Description
Technical field
Cable grounding technical field is the utility model is related to, more particularly to a kind of separate type protection type earthing box for electric cable.
Background technology
In power system, earthing box for electric cable is the visual plant for ensureing cable safe and stable operation, when cable core is sent out
When raw earth fault, lightning wave or internal overvoltage, very high voltage can be produced on cable metal sheath.When in earthing box for electric cable
When cable metal sheath is grounded via protector, protector surface easily turns into the passage that electric arc occurs, under arcing, protection
Device easily bursts, and the air themperature rise in grounding box, pressure increase, causes to explode in case；There is no pressure release in casing
Passage, if now positive someone works before grounding box, very likely the person is caused to seriously endanger；In addition, it is existing
Space is too small between the cross interconnected connecting plate of conventional panel shape, causes great inconvenience to test, or even can not complete.
Utility model content
The purpose of this utility model is to provide a kind of separate type protection type earthing box for electric cable.
Therefore, technical solutions of the utility model are as follows：
A kind of separate type protection type earthing box for electric cable, including casing, protector and cross interconnected plate, protector and intersection are mutual
Yoke plate is arranged in casing, and coaxial cable is connected to protector by cross interconnected plate and connecting plate, and cross interconnected plate includes
Two short-circuit boards be arrangeding in parallel and the long fishplate bar with two short-circuit board cross-fixings, described casing are separated into protector room
With cross interconnected room, and through hole is formed on division surface；Protector and cross interconnected plate are separately positioned on protector room and intersection
Interconnection is indoor, and connecting plate links together protector and cross interconnected plate through the through hole on division surface, and through hole ensure that company
Fishplate bar passes through but keeps closure, and described short-circuit board is domes, is equipped with described protector room and cross interconnected room
Chamber door.
Preferably, pressure release plug is equipped with two sides of described protector room.
Preferably, the chamber door of described protector room and cross interconnected room may be detachably retained at protector room and
On cross interconnected room.
Compared with prior art, the separate type protection type earthing box for electric cable realizes point of protector and cross-connect plate
From, Isolation protector and operating personnel's working space, the protection to operating personnel have effectively achieved；At the same time, intersect mutual
The domes of yoke plate are convenient for on-the-spot test.

Embodiment
Below in conjunction with the accompanying drawings and specific embodiment is described further to the utility model, but following embodiments are right absolutely not
The utility model has any restrictions.
As Figure 1-3, the separate type protection type earthing box for electric cable, including casing, protector 1 and cross interconnected plate 2, protect
Shield device 1 and cross interconnected plate 2 are arranged in casing, and coaxial cable is connected to protector by cross interconnected plate 2 and connecting plate
1, at the same time, protector 1 is connected to earthing pole 7, cross interconnected plate 2 include two short-circuit boards 5 be arrangeding in parallel and with two
The long fishplate bar 6 of the cross-fixing of short-circuit board 5, described casing are separated into protector room 3 and cross interconnected room 4, and in division surface
Upper formation through hole；Protector 1 and cross interconnected plate 2 are separately positioned in protector room 3 and cross interconnected room 4, and connecting plate passes through
Through hole on division surface links together protector 1 and cross interconnected plate 2, and via design ensures into being only capable of by connecting plate
Protector room 3 and the respective sealing of cross interconnected room 4, pressure release plug 8 is equipped with two sides of protector room 3, when
Temperature rise in protector room 3, when pressure increases, pressure release plug 8 can in time be rushed out and discharge internal pressure, described
Short-circuit board 5 be domes, make to form certain space between short-circuit board 5 and long fishplate bar 6, personnel easy to operation utilize annular
Current transformer is tested ring current；It is equipped with to utilize on protector room 3 and cross interconnected room 4 and is bolted to protection
Chamber door on device room 3 and cross interconnected room 4；When carrying out routine experimentation and breakdown repair, staff only passes through demounting bolt
Can realizes the dismounting to protector room 3 and the chamber door of cross interconnected room 4, drastically increases operating efficiency.
