Furthermore, the maintenance is easy.
Description
Technical field
The utility model relates to a kind of banbury, specifically a kind of banbury high-voltage motor speed-regulating control device.
Background technology
At present, generally adopt direct current to drag to the motor of high-power (more than the 1500KW), as the equipment such as banbury of rubber enterprises such as tire production producer.Its power factor is low, harmonic content height, maintenance of motor cost height.The employing high voltage converter is arranged now, and (6 KV～22KV) drag alternating current machine, and its high voltage converter manufacturer often only provides a three-phase isolation switch in the high-pressure side.Like this, when the user used, when equipment was in an emergency, can not accomplish that local high pressure is anxious stopped, and overstep tripping to user's high voltage substation, and the distance of most of users' high voltage substation away from having quite from the subscriber equipment scene; The 2nd, during overhaul of the equipments, can not determine whether circuit really disconnects; The 3rd, high voltage converter easily produced about ten times high voltage surge electric current when high voltage source was closed a floodgate, and easily overstep tripping is to user's high voltage substation.
Summary of the invention
The banbury high-voltage motor speed-regulating control device of high voltage surge electric current when the purpose of this utility model provides a kind of effective minimizing and starts.
The utility model is to adopt following technical scheme to realize its goal of the invention, a kind of banbury high-voltage motor speed-regulating control device, it comprises the high voltage substation switch element that connects with the high pressure inlet wire, the high voltage converter that is connected with lightning arrester FV, the high-voltage motor that connects with high voltage converter, and the high voltage substation switch element connects with high voltage converter by high pressure wire inlet unit, high voltage startup unit; Described high pressure wire inlet unit comprises the electrification display P1 that connects with high voltage substation switch element out-put supply, three-phase isolation switch QS1 and the vacuum contactor KM1 of band ground connection cutter; Described high voltage startup unit comprises the current-limiting resistance R that connects with the output of high pressure wire inlet unit, the vacuum contactor KM2 in parallel with current-limiting resistance R.
Be convenient maintenance, the output of the vacuum contactor KM1 of the utility model high pressure wire inlet unit is connected with electrification display P2.
Because adopt technique scheme, the utility model has been realized goal of the invention preferably, it is simple in structure, and starting current is not more than 1.5 times of rated current, and high voltage converter is had good protective effect; Simultaneously, can carry out interruption maintenance to equipment easily.
Description of drawings
Fig. 1 is structural representation block diagram of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, a kind of banbury high-voltage motor speed-regulating control device, it comprises the high voltage substation switch element that connects with the high pressure inlet wire, the high voltage converter that is connected with lightning arrester FV, the high-voltage motor that connects with high voltage converter, and the high voltage substation switch element connects with high voltage converter by high pressure wire inlet unit, high voltage startup unit; Described high pressure wire inlet unit comprises the electrification display P1 that connects with high voltage substation switch element out-put supply, three-phase isolation switch QS1 and the vacuum contactor KM1 of band ground connection cutter; Described high voltage startup unit comprises the current-limiting resistance R that connects with the output of high pressure wire inlet unit, the vacuum contactor KM2 in parallel with current-limiting resistance R.
Be convenient maintenance, the output of the vacuum contactor KM1 of the utility model high pressure wire inlet unit is connected with electrification display P2.
High voltage substation switch element described in the utility model comprises three-phase isolation switch, insurance, voltage transformer, vacuum circuit-breaker, the current transformer of band ground connection cutter.
During the utility model work, according to the watt level of banbury with high-voltage motor, determine the resistance of current-limiting resistance R.During startup, the vacuum contactor KM1 that closes, current-limiting resistance R make starting current be not more than 1.5 times of rated current, after having started, and the vacuum contactor KM2 that closes, excision current-limiting resistance R enters normal operation.
When the emergency shutdown requirement appears in equipment, disconnect the vacuum contactor KM1 on the high pressure wire inlet unit, disconnect three-phase isolation switch QS1 and reliable ground again, electrification display P2 indication is cut off the power supply, can realize that device security has a power failure and the safety inspection of equipment.
