Abstract
The utility model provides an explosion-proof case for an intermediate connector, which comprises the intermediate connector, a flame-retardant belt, fire retardant, a sealing ring, filling glue, the explosion-proof case and a glue-pouring perforated cover. The flame-retardant belt is wound around the surface of the intermediate connector, the surface of the intermediate connector which is wound by the flame-retardant belt is coated with a fire retardant layer, the intermediate connector is arranged in the explosion-proof case, the sealing ring is arranged in a seal groove, the filling glue is filled into two ends of the explosion-proof case, the glue pouring perforated cover is arranged on the explosion-proof case, and the sealing glue enters the explosion-proof case via the glue pouring perforated cover. The explosion-proof case is made of SMC (Sheet Molding Compound) material, thereby overcoming the disadvantage of heaviness of a metal case, and having the advantages including electrostatic prevention, high intensity and convenience in installation and maintenance; the case is equipped with a pressure release port, so that impact force after buffering can be released via the pressure release port, and explosion force is reduced to the minimum; and the surface of the connector is coated with the expansion type fire retardant, wherein when the temperature reaches 150 DEG C, the fire retardant is expanded to isolate the air which is required by combustion and rapidly extinguishes the flame.
Description
Technical field
The utility model relates to the urban power distribution network transition joint, relates in particular to the transition joint explosion-proof shell.
Background technology
Existing transition joint sheathing material adopts the metals such as spheroidal graphite cast-iron;
Enclosure interior is filled with quartz sand, the impulsive force of utilizing the blast of quartz sand buffering to produce.
There is no special waterproof sealing means.
Problem and the defect of its existence are:
Metal product heaviness, be not easy to installation and maintenance, for a long time for the wet environment corrosion-vulnerable, get rusty;
Do not have in the situation of special pressure release passage, with quartz sand, fill and not only can not cushion the power that blast produces, also can make power strengthen.
At the environment of underground humidity, if there is no the waterproof sealing measure, will greatly shorten transition joint useful life.
The utility model content
In order to solve problem in prior art, the utility model provides a kind of transition joint explosion-proof shell, it comprises transition joint, inhibiting tape, fire retardant, sealing ring, filling glue, explosion-proof shell, encapsulating port lid, the transition joint surface is wound around inhibiting tape, the transition joint surface that is wound around inhibiting tape is coated with one deck fire retardant, transition joint is arranged in explosion-proof shell, sealing ring is arranged on seal groove, fill glue and be filled in the explosion-proof shell two ends, the encapsulating port lid is arranged on explosion-proof shell, and fluid sealant is poured in explosion-proof shell by the encapsulating port lid.
As further improvement of the utility model, described fire retardant is expansion type flame retardant IFR.IFR, be a kind of composite flame-retardant agent that nitrogen, phosphorus is chief component of take, and it is not halogen-containing, does not adopt antimony oxide as synergist yet, and this based flame retardant foaming and intumescing when being heated, therefore be called expansion type flame retardant.
As further improvement of the utility model, the housing that described explosion-proof shell is two docking, locked the housing of the explosion-proof shell of two docking by screw.
As further improvement of the utility model, also comprise pressure relief opening, described pressure relief opening is arranged on explosion-proof shell.
The beneficial effects of the utility model are:
This new type explosion proof shell adopts the SMC(sheet molding compound) material, overcome the shortcoming of metal shell heaviness, have that antistatic, intensity are high, the advantage such as be easy for installation and maintenance;
Housing carries pressure relief opening, and the impulsive force after buffering can, from the pressure relief opening pressure release, drop to brisance minimum.
Joint surface is smeared expansion type flame retardant, when temperature reaches 150 ℃, and fire retardant meeting foaming and intumescing, the needed air of isolated burning, knock down the flame rapidly.
SMC housing Heat stability is good, corrosion-resistant, sealed by sealing ring, fluid sealant etc., and good seal performance is non-maintaining.
The accompanying drawing explanation
Fig. 1 is the utility model transition joint explosion-proof shell structural representation;
Fig. 2 to Fig. 6 is the utility model transition joint explosion-proof shell scheme of installation.
In figure, each component names is as follows:
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.

A kind of transition joint explosion-proof shell, it comprises transition joint 1, inhibiting tape 2, fire retardant 3, sealing ring 6, fills glue 7, explosion-proof shell 20, encapsulating port lid 30, also comprises pressure relief opening 8, and described pressure relief opening is arranged on explosion-proof shell;
The transition joint surface is wound around inhibiting tape, the transition joint surface that is wound around inhibiting tape is coated with one deck fire retardant, transition joint is arranged in explosion-proof shell, sealing ring is arranged on seal groove, fill glue and be filled in the explosion-proof shell two ends, the encapsulating port lid is arranged on explosion-proof shell, and fluid sealant is poured in explosion-proof shell by the encapsulating port lid.Described fire retardant is expansion type flame retardant IFR.The housing that described explosion-proof shell is two docking, locked the housing of the explosion-proof shell of two docking by screw.
Installation procedure:
Be wound around inhibiting tape on the transition joint surface, as shown in Figure 2.
After being wound around inhibiting tape, be coated with one deck expansion type flame retardant IFR on surface, as shown in Figure 3.
By being wound around inhibiting tape, the cable that is painted with IFR puts into explosion-proof shell 20, then sealing ring put into to seal groove, with screw, explosion-proof shell is locked, as shown in Figure 4.
With filling glue, the explosion-proof shell two ends are filled, then raise the encapsulating port lid, pour into the A/B fluid sealant, as shown in Figure 5.
After pouring into the A/B fluid sealant, cover encapsulating port lid 30, complete the transition joint explosion-proof shell and install, after completing as shown in Figure 6.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
