Abstract
The utility model discloses a miniature transformer station and belongs to the technical field of transformer stations. The miniature transformer station comprises a transformer, a high-voltage breaker, and a high-voltage isolator. The output end of the transformer is connected with the input end of the high-voltage breaker. The high-voltage isolator is connected between the transformer and the high-voltage breaker in series. A fuse which is a fuse wire cylinder is disposed inside the high-voltage breaker. In the miniature transformer station, the fuse using the fuse wire cylinder is disposed inside the high-voltage breaker so a worker is safe and easy to replace the fuse wire of the breaker.
Description
Technical field
The utility model relates to a kind of small-sized transformer station, belongs to transformer station's technical field.
Background technology
At present, usually use circuit breaker in the Small Substation, the operation principle of circuit breaker is: when switch contact separates formation electric arc, utilize elongating arc, breaking arc, and horizontal blowing are indulged and are blown magnetic blow-out, electric arc is cooled off, electric arc is carried out " going to dissociate ", final fast extinguish arcs.
Discovery during the applicant uses, when changing the circuit breaker fuse, operating personnel are dangerous, change simultaneously the fuse difficulty, and the unstable properties of fuse.
Further, the applicant finds, primary cut-out breaks down, equipment and position that the attendant usually can not judgement promptly and accurately breaks down.
The utility model content
The technical problems to be solved in the utility model is not enough for prior art, proposes a kind of Small Substation.
The utility model is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of Small Substation, comprise transformer, primary cut-out and high voltage isolator, the output of described transformer connects the input of primary cut-out, the high voltage isolator of connecting between described transformer and the primary cut-out, be provided with fuse in the described primary cut-out, described fuse is fuse unit.
Owing to being provided with fuse in the primary cut-out, fuse adopts fuse unit, and operating personnel can safety when changing the circuit breaker fuse, is easy to change, and simultaneously, has unified the specification of fuse, has guaranteed the stable of fuse performance.
Improvement of the technical scheme is: described primary cut-out is provided with monitoring arrangement.
Because primary cut-out is provided with monitoring arrangement, monitoring arrangement can monitor the signals such as the separating brake, combined floodgate, warning of primary cut-out, in time determines the fault of primary cut-out.
Description of drawings
Be described further of the present utility model below in conjunction with accompanying drawing.
Fig. 1 is the system architecture figure of the utility model embodiment Small Substation.
Embodiment
Embodiment
The Small Substation of the present embodiment as shown in Figure 1, comprises transformer 1, primary cut-out 2 and high voltage isolator 3.
The output of transformer 1 connects the input of primary cut-out 2, series connection high voltage isolator 3 between transformer 1 and the primary cut-out 2.
Be provided with fuse 2-1 in the primary cut-out 2, fuse 2-1 is fuse unit.
During use, operating personnel can safety when changing the circuit breaker fuse, is easy to change, and simultaneously, has unified the specification of fuse, has guaranteed the stable of fuse performance.
The primary cut-out 2 of the present embodiment is provided with monitoring arrangement 4.Monitoring arrangement can monitor the signals such as the separating brake, combined floodgate, warning of primary cut-out, in time determines the fault of primary cut-out.
The utility model is not limited to above-described embodiment.All employings are equal to replaces the technical scheme that forms, and all drops on the protection range of the utility model requirement.
