Abstract
The utility model discloses an interlocking mechanism of switch room of a circuit breaker cabinet for a ring net. The interlocking mechanism comprises a lock head, a lock mounting plate, a spring pad, an interlocking sheet and a guide rod, wherein the mounting plate is fixedly arranged at the vicinity of the disconnecting switch of the circuit breaker cabinet for the ring net; the lock head is arranged on the lock mounting plate through a mounting hole and passes through one end of the mounting hole so as to be connected with the guide rod; one end of the interlocking sheet is fixedly arranged at the end part of the guide rod through a screw; the spring pad is arranged between the cap of the screw and the interlocking sheet; the other end of the interlocking sheet shields the operating hole of the disconnecting switch; when a key is rotated by 90 degrees in the lock head, the guide rod drives the interlocking sheet to move, so as to enable the guide rod to arrive at an extreme position, so that the end part of the interlocking sheet does not shield the operating hole of the disconnecting switch; and when the key is pulled out, the guide rod drives the interlocking sheet to return to the original position, and the end part of the interlocking sheet shields the operating hole of the disconnecting switch. The interlocking mechanism disclosed by the utility model can be used for realizing the interlocking of the switch room in the cabinet by virtue of a simple method, so that the cost is lowered.
Description
Technical field
The utility model relates to a kind of looped network and uses breaker cabinet, and particularly a kind of looped network belongs to the high-tension apparatus technical field with the interlocking device of breaker cabinet switch room.
Background technology
At present, the installation of high-voltage board must meet " five is anti-" requirement.Be mainly: prevent that mistake from dividing, mistake is closed circuit breaker; Prevent the on-load branch, close isolating switch; Prevent charged extension (closing) earth connection (earthed switch); Prevent to be with earth connection (switch) to close a floodgate; Prevent mistakenly entering charged chamber.
Isolating switch in the breaker cabinet and circuit breaker must be interlocked, that is on the normal occlusion major loop time, the isolating switch that closes earlier, after the circuit breaker that closes; When breaking off major loop, separate the separate isolated again switch of circuit breaker earlier.Because have only the circuit breaker just can charged deciliter major loop.The way of existing circuit breaker cabinet is on on-load switch, to add two locks to interlock, and these two lock prices are very high.
Primary structure and the principle used: the interlocking of isolating switch and circuit breaker is interlocked through two locks, one key, that is the key of circuit breaker is inserted on the circuit breaker and can carries out the operation of breaker closing, and the key of extraction circuit breaker can't close circuit breaker.Isolating switch also is the same, plugs the key isolating switch that just can close.Circuit breaker and isolating switch are interlocked simultaneously, and isolating switch can't be operated when the key of circuit breaker was inserted on the circuit breaker.Through the quantity of control key, that is two locks, one key realizes interlocking, two switches can not be simultaneously can deciliter.Existing interlocking is to realize through the interlocking gear of special use, and this special mechanism has two locks, costs an arm and a leg, and reaches thousands of yuan, and price is very expensive for the user.
The utility model content
The utility model purpose: to the problems and shortcomings that exist in the prior art, the utility model provides the interlocking device of a kind of looped network simple in structure, lower-cost with the breaker cabinet switch room.
Technical scheme: a kind of looped network comprises tapered end, lock mounting panel, bullet pad, locking plate and guide rod with the interlocking device of breaker cabinet switch room; Said lock mounting panel is fixed near the handle hole of looped network with the isolating switch of breaker cabinet; Said tapered end is fixed on the lock mounting panel through installing hole, and the end that tapered end passes installing hole is connected with guide rod;
Said locking plate one end passes through screw in the end of guide rod, and is provided with the bullet pad between screw cap and the locking plate, and the other end of locking plate shelters from the handle hole of isolating switch; When through key when tapered end intort 90 is spent, guide rod drives the locking plate displacement, makes guide rod reach the limit of the position; Thereby the handle hole of isolating switch is no longer blocked in the end that makes locking plate; Realize the closing operation of isolating switch, when key is pulled out, guide rod drives locking plate and recovers the origin-location; The end of locking plate shelters from the handle hole of isolating switch, cannot carry out the closing operation of isolating switch.
Operation principle: this utility model utilization is locked in the displacement of the elongation generation locking plate of guide rod when unblanking, and the position of this displacement just in time makes locking plate no longer block the gathering hole of deciliter isolating switch.When the key of lock is just in time sheltered from the handle hole of isolating switch by locking plate recovery origin-location pulling up after, the operation that isolating switch can't carry out deciliter.Its principle is to regulate the position of locking plate through the displacement that key unlocking forms, and comes the gathering hole of folding isolating switch with this.
Beneficial effect: compared with prior art, the looped network that the utility model provided is with the interlocking device of breaker cabinet switch room, and the interlocking with switch room in the simple method realization cabinet greatly reduces cost.
Description of drawings
Fig. 1 is the structural representation of isolating switch open mode among the utility model embodiment;
Fig. 2 is locked the structural representation of state for isolating switch among the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, further illustrate the utility model.
As shown in Figure 1: the disclosed looped network of present embodiment comprises tapered end 1, lock mounting panel 2, bullet pad 3, locking plate 4 and guide rod 5 with the interlocking device of breaker cabinet switch room; Lock mounting panel 2 is fixed near the handle hole 7 of looped network with the isolating switch of breaker cabinet; Tapered end 1 is fixed on the lock mounting panel 2 through installing hole, and the end that tapered end 1 passes installing hole is connected with guide rod 5;
As shown in Figure 1, when through key 8 when tapered end 1 intort 90 is spent, guide rod 5 drives locking plates 4 displacements; Make guide rod 5 reach the limit of the position; Thereby the handle hole 7 of isolating switch is no longer blocked in the end that makes locking plate 4, and this moment, guide rod 5 reached the limit of the position, can carry out the closing operation of isolating switch.When key 8 is pulled out, guide rod 5 drives locking plates 4 recovery origin-locations, and the end of locking plate 4 shelters from the handle hole 7 of isolating switch.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement, these improve the protection range that also should be regarded as the utility model.
