The utility model content
Shortcomings such as installing/dismounting inconvenience, the creepage distance that exists at metal-clad moveable formula contact box for switch cabinet in the prior art is little, the technical problems to be solved in the utility model provide a kind of easy for installation, mechanical strength is high, creepage distance is big metal-clad moveable formula contact box for switch cabinet.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
Comprising by an inlet wire fixed contact, an inlet wire sleeve, outlet terminal row, high-voltage terminal insulating cover and an insulating mounting dividing plate adopts the epoxide resin vacuum cast to form integral structure; The cross section of insulating mounting dividing plate is the right angle folding shape, and both sides are provided with the step seam with the function of being sealed and matched.
The main part of insulating mounting dividing plate is vertically through an inlet wire sleeve, and two sides are provided with the reinforcement gusset on axis; An inlet wire fixed contact and an outlet terminal row are the one form, whole bottom of adopting bolted at an inlet wire sleeve; The uncovered end face front view cross section of described high-voltage terminal insulating cover is the right angle form, and the vertical view cross section is flat U-shaped structure, and side view section is a U-shaped structure at the bottom of the semicircle, and the place, diagonal angle of the uncovered end face of U-shaped structure is the round-corner transition form at the bottom of the semicircle; Inlet wire sleeve peripheral end and root are provided with uniform full skirt; Described right angle folding is the round-corner transition form.
The utlity model has following beneficial effect and advantage:
1. mechanical strength height, easy for installation: the utility model is whole, and to adopt the cross section be right angle folding shape insulating mounting dividing plate and step seam fit system, realize installing, and guaranteed that product has higher mechanical strength in use and transportation with the convenient of cabinet.
2. insulation is stable, creepage distance is big: reliable insulation full skirt has been designed in entrance bushing peripheral end of the utility model high pressure and root position, and utilize its insulating mounting dividing plate that carries to install, further strengthened the utility model surface creepage distance, it is more stable to insulate.
3. interchangeability is good, versatility is high: the utility model is installed and used in the process need not distinguish the product phase sequence, exchange can arbitrarily be installed, an inlet wire fixed contact and an outlet terminal row's one form, adopt the bottom of bolted at an inlet wire sleeve, its version can design change arbitrarily according to user and design needs, need applicable to the form of ownership switch cubicle, thereby improved standardization, generalization that switchgear is processed.

Embodiment
Shown in Fig. 1～4, the utility model metal-clad moveable formula contact box for switch cabinet comprises by inlet wire fixed contact 1, inlet wire sleeve 2, outlet terminal row 3, high-voltage terminal insulating cover 4, insulating mounting dividing plate 5, adopts the epoxide resin vacuum cast to form integral structure; The cross section of insulating mounting dividing plate 5 is the right angle folding shape of the excessive form of fillet, and both sides are provided with the step seam 6 with the function of being sealed and matched.
The main body of insulating mounting dividing plate 5 distributes vertically through an inlet wire sleeve 2, and two sides are provided with reinforcement gusset 7 on axis; An inlet wire fixed contact 1 and an outlet terminal row 3 are the one form, whole bottom of adopting bolted at an inlet wire sleeve 2; The uncovered end face front view cross section of described high-voltage terminal insulating cover 4 is the right angle form, and the vertical view cross section is flat U-shaped structure, and side view section is a U-shaped structure at the bottom of the semicircle, and the place, diagonal angle of uncovered end face is fillet 8 interim forms; Inlet wire sleeve 2 peripheral end and root are provided with uniform full skirt 9.
The utility model is when assembling, accordingly make up fixing according to specification requirement mould, adopt the epoxide resin vacuum cast after solidifying, to form, become a integral structure thereupon by inlet wire sleeve 2, high-voltage terminal insulating cover 4, insulating mounting dividing plate 5; Insulating mounting dividing plate 5 (is for the right angle folding shape
Shape), and the sidepiece design has the step seam 6 of sealing function, use and directly to utilize insulating mounting dividing plate 5 to realize installing smoothly when installing, and the step seam that utilizes sidepiece realizes mutual being sealed and matched that the utility model three is alternate, makes the isolation of effectively insulating of cabinet high voltage bus chamber and other parts; The main part of insulating mounting dividing plate 5 is vertically through an inlet wire sleeve 2, and two sides are equipped with and strengthen gusset 7 on axis, avoid the utility model install and use and the integral device transportation in damage because stress is concentrated, further strengthen mechanical strength of the present utility model; The uncovered end face front view cross section of high-voltage terminal insulating cover is the right angle form, the vertical view cross section is flat U-shaped structure, side view section is a U-shaped structure at the bottom of the semicircle, the place, diagonal angle of uncovered end face is fillet 8 interim forms, the operating space that connects with the cabinet bus as contact box, strengthen alternate insulation level effectively, reduced most advanced and sophisticated electric field; Inlet wire sleeve 2 peripheral end and root design have uniform full skirt 9, effectively increase the product surface creepage distance.
