Abstract
The utility model relates to an RMU load switch with an inlet live blocking device, comprising a load switch operation panel, a support, a blocking slip sheet, a blocking sheet support, a spacer pin and an electromagnetic lock, wherein the support is fixedly connected with the load switch operation panel; the blocking sheet support is arranged on the support; the blocking slip sheet is arranged on the blocking sheet support; the blocking slip sheet can slide on the blocking sheet support reciprocatively; the spacer pin of the blocking slip sheet is arranged on the blocking sheet support; the electromagnetic lock is fixedly connected with the support; the electromagnetic lock can be locked or unlocked with the blocking slip sheet; and the electromagnetic lock is electrically connected with a live displayer so as to control the motion of the electromagnetic lock, thus forming the load switch inlet live blocking device. The RMU load switch with an inlet live blocking device utilizes the mode integrating the machinery with the electric to form an interlocking device together, thus satisfying the requirement for five-protection interlocking, and improving safe reliability for power supply unit operation, and has the advantages of being simple in mechanical parts, being convenient to mount, and being simple and reliable in electric connection.
Description
Technical field
The utility model relates to high-tension switch cabinet " five anti-interlockings " device, particularly relates to a kind of RMU load with the charged locking device of inlet wire and opens.
Background technology
The application of RMU in the electric power system (ring main unit) is very extensive, and a kind of main electric elements of RMU are exactly on-load switch.The on-load switch that my company adopts and the operating mechanism of on-load switch are all from Korea S's import, and on-load switch is the three-stations load switch of band grounding function.When controlling the inlet wire unit of RMU with this on-load switch, have when the end of incoming cables under the situation of electricity, former on-load switch operating mechanism still can carry out the ground connection operation to on-load switch.So just can not satisfy the relevant five anti-interlock requirements of " preventing charged mistiming splice grafting ground switch ".
The utility model content
The technical problem that the utility model will solve is to provide a kind of. mechanical and electric combining,
Machine components are simple, and are easy for installation, and electrical wiring is simple and reliable, and a kind of RMU load with the charged locking device of inlet wire that meets high-tension switch cabinet five anti-interlock requirements is fully opened.
The technical scheme that adopts is:
A kind of RMU on-load switch with the charged locking device of inlet wire comprises on-load switch guidance panel, support, locking slide plate, locking plate rack, spacer pin, electromagnetic lock.Described support is fixedly connected the on-load switch guidance panel, and the locking plate rack is housed on the support, and the locking slide plate is housed on the locking plate rack, and the locking slide plate can reciprocatingly slide on the locking plate rack, and on the locking plate rack, the spacer pin of locking slide plate is housed.Said electromagnetic lock is fixedly connected support, and electromagnetic lock can or be unblanked with the locking of locking slide plate, and electromagnetic lock is electrically connected electrification display and is used to control the electromagnetic lock action, constitutes the charged locking device of on-load switch inlet wire.
The utility model is formed interlock jointly with machinery and the electric form that combines, and has satisfied five anti-interlock requirements, has increased the security reliability of power supply unit operation, and it is simple, easy for installation to have machine components, the advantage that electrical wiring is simple and reliable.

Embodiment
A kind of RMU on-load switch with the charged locking device of inlet wire comprises on-load switch guidance panel 1, support 2, locking slide plate 4, locking plate rack 3, spacer pin 5, electromagnetic lock 6.Described support 2 is fixedly connected on-load switch guidance panel 1; Locking plate rack 3 is housed on the support 2; Locking slide plate 4 is housed on the locking plate rack 3, and locking slide plate 4 can reciprocatingly slide on locking plate rack 3, and the spacer pin 5 of locking slide plate is housed on locking plate rack 3.Said electromagnetic lock 6 is fixedly connected support 2, and electromagnetic lock 6 can or be unblanked with 4 lockings of locking slide plate, and electromagnetic lock 6 is electrically connected electrification display and is used to control electromagnetic lock 6 actions, constitutes the charged locking device of on-load switch inlet wire.
Operation principle
When electrification display detected the end of incoming cables electricity is arranged, electrification display is used to control was failure to actuate the normal battle of electromagnetic lock, and electromagnetic lock 6 is in the lock state, and makes locking slide plate 4 be in latched position (like Fig. 2).Locking slide plate 4 shelters from the ground connection handle hole 7 on the operating mechanism, and can not carry out the ground connection operation this moment to on-load switch; When electrification display detected the end of incoming cables and do not have electricity, electrification display was used to control normal action battle of electromagnetic lock, and electromagnetic lock 6 is in released state, and can push unlocked position (like Fig. 3) this moment with locking slide plate 4.Ground connection handle hole 7 on the operating mechanism exposes, and can carry out the ground connection operation this moment to on-load switch.
