Abstract
The utility model discloses a wiring protection device of fixed CT cable, it includes the CT supporting seat, and CT body fixed mounting is provided with cable connecting terminal at the top of CT body on the CT supporting seat, and the electric core of cable is connected on cable connecting terminal, and through a plurality of heat insulating boards of short ribbon fixedly connected with, the heat insulating board passes through long ribbon fixed mounting on the CT body on the cable. This device can conveniently be fixed the cable on the CT body, has effectively completely cut off the heat transfer between cable and the CT body moreover, prevents that its temperature rise is too high, to the harm of cable, can undertake the gravity of cable through termination to avoided droing because of gravity between cable and the CT binding post, prevented also that the CT binding post who leads to because of vibrations from droing, has avoided the problem that CT opened a way and unwanted operation of protection does.
Description
Technical field
The utility model relates to a kind of Wiring protection device, particularly relates to a kind of Wiring protection device of fixation of C T cable.
Background technology
CT be automatically, protection, the professional electric current progress of disease equipment that must use of secondary such as excitation; CT conductive cable contacts is bad is the main cause causing CT to open a way; by producing very high voltage and then easily burning out equipment after operating unit generation CT open circuit, false protection is caused to trip.Existing CT is due to the defect of structural design, and CT binding post is positioned at directly over it, and cable is connected with CT binding post, the gravity bearing cable in junction is larger, easily to come off, and when unit rotate produce vibrations larger time, more easily cause cable and CT binding post to come off.The present the following aspects of concrete defect map.
(1) a lot of CT binding post is positioned at the top of CT now, and the weight of partial cables bears the gravity of cable completely by the line nose on CT binding post; Because cable is heavier, easily make cable come off from line nose, cause open circuit.
(2) in some units' installation process, the cable core that CT cable is transferred to is shorter, makes line nose bear weight larger.
(3) design inconsiderate, do not design the wiring slot way of CT cable, installation unit, in installation process, is directly constructed according to the design drawing of designing institute, does not consider self stressed problem of CT cable.
Utility model content
The purpose of this utility model is to provide a kind of Wiring protection device of fixation of C T cable; cable can conveniently be fixed on CT body by this device; and the heat trnasfer effectively completely cut off between cable and CT body; prevent its temperature rise too high; to the harm of cable, the gravity of cable can be born by termination, thus avoid between cable and CT binding post and come off because of gravity; also prevent the CT binding post caused because of vibrations from coming off, avoid the problem of CT open circuit and protection misoperation.
In order to realize above-mentioned technical characteristic; the purpose of this utility model is achieved in that a kind of Wiring protection device of fixation of C T cable; it comprises CT supporting seat; CT body is fixedly mounted on CT supporting seat; the top of CT body is provided with cable connecting terminal; the battery core of cable is connected on cable connecting terminal, and cable is fixedly connected with multiple thermal insulation board by short band, and thermal insulation board is fixedly mounted on CT body by long band.
Described thermal insulation board is processed with multiple installing hole.
Described thermal insulation board adopts epoxy plate material to make.
The length of described thermal insulation board and width are 60-70mm.
The thickness of described thermal insulation board is 3-7mm.
The utility model has following beneficial effect:
When stube cable, first the battery core of cable is connected with the cable connecting terminal being arranged on CT body top, then reserved certain battery core length, by short band, thermal insulation board is connected on cable, connect at least two thermal insulation boards simultaneously, again thermal insulation board is fixedly connected on CT body by long band, adopt above-mentioned Wiring protection device, cable and CT body can be made effectively to fix, by the weight transfer of cable self to CT body, avoid cable pulling cable connecting terminal, prevent it from coming off, the heat that can effectively prevent CT body from producing by the heat-blocking action of thermal insulation board is delivered to cable, cable is played a protective role, by thermal insulation board, whole cable is fixed on CT body, when preventing CT body that vibrations occur, cause coming off of cable.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the utility model integral installation structural representation.
Fig. 2 is the utility model heat insulation plate structure schematic diagram.
In figure: CT body 1, cable connecting terminal 2, battery core 3, cable 4, thermal insulation board 5, long band 6, installing hole 7, short band 8, CT supporting seat 9.
Embodiment
Below in conjunction with accompanying drawing, execution mode of the present utility model is described further.
As shown in Figure 1-2; a kind of Wiring protection device of fixation of C T cable; it comprises CT supporting seat 9; CT body 1 is fixedly mounted on CT supporting seat 9; the top of CT body 1 is provided with cable connecting terminal 2; the battery core 3 of cable 4 is connected on cable connecting terminal 2, and cable 4 is fixedly connected with multiple thermal insulation board 5 by short band 8, and thermal insulation board 5 is fixedly mounted on CT body 1 by long band 6.Can thermal insulation board 5 be fixed on cable 4 by short band 8, can thermal insulation board 5 be fixed on CT body 1 by long band 6, thus by the force of gravity of cable 4 on thermal insulation board 5, prevent from coming off between battery core 3 and cable connecting terminal 2, and cause open circuit or loose contact.
Further, described thermal insulation board 5 is processed with multiple installing hole 7.Being fixedly connected with between thermal insulation board 5 with cable 4 can be facilitated by installing hole 7.
Further, described thermal insulation board 5 adopts epoxy plate material to make.Adopt epoxy plate material can play effective heat-blocking action, thus prevent the heat produced in CT body 1 course of work to be delivered to cable, harm is produced to cable.
Further, the length of described thermal insulation board 5 and width are 60-70mm.Its size can be determined according to the size of CT body 1.
Further, the thickness of described thermal insulation board 5 is 3-7mm.Its thickness also can be determined by the size of CT body 1.
Operation principle of the present utility model is:
Cable 4 is fixedly mounted on CT body 1 by thermal insulation board 5, thus by the force of gravity of cable 4 on CT body 1, ensure that the reliability that battery core 3 is connected with cable connecting terminal 2, prevent it from coming off, and can avoid the vibration of generator that battery core 3 and cable connecting terminal 2 are come off, improve the fail safe of connection.
