Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 to Fig. 2 has schematically shown according to high-voltage ring network switch cabinet of the present utility model.
According to one side of the present utility model, a kind of high-voltage ring network switch cabinet is provided, comprise incoming line cabinet and the outgoing line cabinet being connected with outgoing line cabinet by bus, outgoing line cabinet comprises the first mutual interlocking gear, the second mutual interlocking gear, the 3rd mutual interlocking gear, the first interlocking device, isolating switch, earthed switch, vacuum circuit-breaker and the first Xiamen.Incoming line cabinet comprises the second interlocking device, voltage transformer and the first Xiamen.The first mutual interlocking gear is located between isolating switch and earthed switch, the first mutual interlocking gear comprises the baffle plate that the first handle hole being connected with earthed switch, the second handle hole being connected with isolating switch, described the second handle hole lower end are provided with bayonet socket, the buckle being connected with the second handle hole, are connected with buckle, between the first handle hole and the second handle hole, is provided with for the chute of baffle plate is installed.The second mutual interlocking gear is located between vacuum circuit-breaker and isolating switch, the second mutual interlocking gear comprises isolated controlling connecting rod, breaker control connecting rod, disconnects and disturb pull bar, combined floodgate to disturb pull bar and catch, catch is connected with breaker control connecting rod, and be located at by the second handle hole, the first handle hole is connected with isolating switch by isolated controlling connecting rod, and described isolated controlling connecting rod, disconnection are disturbed pull bar, closed a floodgate and disturb pull bar to connect successively.The 3rd mutual interlocking gear is located between vacuum short-circuiting device and earthed switch, and the 3rd mutual interlocking gear comprises the second handle hole baffle plate and power transmission shaft, and second controls hole baffle plate is connected with circuit breaker connecting rod by power transmission shaft.Earthed switch is connected with the first Xiamen by the first interlocking device, and the first interlocking device comprises the first thimble, and first thimble one end is connected with earthed switch, and the other end is connected with the first Xiamen.Voltage transformer is connected with the Xiamen of incoming line cabinet by the second interlocking device.The second interlocking comprises electromagnetic lock and the second thimble being connected with electromagnetic lock one end, and the electromagnetic lock other end is connected with voltage transformer, and the other end of the second thimble is connected with the second Xiamen.
The operation principle of each mutual interlocking gear of the present utility model and interlocking device: the course of work of the first mutual interlocking gear is: under the state of switch cubicle closure, isolating switch closure state, baffle plate blocks the first handle hole of earthed switch on the right of chute, buckle withstands baffle plate simultaneously, baffle plate can not be moved, thus can not be to ground connection switching manipulation; Under switch cubicle open-circuit condition, baffle plate is on the left side of chute, earthed switch closure state, earthing switch operating mechanism has individual bayonet socket to withstand baffle plate simultaneously, thereby can not be to isolator operation, when only after earthed switch disconnects, buckle is removed, baffle plate release, could carry out closed procedure to isolating switch.Can avoid three-phase high-voltage to guide together and cause serious short circuit risk;
The course of work of the second mutual interlocking gear is: under switch cubicle closure state, vacuum circuit-breaker closure state, the catch being connected with breaker control connecting rod blocks the handle hole of isolating switch, now cannot operate isolating switch, when vacuum circuit-breaker disconnects, breaker control connecting rod is removed catch, handle could be injected to the second handle hole isolating switch is disconnected; Under switch cubicle open-circuit condition, when isolating switch does not have closure, the combined floodgate being connected with isolated controlling connecting rod disturbs pull bar, disconnects and disturb pull bar, can not carry out any operation to vacuum circuit-breaker, in have after isolating switch closure, the combined floodgate of removing vacuum circuit-breaker disturbs pull bar and disconnects and disturb pull bar to carry out closing operation to vacuum circuit-breaker.In the time of can avoiding closed isolating switch upset operation, cause serious high tension spark phenomenon, cause the situation of device damage and operating personnel's injures and deaths.
The course of work of the 3rd mutual interlocking gear is: in vacuum circuit-breaker closed moment, vacuum circuit-breaker can be circuit breaker connecting rod bullet up, by power transmission shaft, promote the second handle hole baffle plate and block the second handle hole, making cannot be to isolator operation, now isolating switch buckle is limiting the action of earthed switch, cannot operate earthed switch; When earthed switch closure is, earthed switch buckle is limiting isolation baffle plate, and baffle plate cannot be enjoyed movement, now cannot be to isolator operation, thus can not operate vacuum circuit-breaker.Avoid misoperation to cause device damage and operating personnel's injures and deaths
The course of work of the first interlocking device is: when earthed switch disconnects, be that earthed switch is controlled the first thimble and withstood Xiamen, it can not be improved, thereby can not open the first Xiamen; When earthed switch disconnects, thimble improves, and Xiamen can up be improved, thereby take out the first Xiamen, switch cubicle is overhauled.Under earthed switch closure state, just can open the first Xiamen and overhaul, otherwise can cause personnel's injures and deaths.
The course of work of the second interlocking device is: in incoming line cabinet, owing to there is no earthed switch, used the Xiamen of electromagnetic lock restriction incoming line cabinet, when outer circuit has electricity, voltage transformer induces the charged action of electromagnet that voltage makes electromagnetic lock, withstands the second thimble, and the second thimble withstands again the second Xiamen; Outside disconnecting, during line switching, voltage transformer is not charged, and electromagnet is failure to actuate, and now operating personnel, by the key thimble of outwarding winding, overhaul carrying out cabinet thereby can take out the second Xiamen.Must guarantee that operating personnel can not enter band electric switch, so must first disconnect outer circuit, just can make electromagnetic lock unlock, if operating personnel could be with opening electromagnetic lock unlock, and then open Xiamen maintenance.
The beneficial effects of the utility model: the mix proportion by the first mutual interlocking gear, the second mutual interlocking gear, the 3rd mutual interlocking gear, the first interlocking device and the second interlocking device five anti-safety systems of high-voltage board, can prevent operator when upset operation or operate miss, a series of safety problems that cause and supply of electric power problem.Can guarantee power network safe operation, guarantee equipment and personal safety, prevent misoperation.
The foregoing is only preferred implementation of the present utility model.For the person of ordinary skill of the art, not departing under the prerequisite of the utility model creation design, can also make some distortion and improvement, for example sanding apparatus can comprise a plurality of unit mechanisms, all belongs to protection range of the present utility model.
