Further, in the present embodiment, cover board 13 is installed on the one end of cable 3 far from mounting base 2；Also, it covers
Grading shield 14 is installed outside plate 13.The cover board 13 and grading shield 14 are mainly used for the electric field inside control and uniform device so that
The safety coefficient higher of cable accessory and terminal, whole equipment are capable of the operation of more steady safety.
Further, in the present embodiment, outlet rod 15, outlet rod are installed on the one end of cable 3 far from mounting base 2
15 are pierced by grading shield 14.
In conclusion the cable accessory obtained by above-mentioned design, the cable accessory is due to high with above-mentioned explosion-proof type
Voltage cable outdoor terminal 1, by pressure guiding cover 6 and pressure release ring 5 that the power guiding for explosion of breaking down is downward
Mode, so that the failure mechanics of terminal are contracted to the range that can be controlled, to avoid the loss of people's property, to more square
Just, quick and be effectively protected electric system.Wherein, explosion-proof type high-voltage cable outdoor terminal 1 comprising mounting base 2, electricity
Cable 3, barrel support 4, pressure release ring 5, pressure guiding cover 6 and casing 7；Since barrel support 4 is mounted on mounting base 2, pressure
On barrel support 4, pressure guiding cover 6 covers on barrel support 4 power release ring 5, the opening direction direction peace of pressure guiding cover 6
Fill bottom plate 2；Therefore, the internal pressure of bearing of pressure release ring 5 bears internal pressure less than casing 7, while can ensure that cable 3 is whole nearby
The external and internal pressure of body normal operating condition, and the ejecta guiding that when pressure guiding cover 6 is by terminal fault generates is downward, with this
Cause explosion to injure periphery personnel and equipment preventing terminal fault itself internal pressure, causes the heavy losses of property.Simultaneously as
Casing 7 is set on the outer wall of cable 3, and filling insulating oil is loaded with inside casing 7, multiple pillars are equipped on mounting base 2
Insulator 8, and since the cable accessory of this type of current power transmission system is all in personnel's residential intensive area, and the type
The brisance that the cable accessory of type breaks down is huge；Therefore, event will occur for pressure guiding cover 6 and pressure release ring 5
The power guiding of barrier explosion is downward, so that its failure mechanics is contracted to the range that can be controlled, to avoid the loss of people's property, separately
Outside, the support insulator 8 and casing 7 make the insulation effect of cable 3 more preferable, under the over-voltage conditions such as lightning stroke, operation, cable
The insulation safety of attachment terminal can be guaranteed, operational reliability higher.In addition, stress cone 12 is set in cable 3 close to peace
On the one end for filling bottom plate 2, grading shield 14 is installed outside cover board 13, therefore, stress cone 12 and grading shield 14 can be controlled further
The electric field of system and uniform terminal inner so that the security performance of terminal is further improved, and whole equipment can more be put down
The operation of steady safety.
