Abstract
The utility model discloses a conjoined contact box which comprises three cylinder bodies and an installing base, wherein the cylinder bodies and the installing base are integrally poured and formed by epoxy resin, the three cylinder bodies are arranged on the installing base in parallel, insulating fixing plates are respectively connected between the cylinder body at the middle and the cylinder bodies at two sides, and notches are formed in one sides of the upper ends of the cylinder bodies. The conjoined contact box is reasonable in structure, convenient to install and high in use safety.
Description
Technical field:
The utility model relates to a kind of high-tension switch cabinet, is specifically a kind of conjuncted contact box.
Background technology:
Contact box is requisite element on handcart type high voltage switch cabinet, and it has the fade function of supporting dynamic/static contact, and the dynamic and static contact of three-phase in the isolating switch cabinet that is used for insulating, and prevents that a series of electricity such as external equipment discharges such as dynamic and static contact and cabinet from reacting.After using contact box, the installation of circuit and maintenance are all very convenient, and the quality of contact box quality will be directly connected to the insulation property of whole switch cubicle and the reliability of safe operation.existing contact box is that 3 single-phase contact boxs arrangements assemble substantially, single-phase contact box adopts mixture of epoxy resins injection moulding, the contact box box wall that this processing technology is made is thinner, structural strength is relatively low, if being arranged, 3 single-phase contact boxs fit together, the one side complex installation process, also need to consider the problem of temperature rise that the electromagnetic eddy that produces on single-phase contact box mounting plate causes during installation, if the air distance is unreasonable, easily produce the accidents such as burning, the location is also more difficult on the other hand, and the seam crossing of contact box often leaves the gap, can affect globality and the insulation property of switch cubicle.
The utility model content:
Technical problem to be solved in the utility model is to provide a kind of rational in infrastructure, easy for installation, conjuncted contact box safe to use.
Technical solution of the present utility model is, a kind of conjuncted contact box is provided, comprise three cylindrical shells and a mounting seat, cylindrical shell and mounting seat are epoxy resin one moulding by casting, three cylindrical shells are set in parallel on mounting seat, be connected with respectively insulation fixing plate between middle cylindrical shell and the cylindrical shell of both sides, described cylindrical shell upper end one side is provided with gap.
Adopt after above structure compared with prior art, the utlity model has following advantage: because three cylindrical shells and mounting seat are epoxy resin one moulding by casting, and cylindrical shell is set in parallel on mounting seat, install and constantly be directly installed on the heel post of switch cubicle, and needn't adjust position between cylindrical shell, need not go to determine the air distance, fail safe has obtained raising again; And be connected with respectively insulation fixing plate between the cylindrical shell of the cylindrical shell of centre and both sides, and the distance between can fixed cylinder, point value is put in the part of reducing product, and cylindrical shell upper end one side is provided with gap, can play the effect of heat radiation.
As preferably, be provided with stiffener between described cylindrical shell and mounting seat.
Further, described insulation fixing plate fixed head is positioned at position, lower middle, the cylindrical shell outside.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is upward view of the present utility model.
In figure, 1, cylindrical shell, 2, mounting seat, 3, insulation fixing plate, 4, stiffener.
Embodiment:
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
As shown in Figure 1 and Figure 2, a kind of conjuncted contact box, comprise three cylindrical shells 1 and a mounting seat 2, cylindrical shell 1 and mounting seat 2 are epoxy resin one moulding by casting, three cylindrical shells 1 are set in parallel on mounting seat 2, are connected with respectively insulation fixing plate 3 between middle cylindrical shell 2 and the cylindrical shell 2 of both sides, and described insulation fixing plate 3 is positioned at cylindrical shell 1 position, lower middle, the outside, described cylindrical shell 1 upper end one side is provided with gap, is provided with stiffener 4 between described cylindrical shell and 1 mounting seat 2.
Below only be described with regard to the utility model preferred embodiment, but can not be interpreted as it is limitations on claims.Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do includes within scope of patent protection of the present utility model.
