Abstract
The utility model discloses a control device of a water resistance cabinet, which includes a housing; a lead outgoing hole is formed on the housing; the water resistance cabinet is mounted in the housing, one end of the water resistance cabinet is connected with a motor through a first controller by a lead, and the other end of the water resistance cabinet is connected with an external power supply through a second controller; the motor is connected with external power supply through a third controller; and the third controller is connected with the first controller and the second controller respectively through a time controller, and is connected with the water resistance cabinet through another lead. The utility model has the advantages that the water resistance cabinet can be rapidly cut off after the motor runs under full pressure, and the energy consumption of the water resistance cabinet is reduced; the resetting time of the water resistance cabinet is shortened, and the reuse of the water resistance cabinet is facilitated; the control is fully automatic, and no manual operation is required; and the structure is simple and reasonable, and the manufacturing cost is low.
Description
Technical field
The utility model relates to a kind of motor reduced-voltage starting device field, specifically is a kind of water resistance cabinet control device.
Background technology
In some large-scale synchronous machines, because starting current is bigger, start relatively difficulty, usually need to be connected in series the water resistance cabinet and reduce starting current, promptly when normal the startup, disconnect master controller and connect the water resistance cabinet, make the motor reduced voltage starting, the water resistance cabinet generally is when pole plate runs to minimum point therein, be that resistance hour is sent the total head signal, the master controller closure is normally moved motor then, and the signal that sends excision water resistance cabinet power supply simultaneously disconnects the water resistance cabinet.But in practice, because the morning that motor total head run signal is sent, generally want Zao 3-5 second than the signal that disconnects the water resistance cabinet, this has just caused the water resistance unnecessary loss of energy cashier's office in a shop, and make that resetting of water resistance cabinet is slow, and enterprise is in order to save cost, and the water resistance cabinet generally all is to be used for the multi-section motor simultaneously, and this also just has influence on the normal startup of lower motor.
Summary of the invention
The purpose of this utility model is to provide a kind of device of water resistance cabinet control, and it can solve the deficiency that exists in the known technology, quickens the disconnection of water resistance cabinet, reduces the water resistance consumption of energy cashier's office in a shop, energy savings.
The utility model for achieving the above object, be achieved through the following technical solutions: a kind of water resistance cabinet control device, comprise housing, offer wire hole on the housing, the water resistance cabinet is installed in the housing, water resistance cabinet one end is connected by lead with motor through first controller, the water resistance cabinet other end is connected with external power source through second controller, motor is connected with external power source by the 3rd controller, the 3rd controller is connected with second controller with first controller respectively by time controller, and the 3rd controller is connected with the water resistance cabinet by lead.
Advantage of the present utility model is: disconnect the water resistance cabinet fast in motor total head operation back, the less consumption of water resistance cabinet energy; Reduce the resetting time of water resistance cabinet, be beneficial to reusing of water resistance cabinet; All control automatically need not manual operation; Simple for structure reasonable, low cost of manufacture etc.
Description of drawings
Accompanying drawing 1 is a main TV structure schematic diagram of the present utility model.
Embodiment
The utility model is the water resistance cabinet control device that is used for motor reduced-voltage starting device, comprise housing 8, offer on the housing 8 in wire hole 9. housings 8 water resistance cabinet 5 is installed, water resistance cabinet 5 one ends are connected by lead through first controller 7 and motor 1, water resistance cabinet 5 other ends are connected with external power source 3 through second controller 4, being communicated with or closing of first controller 7 control water resistance cabinets 5 and motor 1, the connection of second controller 4 control water resistance cabinets 5 and external power source or close. motor 1 is connected with external power source by the 3rd controller 2, the connection of the 3rd controller 2 control motors 1 and external power source or close. the 3rd controller 2 is connected with second controller 4 with first controller 7 respectively by time controller 6, time controller 6 can be controlled closing of first controller 7 and second controller 4 simultaneously. and time controller 6 can be the time relay or delay control switch etc. and the 3rd controller 2 is connected with water resistance cabinet 5 by lead, when water resistance cabinet 5 internal polar plates run to minimum point, be resistance hour, water resistance cabinet 5 sends communications signals for the 3rd controller 2, and the 3rd controller 2 is communicated with makes motor 1 be in the total head running status.
During the utility model used, motor 1 cut out the 3rd controller 2 when starting, open first controller 7 and second controller 4, water resistance cabinet 5 is connected in the circuit of motor 1, makes motor 1 reduced-voltage starting.The resistance of water resistance cabinet 5 reduces gradually, when arriving minimum point, water resistance cabinet 5 sends connection signal for the 3rd controller 2, the 3rd controller 2 is connected external power source 3 and motor 1, the 3rd controller 2 signals to time controller 6 then, time controller 6 time-delay control first controller 7 and second controllers 4 cut off water resistance cabinet 5 rapidly, thereby have reduced the loss of energy on the water resistance cabinet 5.
