Contact burns when breaking a large short-circuit current.
To prevent large short-circuit current burn failure point.
Thermal resistance to the calledground short-circuit current.
Compared with the two, the short-circuit current is several hundred times different from the breakdown current. .
Opening, closing the rated current, and breaking the short-circuit current.
A short-circuit current is interrupted by protection devices(fuses or automatic switches) within the time set according to the tripping characteristic.
The VCB is for grade E2,the circuit breaker's breaking short-circuit current with full capacity up to 30 times.
In breaking up the large short-circuit current; usually the arc can be extinguished before the short circuit current has not reached the maximum value.
Can be used to open or close loading current, over-loading current and short-circuit current.
Measurement of Capacitive Tests Because the output short-circuit current is greater than 1.6mA, it is easy to rapidly increase the test voltage to the rated output voltage.
The device using SMPS to form high-voltage constant current source,no-load voltage is -15000V, short-circuit current is 30mA.
The protection and control switchgear,usually eliminate the short-circuit current in less time than 1 second through protective relays and operating devices.
The dead zone orthe malfunction of the protection system causes the transformer winding to withstand the short-circuit current for too long.
The load switch does not need to break the short-circuit current, so it is not equipped with protection device and automatic device, and basically does not use remote operation;
Therefore, the series resonance can effectively find the insulation weakness, andthere is no big short-circuit current to burn the fault point.
However, it cannot disconnect the short-circuit current, so it is generally used in series with a high-voltage fuse, and it is protected by a fuse for short-circuit protection.
The reason for this may be that the test piece is short-circuited under high voltage and the short-circuit current is large, so all the lights are on.
When the transformer is subjected to the impact of short-circuit current or in the course of transportation, it is possible to have the phenomenon of winding deformation, which will directly affect the safe operation of the transformer.
Fault current limiters are ideal devices with electrical characteristics that can help to solve this problem of high short-circuit current levels.
For the terminal station especially,because of its low rated current and rated short-circuit current, like"waste one's talent on a petty job", far from economy.
In the closed position, it can carry the normal circuit current and, for a specified time,even an anomalous circuit current, such as, for example, a short-circuit current.
It is also widely applied in power plants, substations andpower systems with higher short-circuit current as purpose of power controlling/ reception/ distribution.
If there is something wrong on any part of the power system, the switchgear must operate quickly so that no damage is done to generators, transformers andother equipment by the short-circuit current.
For a correct use of MASTERBOX assemblies the installer must check that the assumed short-circuit current at the connection point to the assembly is less that or equal to the cut-off device's breacking capacity.
Rated short-circuit making capacity, I cm(kA) this refers to switchgear anddisconnect switch for a closing operation on specified peak short-circuit current values.
When the overload current or short-circuit current goes through the fuse, the fuse melts and arc is generated in the tube, the quartz sand has a strong cooling effect on arc and deionization, the arc soon extinguished.
Under normal circuit condition, high-voltage load switch can make, bear and break load current, andhas the ability to make short-circuit current, and bear short-circuit current in certain times.
Rated fused short-circuit current I cd- the presumed current that a device associated with a fuse can withstand, without damage, for the duration of the latter's operation, under the specified test conditions;
The isolation switch does not have a special arc extinguishing device andcannot cut off the load current and the short-circuit current, so the circuit must be disconnected in the circuit breaker.
This product has the lack of protection function,when the short-circuit current or load current flows through the main circuit in which any one or more phases of the fuse is blown, the impactor motion, energy output and rapid impact load interlock switch, the load switches gate.
