Abstract
The utility model discloses a cross interconnection box for the high-voltage single-core electric force cable, including a box body(1) and a shielding protector(2). The box body(1) is made of the stainless steel or the aluminum alloy, and an inlet cable(6) is connected with the shielding protector(2) in an insertion-pull structure through a plug(3), and a socket(8). An insulating material injects the socket(8) and the box body(1), and the place between the inlet cable(6) and the box body(1) is coated with a sealing sleeve(4) and a wire intake sleeve(5). The utility model mainly used for the interconnection of the metal sheaths for the high-voltage single-core electric force cables and the cross interconnection box for the high-voltage single-core electric force cable is a waterproof, dampproof and fireproof injection type cross interconnection device for the high-voltage single-core electric force cable, with the volume small, the weight light and the assembly convenient.
Description
Technical field
The utility model relates to a kind of cross interconnected case, particularly relates to the cross interconnected case of a kind of high pressure single-core power cables.
Background technology
Along with the develop rapidly of Chinese national economy, electricity needs is constantly soaring.The construction development of high-power electric transmission network is very rapid, and the high pressure single-core power cables uses very generally.Induced voltage for control power cable metal sheath reduces or eliminates the ring current on the sheath, improves the transmission capacity of cable, prevents that protective coverings of cable from puncturing, and guarantees the safe operation of cable.At present, the cross interconnected case on the market, volume is all bigger, and weight is heavier; Water resistance does not reach the requirement of prevention waterlogging; The inlet wire structure generally adopts the bolt compression joint type, and the inlet wire port sealing adopts modes such as wrapped band, and does not separate sheath protector end and end of incoming cables, and waterproof and dampproof performance is poor, installs more numerous and diverse; Casing adopts modes such as steel plate welding, and there are hidden danger in waterproof and insulation property.During installation, case lid must be opened and could connect earth connection, so poor sealing performance is installed very trouble.
The utility model content
Technical problem to be solved in the utility model provides that a kind of volume is less, and weight is lighter, and waterproof and dampproof fire protecting performance is better, the cross interconnected case of high pressure single-core power cables easy for installation.
In order to solve the problems of the technologies described above; the cross interconnected case of high pressure single-core power cables that the utility model provides; comprise casing and sheath protector; described casing is made by stainless steel or aluminium alloy; the inlet wire cable adopts the plug-in wiring construction by connect-disconnect plug and plug seat thereof with described sheath protector; insulating material pours into an integrated entity described plug seat with described casing, be set with sealing shroud and inlet wire cover between described inlet wire cable and described casing.
Described sealing shroud is a cone-shaped sealed gland.
Described inlet wire cable is the ground insulation power cable of coaxial cable or three-phase six line formulas.
Adopt the cross interconnected case of high pressure single-core power cables of technique scheme, casing is poured into an integrated entity by stainless steel or aluminium alloy and insulating material, has good waterproof performance, little, in light weight, the good insulation preformance of volume; Sheath protector adopts the ZnO varistor protection component and insulating material is compound makes, and has good voltage-current characteristic and sealing property; Inlet wire cable and sheath protector adopt connect-disconnect plug and plug seat plug-in wiring construction thereof, have characteristics quick and easy for installation; Cone-shaped sealed gland adopts that rubber is prefabricated to form, have good springiness, characteristics such as ageing-resistant, waterproof and dampproof, safe and reliable, easy for installation, both save the wrapped material that set-up time and waterproof are used, and can effectively solve the waterproof and dampproof problem of product again, improved the reliability of installing.Casting insulated material is separated end of incoming cables and sheath protector, has solved the water resistance of product well, can effectively reduce small product size and weight, makes to install to become very convenient, fast, need not to open case lid again.The used inlet wire cable of this structure adopts coaxial power cable or three-phase six line formula ground insulation power cables.The utility model is mainly used in the cross interconnected of high pressure single-core power cables metallic sheath, the rising of restriction sheath and insulating joint insulating segment both sides impulse overvoltage, the induced voltage of control metallic sheath, reduce or eliminate the ring current on the sheath, improve the transmission capacity of cable, prevent that protective coverings of cable from puncturing, and guarantees the safe operation of cable.
In sum, the utility model is that a kind of volume is less, and weight is lighter, and waterproof and dampproof fire protecting performance is better, the cross interconnected case of high pressure single-core power cables easy for installation.
