short circuit resistance is proven with “verification by testing” method.IEC 61439-1:2011 standard article 10.11.4 describes “verification by comparison with reference design”. Accordingly, evaluation of rated short circuit resistance current of board and circuits must be carried out by comparing a board verified by testing” with the board to be evaluated. Verification evaluation of main circuits of a board must be according to “Annex P” section, i.e. IEC 60865-1 of the standard. Each of the circuits of the board to be evaluated in addition must meet the specifications below.Are the short circuit protection assemblies of each circuit of the board to be evaluated, the same and better limiting characteristics taking assembly manufacturer data as basis (I2.t.Ipk) equivalent to same reference design such as manufacturing and series?

- If the board to be evaluated includes a housing, does the reference design include one when verified by testing?- Does the housing of the board to be evaluated have the same design, type and same dimensions at least?- Do the cells of each circuit of the board to be evaluated have the same mechanical design as the reference design and same dimensions at least?

E-KABIN B serıes type tested isolators

E-Kabin B Series low voltage insulators are designed by EAE. They are subjected to approximately 80 circuit type tests in IPH Berlin and KEMA Netherlands laboratories. There are various types of insulators in different circuit current values in E-Kabin B Series to be used for different purposes and methods.

E-Kabin B Series insulators have modular design to meet all kinds of needs for low voltage electricity switch enclosure busbar applications. Distances between phases can be changed.

In order to use short circuit type tested E-Kabin B Series insulators in partially type tested switch enclosures by comparison with calculation, requirements stated in article 10.11.4 of IEC 61439-1:2011 standard must be met.

1) E-Kabin B Series Insulators are tested in very high short circuit currents. The short circuit current that each insulator type is tested at is given in related technical specifications page. There are insulators resisting maximum 150kA.2) Conductive current intensities related to thermic resistances of E-Kabin B Series insulators during type tests are given in related technical specifications page. Insulator thermic resistance can be proven when desired by calculating compared busbar assembly current intensity. During this calculation, it can be seen that very high current intensities are used in type tests.3) Material and manufacturing quality of E-Kabin B Series insulators is under EAE warranty.4) It is mandatory for switch devices to be connected to busbar assemblies that will be compared to be type tested and that busbar connections made with them are compliant with technical documents of manufacturers.5) Short circuit resistance of the said busbar assembly must be proven by calculating according to IEC-60865-1. Also, there are graphics that show maximum support gaps for distances between different phases on related technical specifications pages.
