The difference between high-voltage load switch….
It is a three position load switch special for the GIS.
Table 2 Main mechanical characteristics of load switch.
What is the difference between the load switch and the vacuum circuit breaker?
Equipment for disconnecting the current load. Load Switch.
FN12-24RD series load switch can be installed with earthing switch. .
The difference between high-voltage load switch… Navigation.
Both the load switch and the vacuum circuit breaker can open and close the rated current.
The difference between high-voltage load switch and vacuum switch[May 24, 2018].
The load switch carries a small current of 0~125A, and the vacuum circuit breaker carries a large current of 0~5000A;
Table 1 Main technical specification of load switch and earthing switch. .
High-voltage load switch is suitable to install in ring main unit and other switchgear types, used as accepting and distributing power.
When one or more phases of fuse melted down,three phases of load switch open automatically.
The average mechanical life of the load switch is up to 1000 times, and the vacuum circuit breaker can reach 10,000 times;
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;
FN12-24RD type indoor AC high-voltage vacuum load switch and its composite apparatus is three phases AC 50Hz, rated voltage of 24KV.
The load switch with high technical parameters and reliable movement, its basic operating type is by manual, but also can be equipped with electromagnet spring operating mechanism.
In particular, in the middle-mounted switchgear,the conventional fuser(or fixed load switch) is used to protect the station transformer(or grounding) more reliably.
High-voltage load switch is suitable to install in ring main unit and other switchgear types, used as accepting and distributing power.
The earthing switch has the same capability of short-circuit making anddynamic stability with load switch, and has strict mechanical interlock with load switch, which structure ensure no misopertion.
The load switch is used in places where frequent opening and closing operations are not required, and the vacuum circuit breaker can be used in places where frequent operation is required.
The operation table can test the temperature rise test of switch cabinet, ring network cabinet, cable branch box, circuit breaker, load switch, isolation switch, On-column switch and other large current switch node equipment, which can meet the large current temperature rise test of switch cabinet maximum 5000A,circuit breaker 5000A, load switch 5000A, isolation switch 5000A, On-column switch 5000A.
Screen load switch, but the cut-off time should not exceed 3 seconds, regardless of whether the loop is grounded or not, if the DC grounding phenomenon of the switch is removed, the grounding point can be judged on the busbar, and then the pull can be sequentially Open all the open-circuit DC power supplies on the busbars, and then determine the exact grounding open circuit and effectively handle it to completely eliminate the grounding phenomenon.
FN12-24RD series HV puffer-type load switch and its composite apparatus is AC 24kV, 50Hz indoor high-voltage switch. .
RAF-12/630 pole-mounted load switch is suitable for rated voltage 12kV, rated current 630A and 50/60Hz distribution system, and used for making and breaking disconnected, load current/overload current in the power system.
Whether it is to find the grounding in the DC screen with the load switch or the next level load in the DC screen with the load switch, you must adhere to the DC system to find the grounding principle.
Isolation switch, vacuum load switch, grounding switch and cabinet door have perfect and reliable mechanical linkage and interlocking device, which can effectively prevent misoperation and ensure safe maintenance.
Under normal circuit condition, high-voltage load switch can make, bear and break load current, and has 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, and has the ability to make short-circuit current, and bear short-circuit current in certain times.
The VZF(R)-12 series vacuum switch adopts the removable installation method, which changes the history that the load switch can not be used with the central circuit breaker, and changes the history of the secondary power distribution system without the central ring network cabinet. In particular, in the middle-mounted switchgear,the conventional fuser(or fixed load switch) is used to protect the station transformer(or grounding) more reliably.
