Description
Technical field
The utility model relates in one and press (3-7.2kV) motor controlling cabinet, be specifically related to press (3-7.2kV) double-casing motor control cubicle in a kind of AC metal closed armored.
Background technology
Traditional motor controlling cabinet generally only has an electric motor loop, and can only control a motor, and it is high to consume energy, unstable properties, reliability is not high, and floor space is large, thus causes its fail safe greatly to reduce, and practicality is not strong.
Utility model content
For the deficiency that prior art exists, the utility model object is to provide in one to press (3-7.2kV) double-casing motor control cubicle, has two electric motor loops, and can control two motors respectively, stable and reliable for performance, practical.
To achieve these goals, the utility model realizes by the following technical solutions: middle pressure double-casing motor control cubicle, comprises cabinet, motor control unit, handcart type vacuum contactor, earthed switch, earthed switch action bars and block, armature and securing rod.Cabinet is provided with upper and lower two-layer motor control unit, handcart type vacuum contactor is provided with in described motor control unit, earthed switch etc., described handcart type vacuum contactor is provided with armature, armature is connected with securing rod, securing rod is arranged on handcart, and earthed switch is connected with earthed switch action bars and block, and described vacuum contactor is connected with main telegram in reply road by current limiting fuse.Earthed switch is connected with vacuum contactor transmission line circuit.
As preferably, described securing rod, earthed switch action bars and block are provided with interlock circuit.
As preferably, described handcart-type is tapping unit.
Operation principle of the present utility model: 1, when handcart is in service position, its vacuum contactor is in "on" position, the armature be connected with contactor, has pinned the securing rod on handcart, and handcart is fixed, and can not move; Earthed switch action bars and block have pinned earthed switch combined floodgate structure, and earthed switch can not be closed a floodgate.Otherwise only have when contactor is in gate-dividing state, handcart could move, and when handcart is in test position, earthed switch could close a floodgate.
2, when handcart is in fixing irremovable position, namely work and test position, contactor could close a floodgate.When handcart is in the centre position of work and test, securing rod is raised, and contactor has been blocked in securing rod upper end, makes it close a floodgate, meanwhile, and the chain disconnection closing circuit on latch-up structure.
The utility model divides upper and lower two-layer independent loop, can operate the electric motor loop of two 6kV 200-630kW simultaneously, its stable performance, reliable, energy-conserving and environment-protective, consume energy low.
Accompanying drawing explanation
The utility model is described in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structural representation of the present utility model.
Embodiment
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the utility model further.
With reference to Fig. 1, this embodiment is by the following technical solutions: middle pressure double-casing motor control cubicle, comprise cabinet 1, motor control unit 2, handcart type vacuum contactor 3, earthed switch 4, earthed switch action bars and block 5, armature 6 and securing rod 7, cabinet 1 is provided with upper and lower two-layer motor control unit 2, handcart type vacuum contactor 3 is provided with in described motor control unit 2, earthed switch 4, earthed switch action bars and block 5, described handcart type vacuum contactor 3 is provided with armature 6, armature 6 is connected with securing rod 7, securing rod 7 is arranged on handcart, described vacuum contactor 3 is connected with major loop by current limiting fuse, earthed switch is connected with vacuum contactor transmission line circuit.
It should be noted that described securing rod 7, earthed switch action bars and block 5 are provided with interlocking closing circuit.
In addition, described handcart type vacuum contactor 3 is tapping unit.
This embodiment has reliable interlock, when handcart is in work or test position, its vacuum contactor is in "on" position, the armature be connected with contactor, has pinned the securing rod on handcart, and handcart is fixed, can not move, otherwise only have when contactor is in gate-dividing state, handcart could move.When handcart is in fixing irremovable position, namely work and test position, contactor could close a floodgate.When handcart is in the centre position of work and test, securing rod is raised, and contactor has been blocked in securing rod upper end, makes it close a floodgate, meanwhile, and the chain disconnection closing circuit on latch-up structure.
This embodiment divides upper and lower two-layer independent loop, can operate the motor circuit of two 6kV200-630kW simultaneously, its stable performance, reliable, energy-conserving and environment-protective, consume energy low.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
