Description

A kind of high pressure contact cabinet with secondary phase checking device
Technical field
The utility model belongs to the high pressure contact cabinet technical field of power equipment, is specifically related to one kind and carries secondary nuclear phase The high pressure contact cabinet of device.
Background technology
The indoor clad withdrawal-type AC metal-enclosed switch cabinet of KYN28-12 types, suitable for three-phase alternating current 50Hz, specified electricity 3.6kV ~ 12kV power system is pressed, for receiving and distributing electric energy, and carries out circuit control, protection and detection.With suitable The advantages of Ying Xingguang, reliability be high, non-maintaining all the year round, operation light and flexible, equipment interlocking device is simple and reliable, fully meets The requirement of " five is anti-".This kind of switch cubicle has become main force's cabinet type of medium voltage switchgear equipment, and the 10kV that the country is installed at present is high Power distribution cabinet is pressed, the overwhelming majority is KYN28-12 types.In recent years, as the healthy and rapid development of China's economic, electricity needs are lasting Rapid growth, many power customers all employ double loop 10kV electricity for the consideration of electricity consumption reliability, security effectiveness etc. Source powers.Double loop 10kV power supply power-supplying forms, it is desirable to nuclear phase check and correction must be carried out to two-way power supply, this is by power system Required by self-characteristic, because we power using three-phase alternating current system at present, this three-phase is A phases, B phases, C respectively Phase, the delay between three-phase is 20/3ms, and because three-phase voltage current is sine wave, so that between phase and phase Line voltage is able to remain 10kV.
If two-way power supply accesses same group of power distribution cabinet simultaneously if, if proofreaded without nuclear phase, it is possible to I power supplys A phases and the B phases of II power supplys(C phases)Side by side together, due to A phases and B phases(C phases)Between delay, so as to directly forming phase and phase Between line voltage difference, phase fault will be produced immediately, so as to set off an explosion, flame, the accident such as power failure.Even if two Same group of power distribution cabinet is accessed during the power supply difference of road, if proofreaded without nuclear phase, and during phase sequence factual error, will also result in and connect Three-phase load(Such as:Motor etc.)Produce reverse or can not normal work situation.
Therefore, all Electricity customers of power system requirements, every client using dual power supply, must carry out before power transmission Nuclear phase proof-reading, it is ensured that in the case where two power phases are consistent, can just come into operation.Because KYN28-12 cabinets are complete Metal armouring cabinet, its 10kV main bus-bar are located in bus-bar room, are full-closed structure.Existing nuclear phase equipment --- 10kV nuclear phases simultaneously Instrument is by test system main frame(Receive), X collectors(Transmitting), Y collectors(Transmitting)Formed, wherein X(Y)Collector uses Telescopic handle insulating bar(The long 650mm of retracted mode, the long 3300mm of elongation state), when professional operator measures at the scene, Collector is in elongation state, while underfooting pad felt pad, wears insulating boot, tape insulation gloves can be operated.But by Closed state is in bus-bar room in cabinet, collector can not be allowed to carry out nuclear phase close to charged generatrix;KYN28-12 is room simultaneously Interior cabinet, when the interior space is smaller, the insulating bar of collector can not all stretch out, so as to bring danger to nuclear phase work.So When carrying out nuclear phase at the scene, the breaker that get in touch with cabinet can be shaken out, while the safety screen of contact box is given and blocked by force, from And expose the 10kV live parts of upper and lower contact box, nuclear phase work is carried out using collector by two professionals, is so done If, have the disadvantage that, 1, safety coefficient it is low, because the elongation of insulating bar can not reach 3300mm, it is strong to reduce its insulation Degree, easily causes false touch electrification;2nd, there is damage to equipment, when by force by the safety screen of contact box to if blocking, to it Baffle mechanism can cause to damage, and it is unable to dexterous actions later or is acted not in place;3rd, the distance between upper and lower contact box is 275mm, when two insulating bars insert upper and lower contact box simultaneously, the distance of its insulating bar front end is close, particularly different phases When, easily cause the phenomenon that breakdown is insulated and discharged;4th, cause the waste of human resources, need at least three professionals during the phase of school Carry out simultaneously, two people hold X (Y) collector respectively, and a people holds test main frame to be tested.
The content of the invention
For insufficient present on, the utility model overcome existing equipment exist safety coefficient it is low, to equipment damage compared with Greatly, the problems such as easily causing discharge in insulation phenomenon and causing waste of human resource, a kind of height with secondary phase checking device is proposed Pressure contact cabinet.
The technical solution of the utility model is:Outside a kind of high pressure contact cabinet, including high-voltage board with secondary phase checking device Shell, upper, middle and lower door-plate is provided with high-voltage board shell, multiple sensing pillars are installed, positioned at busbar chamber of high-voltage switch cabinet in high-voltage board I sections bus sensing pillar be connected with stationary contact box head, positioned at high-voltage board Current Mutual Inductance room II sections bus sense pillar connect respectively It is connected on current transformer and stationary contact head cartridge;Complex protection device and electrification display are installed in upper door-plate;It is provided with middle door-plate Circuit breaker cart, the sensing pillar in bus-bar room are connected with the corresponding terminal of I section bus electrification displays, current transformer room Interior sensing pillar is connected to the corresponding terminal of II section bus electrification displays by special split-phase color separation secondary line.
The described high pressure with secondary phase checking device gets in touch with cabinet, and secondary test is provided with the panel of the electrification display Electric hole and powered indicator lamp.
The described contact cabinet of the high pressure with secondary phase checking device, the I sections bus electrification display and II section bus belts Electric display is mounted on instrument board.
The described contact cabinet of the high pressure with secondary phase checking device, the sensing pillar of I section buses are electric by the safety after decompression Pressure is sent on HL1 electrification displays, and safe voltage is sent on HL2 electrification displays by the sensing pillar of II section buses.
The beneficial effects of the utility model are:The utility model is novel in design, and installation is simple, because high pressure gets in touch with its in cabinet The sensing pillar of transformer room must fill with electrification display, and the utility model need to only increase a set of in main bus-bar room; Nuclear phase is convenient, and one man operation can complete nuclear phase work;Safety coefficient is high, and only 100V is pressed by sensor conducts electricity, so When carrying out nuclear phase check and correction to equipment action can be completed using low pressure instrument, avoid and connect with high voltage alive equipment Touch;To the various facilities of cabinet without any damage, the safety protection level and the service life time limit of cabinet are improved;For meeting phase The high pressure contact cabinet of design code arrangement is closed, the utility model can carry out nuclear phase school to being required around equipment without operating space Test work.
