Description
technical field:
The present invention relates to one more changing device, particularly relate to a kind of HGIS isolating switch buffer and change special equipment.
background technology:
Station, 1000kV ultra high voltage Nanyang is maximum, the state-of-the-art extra-high-voltage alternating current transformer station of technical merit of construction scale in the world so far, relate to interregional grid safety, in system, status is important, 1000kV UHV demonstration project connects North China Power Telecommunication Network and Central China Power Grid two large regions electrical network, as the transregional significant transportation passage of China's energy, long-term safety stable operation tool is of great significance.1000kVHGIS equipment, as the main equipment of ultra high voltage system, has a very important role.
Because 1000kV isolating switch moving contact adopts vertical mode of operation, through-current capability reaches 8000A, size and the weight of dynamic/static contact are larger, therefore divide at isolating switch, closing operation time, due to the reason of moving contact weight, making mechanism's load difference greatly, for overcoming the problems referred to above, have employed moving contact bascule.1000kV moving contact and fixed contact of isolating switch complex structure and weight are comparatively large, for reliable, and the mode that moving contact and fixed contact of isolating switch all adopts supporting insulator to support.Because the weight of moving contact is comparatively large, divide-shut brake needs energy comparatively large, and in order to avoid device damage, electric spring operating mechanism needs buffer to be dropped into buffering in spring energy release simultaneously.Buffer is made up of piston, aircraft fluid, tank body, oil filler point etc.But since putting into operation, because the aspects such as equipment manufacture and western developed country all exist larger gap.West centuries industrial development course we cannot surmount with decades, buffer machine work, the reason of the aspects such as manufacturing technology level, technical force, product structure, repeatedly there is buffer oil impregnate defect in 1000kVHGIS isolated switchgear, brings very large hidden danger to device security stable operation.After buffer leakage of oil, if do not changed in time it, then can not discharge comparatively macro-energy to isolating switch spring operating mechanism to cushion, during operation, HGIS isolating switch internal structure will be caused to damage, if charging operation, the pernicious consequences such as 1000kVHGIS isolated switchgear flashover, blast, tripping operation, ultra high voltage system shutdown may be caused.Great impact is caused on extra-high voltage equipment and even on national interconnected network system operation mode, and large losses load, cause very big economic loss.
According to the vertical mode of operation of isolating switch moving contact, no matter isolating switch is at open position or closing position, in the process changing defectiveness element, all need enough power tension moving contacts, make its divide-shut brake speed, time, stroke all small change can not occur.Traditional mechanism case key position element replacement, in order to ensure that its speed, time, stroke are constant, the conservative way all adopting plenum interior to enter people processes, have a strong impact on maintenance duration, main manifestations is: 1, need reclaim disconnector cabinet SF6 gas, every complex processes such as adjacent air cells pressure reduces by half, test, affect the utilization rate of SF6, be also unfavorable for environmental protection; 2, need recruitment appliance material many, 3, the repair time is long, (144 hours) time uninterruptedly rushes to repair all through the night at least to need to reach 6 days under normal circumstances, if for sleety weather or air humidity are more than 80%, then relevant work can not be carried out in scene, needs are postponed according to weather conditions are corresponding by the operating time, possess very big uncertainty.
summary of the invention:
Technical problem to be solved by this invention is: overcome the deficiencies in the prior art, there is provided a kind of structure simple, be easy to carry, can disassemble, problem that solution personnel cause the repair time long when entering air chamber work, special equipment changed by the HGIS isolating switch buffer also with the function that uses manpower and material resources sparingly.
Technical scheme of the present invention is: special equipment changed by a kind of HGIS isolating switch buffer, comprise two cushion block folder, described pair of cushion block folder is arranged on isolating switch transmission device, described pair of cushion block folder comprises supporting bracket and connecting bolt, described supporting bracket is provided with bolt hole, described bolt hole is two, described supporting bracket is two, described connecting bolt is through bolt hole, described isolating switch transmission device comprises connecting rod, balancing spring and triangle connecting lever, described connecting rod is two, described two connecting rods are connected by triangle connecting lever, described triangle connecting lever is connected with balancing spring, described supporting bracket is arranged between triangle connecting lever and balancing spring, a described connecting rod is connected with mechanism case transmission output shaft, another connecting rod is connected with isolating switch transmission input shaft.
Described bolt hole is arranged on the two ends of supporting bracket, and described supporting bracket is insulating rectangular block, and described connecting bolt is two, and described supporting bracket is provided with groove.
The invention has the beneficial effects as follows:
1, the problem that the present invention is easy to carry, can disassembles, solution personnel cause the repair time long when entering air chamber work, also has the function that uses manpower and material resources sparingly, increases work efficiency.
2, the present invention is fixed isolating switch connecting rod balancing spring place, to isolating switch, external agency positions locking, can ensure in Renewal process, moving contact and fixed contact of isolating switch invariant position, can ensure that 1000kVHGIS isolating switch divide-shut brake speed, time, stroke are all constant, improve and change efficiency, reduce interruption duration, improve ultra high voltage system reliability.
3, the present invention is according to 1000kV isolating switch special construction, after having a power failure during isolating switch open position, pad with two cushion block folder between triangle connecting lever and balancing spring, prevent from body contacts from conducting oneself with dignity to sink, locking 1000kV isolating switch moving contact position, on plenum interior without impact, so enter air chamber without personnel, just can change it.
4, the present invention can be modified to size by cutting equipment, can meet the situation of triangle connecting lever connecting rod different between balancing spring, and supporting bracket is provided with groove, while improving stability maintenance, personnel can also be facilitated to operate.
