Abstract
The utility model discloses a circuit structure capable of avoiding failure of a high-voltage compensator. The circuit structure is characterized in that aiming at the high-voltage compensator of a cabinet type capacitor, a phase-line fuse is respectively and serially connected onto each phase line of the high-voltage compensator, and corresponding failure phases are cut off when the phase line fuses are short out in a capacitor of the high-voltage compensator. By means of the circuit structure capable of avoiding failure of the high-voltage compensator, a capacitance compensator protected by a microcomputer is ensured to operate safely.
Description
Technical field
The utility model relates to a kind of circuit structure that prevents high pressure compensation device fault; Effectively excise the fault capacitor when more specifically saying so, make non-fault element continue the circuit structure that prevents high pressure compensation device fault of operation to 6KV high-voltage capacitor compensation arrangement internal fault.
Background technology
High-voltage capacitor is one of reactive power source in the electric power system, is used to improve the power factor of electrical network; High-voltage capacitor is in operation and can breaks down; Even blast; Its reason is because phase fault or opposite shell puncture etc. take place in capacitor inside, in order to guarantee safe operation, to 10KV and following high-voltage capacitor; Need on each high-voltage capacitor, be connected in series a fuse, with the internal short-circuit protection device of fuse as capacitor.
Along with the development of technology, in some occasion, capacitive compensator is to adopt Microcomputer Protection control, therefore when dispatching from the factory, is not connected in series fuse on the single high-voltage capacitor at present.In the actual motion, because the capacitor oil impregnate, inside is short-circuited, and the Microcomputer Protection on the capacitor has little time action, causes the capacitor blast.But to this situation, because cabinet type capacitor space is limited, it also is out of the question wanting on single capacitor, to install fuse, and this has brought potential safety hazard to actual motion.
Summary of the invention
The utility model is to adopt the capacitive compensator of Microcomputer Protection control can guarantee safe operation for avoiding above-mentioned existing in prior technology weak point, a kind of circuit structure that prevents high pressure compensation device fault is provided, making.
The utility model adopts following technical scheme for the technical solution problem:
The utility model prevents that the characteristics of the circuit structure of high pressure compensation device fault from being: to the high pressure compensation device that adopts cabinet type capacitor; On each phase line of said high pressure compensation device, be serially connected with the phase line fuse respectively, cut off corresponding fault phase when cabinet type capacitor inside is short-circuited in the high pressure compensation device with said phase line fuse.
Compared with present technology, the utility model beneficial effect is embodied in:
The utility model makes and adopts the capacitive compensator of Microcomputer Protection control can guarantee safe operation, when the capacitor internal short-circuit takes place, through cutting off corresponding fault phase, avoids capacitor to blast.
Description of drawings
Fig. 1 is the utility model structural representation.
Label among the figure: 1 is A phase capacitor; 2 is A phase fuse; 3 is A phase reactor.
Embodiment
The circuit structure that prevents high pressure compensation device fault in the present embodiment is to the high pressure compensation device that adopts cabinet type capacitor; On each phase line of high pressure compensation device, be serially connected with the phase line fuse respectively; Be included in serial connection A phase fuse on the A phase line; Serial connection B phase fuse on the B phase line, and on the C phase line, be connected in series C phase fuse, cut off corresponding fault phase when capacitor inside is short-circuited in the high pressure compensation device with each phase line fuse.
Shown in Figure 1, to the A phase capacitor 1 that inserts the A phase line, serial connection A phase fuse 2 on the A phase line, also promptly outer molten insurance, A phase reactor 3 is provided with device for routine.
