It is standby to be safeguarded.Therefore, the quality of rapid closing switch work, directly influences the safe operation of electric system.
Utility model content
The purpose of this utility model be to provide it is a kind of it is rational in infrastructure, efficiency of transmission is high, stable drive is reliable, operating mechanism letter
It is single, the 72.5kV rapid closing switchs of dependable performance.
The technical solution adopted in the utility model is：A kind of 72.5kV rapid closing switchs, including arc-chutes, pedestal, branch
The groups such as frame, girt, CT26 mechanisms, divide-shut brake instruction device, transmission case, insulated tension pole, interior connecting lever, transmission arm, outer connecting lever
Into part；Arc-chutes are fixed on by screw on pedestal, and pedestal is connected by screw with stent；72.5kV rapid closing switch
Middle phase transmission case is connected by outer connecting lever with CT26 mechanism hinges, interior connecting lever is provided in transmission case, interior connecting lever one end is with going out
The insulated tension pole connection of arc chamber, the other end are connected by splined shaft with the transmission arm on the outside of transmission case, the transmission arm of middle phase switch
It is connected by axis with outer connecting lever, the transmission arm of threephase switch is connected by girt, outer connecting lever rotation direction and conventional open circuit
Device is opposite.Divide-shut brake instruction device is connected by axis with transmission arm.
The rapid closing switch closing time of the utility model is short, and arc-chutes portion of techniques scheme is as follows：It opens away from by 110mm
It is changed to 60mm；Stroke is changed to 100mm by 150mm；The excess of stroke is all mutually 40mm with former breaker.Because the actual fortune of the breaker
Row voltage is relatively low, considers to reduce fracture distance, and stroke reduces, and the excess of stroke is constant, ensures contact, so can effectively subtract
Small closing time.
The rapid closing switch closing time of the utility model is short, and running part technical solution is as follows：The rapid closing is opened
Pass is by the divide-shut brake location swap of conventional 72.5kV breakers, and arc-chutes stroke is changed to 100mm, therefore devises rotation side
To the outer connecting lever opposite with routine, length is special；Mechanism installation site changes, and designs special pedestal installing mechanism；
The rapid closing switch closing time of the utility model is short, and technical solution is as follows in terms of Secondary Design：This is quickly closed
Lock switching requirements are controlled using double closing circuits, double sub-gate circuits, and require secondary point, close circuit need to include a full set of interlocking point,
Anti-jump loop etc., therefore secondary drawing is devised for the particularity, the conversion of former brake division loop of circuit breaker is closed a floodgate in order to control and is grasped
Make, former closing circuit of circuit breaker converts sub-switching operation, and auxiliary switch normally-open normally-close is adjusted to inverse state in order to control, meets
The control requirement of closing switch.
The beneficial effects of the utility model are that breaker three-phase is connected by a set of transmission device, realize that breaker three is identical
When breaking-closing operating, have rational in infrastructure, efficiency of transmission is high, and performance is stablized, it is simple and reliable the advantages that.
Description of the drawings
Attached drawing 1 is the structure diagram of the utility model.
In figure, 1 arc-chutes, 2 pedestals, 3 stents, 4 girts, 5
CT26 mechanisms, 6 divide-shut brake instruction devices, 7 transmission cases, 8 insulated tension poles, connecting lever, 10 transmission arms, 11 outer connecting levers in 9.
Specific embodiment
The utility model is further described in conjunction with attached drawing, Fig. 1 is a kind of example of the utility model.It is a kind of
72.5kV rapid closing switchs include arc-chutes 1, pedestal 2, stent 3, girt 4, CT26 mechanisms 5, divide-shut brake instruction device
6th, the components such as transmission case 7, insulated tension pole 8, interior connecting lever 9, transmission arm 10, outer connecting lever 11.Arc-chutes 1 are fixed on by screw
On pedestal 2, pedestal 2 is connected by screw with stent 3；The middle phase transmission case 7 of 72.5kV rapid closing switchs is by screw with going out
Arc chamber 1 is connected；Interior connecting lever 9 and transmission arm 10 are externally provided in transmission case 7；The transmission arm 10 of three-phase is connected by girt 4,
The transmission arm 10 of middle phase is connected by axis with outer connecting lever 11；Outer connecting lever 11 is connected with CT26 mechanisms 5 hinges；Transmission case 7 it is interior

It connects, outer 10 rotation direction of connecting lever is opposite with regular circuit breakers.Divide-shut brake instruction device 6 is connected by axis with transmission arm 10.Arc extinguishing
Room 1 is opened away from 60mm is changed to by 110mm, and it is all mutually 40mm that stroke is changed to the 100mm excess of stroke with former breaker by 150mm.
The closing time of the utility model is short, and technical solution is as follows in terms of Secondary Design：Former brake division loop of circuit breaker is turned
Control closing operation is changed to, former closing circuit of circuit breaker converts sub-switching operation, and auxiliary switch normally-open normally-close is adjusted in order to control
For inverse state, meet the control requirement of closing switch.
When operating operating mechanism, operating mechanism output shaft drives transmission arm by outer connecting lever, is driven by girt
Other transmission arm action, under transmission arm effect, interior connecting lever drives arc-chutes to act by insulated tension pole, completes divide-shut brake behaviour
Make.
It can be seen that the utility model has rational in infrastructure, performance stabilization, and it is simple and reliable, it can realize the fast of breaker
