Cannot break short-circuit current.
The short-circuit current of test power> 5mA, maximum up to 15mA.
Very good dissipation of short-circuit currents 5.
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.
Contact burns when breaking a large short-circuit current.
Prevent large short-circuit currents from burning the fault point.
Circuit(the group line) only on the short-circuit currents.
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.
High voltage digital insulation resistance tester output short-circuit current can be measured directly, without load measurement to estimate.
Can be used to open or close loading current, over-loading current and short-circuit current.
When the internal fault occurs,the sum of the short-circuit currents supplied by each side flows into the differential relay, and the differential relay operates.
RCD-D- protective devices with integrated protection against short-circuit currents or overcurrents.
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;
Output current,(2500V, the output is greater than 25mA), short-circuit currents greater than 40mA.
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.
The VCB is for grade E2,the circuit breaker's breaking short-circuit current with full capacity up to 30 times.
The power transformer is inevitably vulnerable to impulse of various fault short-circuit current or physical collision in the process of operation and transportation andthe transformer windings may lose stability under the powerful electro-dynamic force exerted by such short-circuit current, which could result in permanent deformations such as local distortion, swell or dislocation and will severely affect safe operation of the transformer.
The device using SMPS to formhigh-voltage constant current source, no-load voltage is -15000V, short-circuit current is 30mA.
Important: When installing zeroing must be borne in mind that the short-circuit current must reach the melting insert values fuse or circuit breaker, or the free flow of fault current through the circuit will cause the voltage on all vanishing buildings, and not only on the damaged site.
The dead zone or the malfunction of the protection system causes the transformer winding to withstand the short-circuit current for too long.
It is also widely applied in power plants, substations and power systems with higher short-circuit current as purpose of power controlling/ reception/ distribution.
Therefore, the series resonance can effectively find the insulation weakness, andthere is no big short-circuit current to burn the fault point.
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.
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.
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.
When the parallel resonance or the test transformer method is used for the withstand voltage test,the breakdown current immediately rises several tens of times, and the short-circuit current and the breakdown current are several hundred times different from each other.
When the winding passes a normal load current, the electromotive force Very small, it will not pose a hazard to the windings, but when a short circuit accident occurs,especially when the short circuit point is very close to the secondary exit of the transformer, the short-circuit current will be very large, and the powerful electric motor will cause the transformer winding to vibrate violently and even deform.
Tungsten copper vacuum contacts are subjected to the effects of short-circuits currents and fusing metals in various points of the surface due to the high density of the current in them;
Tungsten copper vacuum contacts are subjected to the effects of short-circuits currents and fusing metals in various points of the surface due to the high density of the current in them; as a result, welding joints form in these zones.
