Abstract
Secondary cable protection cover in high tension switchgear secondary cable door, its characterized in that are equipped with square frame and protection network, and the peripheral interior periphery with the frame of protection network is connected, one side of frame be equipped with with frame looks vertically landing leg, be equipped with connect the via hole on landing leg and the support, regional relatively fixed that the interior secondary line of high tension switchgear door was arranged, thereby can guarantee the size of frame is fixed, according to spatial layout in the cabinet door, adopt the PVC plastic slab of high strength to be processed into suitable square shape, the cover is realized physics and is kept apart in the secondary wiring, through design the installation that realizes the protection network in a strip groove in the frame, because the protection network has good air permeability, realize electric component's effectual heat dissipation to a possibility of interior secondary line is bumped to the mistake in the work of stopping, and fundamentally guarantees the security of operation, the further emergence of avoid accident, and the security performance is good.
Description
Technical field
The utility model relates to power supply unit, specifically secondary cable protective cover in a kind of high-tension switch cabinet secondary cable door improving security performance.
Background technology
We know, the equal unprotect cover of secondary cable in the high-tension switch cabinet secondary cable door that present substation uses, open cabinet outside secondary cable is directly exposed to behind the door, daily tour, often to open this cabinet door in the work such as maintenance and carry out related work, carry out in work at unlatching cabinet door, because activity space is little, easily touch secondary line by mistake, the generation caused the accident, therefore present usual way has special messenger to guard, but this can not tackle the problem at its root, even if special messenger guards, operating personnel also casually can touch the secondary cable in switch cubicle secondary cable door often, long-term touching probably causes loosening of binding post, cause equipment operation exception, give the person, electrical network, the safety of equipment brings huge hidden danger.
Summary of the invention
The purpose of this utility model overcomes above-mentioned the deficiencies in the prior art, provides easy for installation, security performance is good, secondary cable protective cover in the high-tension switch cabinet secondary cable door of handled easily.
The utility model can be reached by following measure:
Secondary cable protective cover in high-tension switch cabinet secondary cable door; it is characterized in that being provided with quadra and protection network; the periphery of protection network is connected with the inner rim of framework, and the side of framework is provided with the supporting leg perpendicular with framework, and supporting leg and support are provided with connecting through hole.
Supporting leg described in the utility model is hollow bar, and hollow bar one end is connected with framework is vertical, and framework is provided with and hollow bar coaxial line, isodiametric through hole, to facilitate the connection with cabinet door.
Described in the utility model leg length is 4-8cm, and supporting leg is separately positioned on four corners of framework, to facilitate the connection with cabinet door.
Protection network described in the utility model is PVC Holland net, to improve its fail safe and thermal diffusivity.
The region that in high-voltage switch cabinet door described in the utility model, secondary line is arranged is relatively fixing, thus can ensure that the size of described framework is fixed; According to space layout in cabinet door, adopt the PVC plastic flitch of high strength to be processed into suitable square configuration, cover in secondary wiring, realize physical isolation; By designing the installation that a strip slot realizes protection network in framework, because protection network has good air permeability, realize the effective heat radiation of electricity piece, thus stop the possibility of by mistake touching secondary line in door in work, fundamentally ensure the fail safe of operation, its beneficial effect: (1) PVC plastic cost is low, is convenient to promote; (2) processing technology is ripe, is beneficial to realization; (3) PVC material resistance to chemical attack is good insulator, and lightweight and firm; (4) this invention effectively can realize effective isolation of secondary line and operating personnel, the generation of further Accident prevention, and security performance is good.
Accompanying drawing explanation
Fig. 1 a kind of structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Secondary cable protective cover in high-tension switch cabinet secondary cable door, it is characterized in that being provided with quadra 1 and protection network 2, the periphery of protection network 2 is connected with the inner rim of framework 1, the side of framework 1 is provided with the supporting leg 3 perpendicular with framework 1, supporting leg 3 and support are provided with connecting through hole, supporting leg 3 is hollow bar, hollow bar one end is connected with framework 1 is vertical, framework 1 is provided with and hollow bar coaxial line, isodiametric through hole, to facilitate the connection with cabinet door, supporting leg 3 length is 4-8cm, supporting leg 3 is separately positioned on four corners of framework 1, to facilitate the connection with cabinet door, protection network is PVC Holland net, to improve its fail safe and thermal diffusivity, the region that in high-voltage switch cabinet door, secondary line is arranged is relatively fixing, thus can ensure that the size of described framework is fixed, according to space layout in cabinet door, the PVC plastic flitch of high strength is adopted to be processed into suitable square configuration, cover in secondary wiring, realize physical isolation, by designing the installation that a strip slot realizes protection network in framework, because protection network has good air permeability, realize the effective heat radiation of electricity piece, thus stop the possibility of by mistake touching secondary line in door in work, fundamentally ensure the fail safe of operation, its beneficial effect: (1) PVC plastic cost is low, is convenient to promote, (2) processing technology is ripe, is beneficial to realization, (3) PVC material resistance to chemical attack is good insulator, and lightweight and firm, (4) this invention effectively can realize effective isolation of secondary line and operating personnel, the generation of further Accident prevention, and security performance is good.
