Description
Technical field
The utility model relates to high-voltage frequency converter technology neck, particularly relates to a kind of high voltage converter bypass switch cabinet.
Background technology
High voltage converter is used widely in each field with the speed adjusting performance of its brilliance, significant power savings.High voltage converter is made up of control cubicle, power unit cabinet, transformer case, bypass switch cabinet, general bypass switch cabinet is made up of vacuum contactor cabinet or vacuum circuit breaker cabinet, cause this bypath system to invest huge, floor space large, control complicated, electrical interlock is unreliable.
Another scheme is made up of isolating switch under isolating switch, power frequency isolating switch, frequency converter on frequency converter exactly, but the interlock function under power frequency isolating switch and frequency converter between isolating switch realizes by mechanical lock, auxiliary switch is arranged on operating mechanism side simultaneously, increase operating mechanism complexity, take very large space.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of high voltage converter bypass switch cabinet.
The technical solution adopted in the utility model is:
A kind of high voltage converter bypass switch cabinet, comprise a cabinet, two isolating switches are provided with in described cabinet, each isolating switch is provided with a connecting lever, this connecting lever connects a connecting rod, connecting rod is connected with the operating mechanism outside cabinet, and this operating mechanism is implemented to switch to isolating switch by described connecting rod, connecting lever successively.
Wherein, described isolating switch is single-pole double throw isolating switch.
Further, described operating mechanism side is provided with electromagnetic lock, lock operation mechanism when this electromagnetic lock is charged for high tension loop.
The beneficial effects of the utility model:
The utility model high-voltage frequency conversion bypass switching cabinet volume is light, internal space layout is reasonable, easy for installation, floor space is little, possess anti-misoperation function, need not install mechanical interlocked with procedure lock device, in isolating switch rotating shaft, auxiliary switch is installed in side, reduce the complexity of operating mechanism, effectively reduce spatial volume, simple to operate, Maintenance and Repair facilitate, invest the advantages such as little, safe and reliable.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
Fig. 1 is the utility model high voltage converter bypass switch cabinet front elevational schematic.
Fig. 2 is the utility model high voltage converter bypass switch cabinet schematic side view.
Fig. 3 is the utility model high voltage converter bypass switch cabinet electrical schematic diagram.
Embodiment
As shown in Figure 1 and Figure 2, for a kind of high voltage converter bypass switch cabinet of the present utility model, comprise a cabinet 6, two isolating switches 1 are provided with in described cabinet 6, each isolating switch 1 is provided with a connecting lever 2, this connecting lever 2 connects a connecting rod 3, connecting rod 3 is connected with the operating mechanism 4 outside cabinet 6, this operating mechanism 4 has one handle and implements to switch by described connecting rod 3, connecting lever 2 pairs of isolating switches 1 successively, operating mechanism 4 side is provided with electromagnetic lock 5, lock operation mechanism 4 when this electromagnetic lock 5 is charged for high tension loop, prevents misoperation.
Be illustrated in figure 3 a kind of high voltage converter bypass switch cabinet of the present utility model electrical schematic diagram.In the technical program, the first isolating switch QS1 are connected to the input of high voltage converter, and the second cutter isolating switch QS2 is connected to the output of high voltage converter, form high voltage converter frequency conversion branch road and power frequency branch road.High voltage converter conversion system runs, and the first isolating switch QS1 in position 3 at position 1, second cutter isolating switch QS2, form frequency conversion branch road and run.When high voltage converter breaks down, the first isolating switch QS1 is switched to position 2, second cutter isolating switch QS2 is switched to position 4, power frequency bypass runs, thus can not affect the normal use of user.
The utility model high-voltage frequency conversion bypass switching cabinet is simple to operate, need not consider the switching locking order between each disconnecting link, possess anti-misoperation function, is convenient to safeguard, invest the advantages such as little, safe and reliable.
The foregoing is only preferred embodiments of the present utility model, the utility model is not limited to above-mentioned execution mode, as long as the technical scheme realizing the utility model object with basic same approach all belongs within protection range of the present utility model.
