Description
Technical field
The utility model relates to a kind of rack of electric power system on-line monitoring, refers to the rack of the on-Line Monitor Device of capacitive apparatus such as a kind of transformer/reactor sleeve pipe that is arranged in power stations such as high pressure, ultra high voltage, current transformer, capacitance type potential transformer, coupling capacitor and lightning arrester especially.
Background technology
Along with the continuous development of voltage class of electric power system, capacity, the electric power system key equipment is more and more, and it is complicated and changeable more and more to seem.Capacitive apparatus, lightning arrester etc. are as equipment important in the electric power system; quantity is many; it is wide to distribute; bearing voltage transformation and power distribution, raising power supplying efficiency; effects such as protection thunderstorm hour power supply safety; but owing to various capacitive apparatus, lightning arrester are in operation various faults may take place, thereby influence safe operation of power system and power supply reliability, we must carry out quick diagnosis and get rid of its fault producing to various faults.But because of capacitive apparatus, lightning arrester all is mounted in outdoor, monitoring device just need be placed in the equipment under test next door (in case the transducer connecting line is oversize so, signal attenuation, measuring accuracy reduces or the like), Ce Shi transducer is more in addition, for example: the transducer of monitoring capacitive apparatus operation conditions, the transducer of monitoring lightning arrester operation conditions etc., a monitoring project again, just need one or several monitoring device and data communications equipment, these all need a safe and reliable rack reliable and secure being arranged in the rack rationally such as monitoring device and data communications equipment.
The utility model content
At the problem that prior art exists, the purpose of this utility model is to provide a kind of space that effectively utilizes, and optical cable is not flexural loading or the stressed rack that is used for the electric power system on-Line Monitor Device less after installation.
For achieving the above object, the rack that is used for electric power system capacitive apparatus and lightning arrester on-line monitoring of the present utility model, comprise cabinet, the base plate of bottom of cabinet bulk is provided with the optical cable line inlet port, and the top of described optical cable line inlet port is provided with the fixed board that is used to install optical fiber terminal box and fibre optic modem; Described fixed board top is provided with the installation position of on-Line Monitor Device; Both sides are respectively arranged with binding post in the rack.
Further, both sides also are provided with trough in the described rack.
Further, described rack inner bottom part also is provided with thermoregulator.
Further, but the back side of described rack has the back door of a folding, and the bottom at this back door is provided with air intake and filters fan; The top of described rack is provided with the air outlet filter.
Further, place, described installation position is provided with the bracing frame of on-Line Monitor Device, and the cabinet of described on-Line Monitor Device is fixed on described fixed board top by support frame as described above.
Optical fiber terminal box and fibre optic modem are by the vertical placement of fixed board in the rack of the present utility model, effectively utilized the space in the rack, and optical fiber terminal box and fibre optic modem are aimed at the optical cable line inlet port on the cabinet base plate, optical cable access rack can not be subjected to or few stress by bending, effectively avoids optical cable because the crooked damage that causes.Because inlet and outlet is provided with filter, the front and back door is provided with sealing joint strip, can guarantee that rack satisfies the requirement of shelter of IP55 simultaneously.
Description of drawings
Fig. 1 is the stereogram under visual angle of rack of the present utility model;
Fig. 2 is the stereogram under another visual angle of rack of the present utility model.
Embodiment
As illustrated in fig. 1 and 2, rack of the present utility model, comprise cabinet 1, the base plate 11 of bottom of cabinet bulk is provided with optical cable line inlet port 2, the top of optical cable line inlet port 2 is provided with the fixed board 3 that is used to install optical fiber terminal box 31 and fibre optic modem 32, optical cable line inlet port 2 is aimed in the vertical placement of optical fiber terminal box 31 and fibre optic modem, the optical cable of access directly vertically is connected with fibre optic modem 32 with optical fiber terminal box 31, prevent to insert the stressed bending of optical cable, cause optical cable to damage, cause the on-line monitoring monitoring of equipment, the data that processing obtains can't transfer to long-range Surveillance center by optical fiber terminal box 31 and fibre optic modem 32; Both sides are respectively arranged with binding post 4 in the cabinet 1, be outside equipped with and gather the interface that the transducer of transformer with power equipment parameters such as reactors is connected at rack, it links to each other with binding post 4 inputs, the output of binding post 4 is connected by equipment such as the capacitive apparatus in connecting line and the cabinet 1 and lightning arrester on-Line Monitor Device, for line attractive in appearance, simple, binding post 4 places of rack both sides also are provided with trough, above-mentioned connecting line all is arranged in the trough, and the trough one of both sides sidles light current, opposite side is walked forceful electric power.Above-mentioned on-line monitoring equipment is fixedly mounted on the top of fixed board 3 by bracing frame 6, and the fixed structure of on-line monitoring equipment can 19 inches structurally-fixed modes of selection standard (5*4U+1*2U), makes the tester marshalling, standardization.But the back side of rack has the back door 12 of a folding, the bottom at this back door 12 is provided with the air intake that is used for air intake and filters fan 13, the top of rack is provided with the air outlet filter (not shown) that is used for air-out, make and produce very little malleation in the rack, help preventing that the rack slit from entering dust, the air-out filter at top prevents that dust enters because of fan stops.Cabinet 1 bottom is provided with the thermoregulator 14 that is used to regulate the cabinet internal temperature.Cabinet 1 adopts all steel material, and appearance is plastic-blasting again, and outdoor corrosion resistance is stronger.Casing is airtight to reach the requirement of IP55 degree of protection.
