Abstract
The utility model discloses an outdoor high-voltage alternating current porcelain column by-pass switch. The high-voltage alternating current porcelain column by-pass switch comprises three monopoles. Each of the monopoles comprises an arc extinguish chamber, an insulated supporter, and an operating mechanism. The top end of the insulated supporter is provided with a shell. The shell is connected with the arc extinguish chamber. The outer sides of the arc extinguish chamber are provided with equalizer rings. The bottom portion of the insulated supporter is provided with the operating mechanism. A transmission connecting lever is provided in the shell. The operating mechanism is a hydraulic spring operating mechanism. The LW-1100 by-pass switch of the utility model meets the requirement of the short by-pass switch product closing time, and the product has a simple overall structure, superior breaking performance, and high reliability.
Description
Technical field:
The utility model relates to the high voltage electric power equip ment field, particularly a kind of be used for being in parallel with series capacitor and its overvoltage protection make line current within a certain period of time or continuous by the equipment of by-pass switch or circuit breaker and so on.
Background technology:
Along with the fast development of national ultra high voltage, improve the reliability and the transfer efficiency of UHV transmission line, be the international headache that state net company need solve; The LW-1100 by-pass switch is as the visual plant in the extra-high voltage series compensation station, and system requires very high to performance of products, does not still have the product of this type at present both at home and abroad, does not have ripe experience and can use for reference, and all start anew.Existing by-pass switch overall product complex structure, break performance is poor, and reliability is not high.
The utility model content:
In order to solve in the prior art existing by-pass switch overall product complex structure, break performance is poor, reliability is not high shortcoming.
The purpose of the utility model is to overcome the shortcoming of prior art, and a kind of outdoor high-voltage alternating current porcelain knob by-pass switch is provided, and this high-voltage alternating porcelain knob by-pass switch comprises three one poles, and each one pole comprises arc control device, insulation column and operating mechanism.
Said insulation column top is provided with the body, is connected with arc control device on the body, in the arranged outside of arc control device grading ring is arranged; Said insulation column bottom is provided with operating mechanism.
Be provided with transmission crank arm in the said body.Said operating mechanism is a hydraulic pressure spring operating mechanism.
The LW-1100 by-pass switch of the utility model has satisfied the short requirement of by-pass switch product closing time, and overall product is simple in structure, and break performance is superior, and reliability is high.
Description of drawings:
Fig. 1 is the utility model LW-1100 by-pass switch general shape structure chart
Fig. 2 is that the utility model LW-1100 by-pass switch arc control device connect sketch map
Fig. 3 is the utility model LW-1100 by-pass switch body kind of drive figure
Wherein: 1 is arc control device; 2 is the body; 3 is grading ring; 4 is insulation column; 5 is operating mechanism; 7 is transmission crank arm.
Embodiment:
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
(1) referring to Fig. 1, the interrupting porcelain insulator of LW-1100 by-pass switch adopts 1400mm, does not have shunt capacitor, has reduced the weight of switch arc control device.This overall structure is simple and reliable, has improved the anti-seismic performance of product simultaneously.
(2) referring to Fig. 1, Fig. 2, LW-1100 by-pass switch arc control device body inverted design, opposite with the kind of drive in the ordinary porcelain pillar double break mouth circuit breaker body, adopt and close the kind of drive that the branch operation is exchanged, promptly mechanism upwards pushes away, the operation of arc control device separating brake; Mechanism is to drop-down, and arc control device close a floodgate and move, and the drive mechanism that adopts divide-shut brake to exchange has guaranteed the requirement of by-pass switch closing time less than 35ms;
The LW-1100 by-pass switch is the double break mouth structure, is not with shunt capacitance, and every product is made up of three one poles, and each one pole comprises arc control device, insulation column and operating mechanism.CYA8G hydraulic pressure spring operating mechanism of the every utmost point adapted of product, monopolar operation, three-phase is electric-linked.
The utility model is according to the product testing program, and its parameter all meets the test requirements document of GB/T6115.2-200 " series capacitor bank is used protection equipment " and IEC62271-109 " by-pass switch is used in the high-voltage alternating series connection ", and concrete parameter sees the following form.
Above content is to combine concrete preferred implementation to further explain that the present invention did; Can not assert that embodiment of the present invention only limits to this; Those of ordinary skill for technical field under the present invention; Under the prerequisite that does not break away from the present invention's design, can also make some simple deduction or replace, all should be regarded as belonging to the present invention and confirm scope of patent protection by claims of being submitted to.
