Closed using fire resisting anti-explosion groove box.13.2.2.1 the in-service joint of cable close quarters should install fire prevention channel box additional or take other to prevent
Fiery quarantine measures.
Because cable intermediate joint is cable most weak link, it is of equal importance with cable.With China's national economy
High speed development, Chinese cableization popularizes engineering throughout each city, and cable is focused on electricity by increasing cable chemical industry journey
In cable ditch or cable shaft, the cable intermediate joint of cable shaft or cable duct in power grid construction is provided by the cableization of national grid
It is not allow side by side, but due to existing in many objectively factor cables among urban distribution network cable chemical industry journey of today
Between the situation of joint side by side seem to avoid, and common cable intermediate joint be often three or so it is even more simultaneously
Row；The cable duct cable outlet of transformer station is often more than ten or more.With the popularization of power cable chemical industry journey, cable thing
Therefore rate also increases therewith, a host of facts are proved, most cable fault is relevant with cable accessory, particularly in cable indirectly
Head.Due to quality and mounting process, cable intermediate joint once explodes, gently other cables then same ditch side by side
Also destroy, serious will lead to cable fire, and irremediable loss is caused to whole power system.
Current cable intermediate joint safety box only protects cable connector by cable connector safety box shell, internal
There is no other protection devices, occur explosion time produce power just cannot preferably protect greatly, and at safety box necking compared with
For weakness, occur explosion time energy in cable and easily sprayed at necking, the facility of surrounding is caused to damage.
Utility model content
The purpose of this utility model is to provide the cable intermediate joint safety box for filling fire-proof mud in a kind of inside, to solve
The current cable intermediate joint safety box proposed in above-mentioned background technology is only protected by cable connector safety box shell
Cable connector, inside just cannot preferably be protected greatly without other protection devices in the power for occurring explosion time generation, and peace
It is more weak at full box necking, occur explosion time energy in cable and easily sprayed at necking, that damages is caused to the facility of surrounding
Problem.
To achieve the above object, the utility model provides following technical scheme：Fill in the cable of fire-proof mud a kind of inside
Between joint safety box, including upper shell, lower house, explosion-proof hexagon socket head cap screw, pre-buried explosion-proof relief point, sealing strip, groove, reinforcement

It is threadedly coupled, and upper shell and lower house junction are provided with sealing strip, the upper shell and are provided with pre-buried explosion-proof relief point, institute
Inwall at upper shell and the necking of lower house two ends is stated provided with there is therewith mutually chimeric waterproof washer in groove, and groove, it is described on
Housing and lower house collectively constitute protection shell, and the protection enclosure is provided between inner casing, and inner casing and protection shell and set
There is anti-flaming thermal-insulation layer, the inner housing inner fills outside at fire-proof mud, upper shell and the lower house necking and is provided with reinforcement
Muscle.
It is preferred that, the upper shell and lower house are two ends necking ship type structure broad in the middle, and outside at the necking of two ends
It is provided with reinforcement.
It is preferred that, the anti-flaming thermal-insulation layer is ceramic fibre material.
It is preferred that, the pre-buried explosion-proof relief point is offered everywhere altogether.
It is preferred that, the thickness of the inner casing is more than the thickness of upper shell and lower house.
Compared with prior art, the beneficial effects of the utility model are：The cable intermediate joint of fire-proof mud is filled inside this
Safety box uses two ends necking ship type structure broad in the middle, and outside is provided with reinforcement at the necking of two ends, is not increasing necking
Locate under conditions of thickness, intensity and rigidity at enhancing necking allow necking to be in cable generation explosion time and withstood shocks, keeps away
Exempt from explosion energy ejection the cable of surrounding is caused to damage, the cable intermediate joint safety box increases inner casing in the inside of shell,
Double shielding effect is reached, and inner housing inner fills fire-proof mud, available for the holes blocking of cable, cable can be prevented in generation
Spread during fire from hole to adjacent room, reduce fire produce property loss, it is to avoid the expansion of accident, and with resistance cigarette, fire prevention,
The function such as dust-proof, the thickness of inner casing is more than the thickness of shell, because inner casing is the first explosion-proof layer, is subjected to most impact
Power, the thickness of increase inner casing helps to strengthen the explosion-proof capabilities of inner casing, it is born from internal superpower impact.
