The utility model relates to overvoltage protection device field, particularly a kind of sectional mo(u)ld overvoltage protection device.
Background technology
In recent years, along with the development of society, economy and switching technique, the complexity of engineering construction strengthens, and miniaturization, non-maintaining, intelligentized switch cubicle are more and more favored.Do not losing under the prerequisite of switch cubicle performance and insulation, the inevitable installation dimension of the interior product of cabinet and element that just requires of miniaturization of switch cubicle is more and more less, and electric elements are by development for many years, substantially be tending towards now ripe, in this case, just the variation of the mounting means of the high pressure components and parts in cabinet has been proposed to higher more requirement.And the overvoltage protection device of general expression adopts zinc oxide core body; with advantages such as its large through-current capacity, low residual voltage, fast response times, capturing high voltage protective electrical equipment market, but its unalterable volume and profile have been brought great inconvenience to design and the installation of switch cubicle always.
Utility model content
The purpose of this utility model is to provide a kind of sectional mo(u)ld overvoltage protection device, can solve volume and profile that existing overvoltage protection device is unalterable, brings great convenience can to design and the installation of switch cubicle.
In order to achieve the above object, the utility model is achieved by the following technical solutions.
A sectional mo(u)ld overvoltage protection device, is characterized in that, comprises unit, protector ground, three protector facies units, and unit, described protector ground, three protector facies units are four independently functional units; Described each functional unit bottom is provided with end box, is provided with for the electrode column and the electrode slice that are electrically connected between functional unit in end box; Described four functional units are electrically connected to by described electrode slice and electrode column in box of the corresponding end respectively.
Feature of the present utility model and improvement are:
The non-linear resistor that unit, described protector ground, three protector facies units are stacked by multi-disc is respectively packaged in insulated tube and forms, and a sulfidization molding is fixed on end box.
Described protector unit, ground and three protector facies units " " font are arranged and are electrically connected to, and four ground boxes of its correspondence are all cast with epoxy resin.
Described protector unit, ground and three protector facies units " T " font are arranged and are electrically connected to, and four ground boxes of its correspondence are all cast with epoxy resin.
Described protector unit, ground and three protector facies units " L " font are arranged and are electrically connected to, and four ground boxes of its correspondence are all cast with epoxy resin.
Described protector unit, ground and three protector facies units " mouth " font are arranged and are electrically connected to, and four ground boxes of its correspondence are all cast with epoxy resin.
In sectional mo(u)ld overvoltage protection device of the present utility model; unit, protector ground, three protector facies units are four independently functional units; can and install according to user's needs design; product mix is become to the multiple mounting modes such as " ", " T ", " L ", " mouth " font; bring great convenience to user's design and installation; solved after switch cubicle miniaturization the limited difficult problem of installing space in cabinet.
accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of sectional mo(u)ld overvoltage protection device of the present utility model;
Fig. 2 (a), Fig. 2 (b), Fig. 2 (c), Fig. 2 (d) are four kinds of splitting modes of the present utility model;
Fig. 3 is circuit theory diagrams of the present utility model.
embodiment
See figures.1.and.2 (a), Fig. 2 (b), Fig. 2 (c), Fig. 2 (d), this sectional mo(u)ld overvoltage protection device comprises three protector facies units, protector ground cells D, three protector facies units, cells D be four independently functional units; Each functional unit bottom is provided with the end box for cellular installation, is provided with for the electrode column and the electrode slice that connect between functional unit in end box; Four functional units are electrically connected to by described electrode slice and electrode column in end box.Due to three protector facies units, cells D be four independently functional units; three protector facies units and protector ground cells D can by electrode slice and electrode column according to user need to carry out " one ", " T ", " L " or " mouth " glyph group is combined, and forms a complete overvoltage protection device.
Three protector facies units, in cells D, each functional unit is that after the non-linear resistor that stacked by multi-disc is packaged in insulated tube, one time sulfidization molding is fixed on end box; After end box interconnector, all, with epoxy resin pouring, to ensure dielectric strength, guaranteed that other performances of overvoltage protection device can not be affected.
With reference to Fig. 3, circuit theory of the present utility model is described.N point is the artificial neutral point arranging, and protector facies unit A is serially connected with the neutral point N of end box; Protector facies unit B is serially connected with the neutral point N of end box; Protector facies unit C is serially connected with the neutral point N of end box; Protector ground cells D is serially connected with the neutral point N of end box.In other words, the electrode column that is arranged in end box of each functional unit of sectional mo(u)ld overvoltage protection device of the present utility model connects by electrode slice, forms above-mentioned neutral point N.
