Abstract
一种同一机构中两台单相电机的共用电容装置,装置内有两个串连的电容,从串连的两个电容的三个端点连接三个接线点,从其中的一个电容的两端连接另外两个接线点。使用本装置的优点是:提高了单相电容运转电机的起动力矩1倍左右。节省一个起动电容,降低成本10%至15%。本线路同样适用于非低温条件下两台单相双值电容电机在同一机构的共用系统。
A common capacitor device for two single-phase motors in the same mechanism. There are two capacitors connected in series in the device. Three connection points are connected from the three terminals of the two capacitors connected in series, and two terminals of one capacitor are connected to each other. Connect the other two terminal points. The advantage of using the device is that the starting torque of the single-phase capacitor running motor is increased by about 1 time. Save a starting capacitor and reduce the cost by 10% to 15%. This line is also applicable to the shared system of two single-phase double-value capacitor motors in the same institution under non-low temperature conditions.
Description
The utility model belongs to starting device of motor, the shared capacitive means of two monophase machines in particularly a kind of same mechanism.
The equipment that has at present is the motor that has in same mechanism more than two or two, and these two motors are startings successively, then running simultaneously.In the ordinary course of things, two single-phase two-capacitance capacitive monophase machines are separate, and every has two electric capacity, and one is the electrolysis starting capacitance, and one is metal film electric capacity.Its shortcoming is (below subzero 20 degree) electrochemical capacitor cisco unity malfunction under cryogenic conditions, when the cancellation starting capacitance, after using capacitor-operated motor instead, starting torque lower (0.35-0.55 that general straight power distance is a rated moment doubly), motor can not satisfy the requirement of main frame, the machine cisco unity malfunction.The design's purpose is by improving structure, can avoid using the electrolytic starting capacitance, can improving the purpose of single-phase capacitor-operated motor starting torque again.
The purpose of this utility model provides the shared capacitive means of two monophase machines in a kind of same mechanism, overcomes above-mentioned shortcoming and defect.
The purpose of this utility model is achieved in that
The shared capacitive means of two monophase machines in a kind of same mechanism, it is characterized in that: its device has two set of connections point, one group of three wiring point, another organizes two wiring points, the electric capacity that two polyphones are arranged in the device, connect three wiring points from three end points of two electric capacity of polyphone, connect two other wiring point from the two ends of one of them electric capacity.
Two electric capacity of polyphone are metal film electric capacity.
The utility model has the advantages that:
(1) having improved the starting torque of single-phase capacitor-operated motor, is that the 0.35-55 of rated moment doubly brings up to about 1 times by original starting torque.
(2) save a starting capacitance, reduce cost 10% to 15%.
(3) this circuit is equally applicable to the sharing system of following two the single-phase two-capacitance capacitive motors of non-cryogenic conditions in same mechanism.
Below in conjunction with description of drawings embodiment:
Fig. 1 is the shared capacitive means schematic diagram of two monophase machines in the same mechanism
Fig. 2 is the internal circuit diagram of a monophase machine
Fig. 3 is the internal circuit diagram of another monophase machine
Fig. 4 is the shared capacitive means and the motor connection diagram of two monophase machines in the same mechanism
The shared capacitive means of two monophase machines in a kind of same mechanism, its device has two set of connections point, one group of three wiring point (green, yellow, white), another organizes two wiring points (green, white), capacitor C 1, C3 that two polyphones are arranged in the device, connect three wiring points (green, yellow, white) from two capacitor C 1 of polyphone, three end points of C3, connect two other wiring point (green, white) from the two ends of one of them capacitor C 3.Two electric capacity of polyphone are metal film electric capacity.
Do not have the connection capacitance point (green, yellow, white) of the motor of distribution appearance to use one group of three wiring point (green, yellow, white) of capacitive means to connect together with one; The connection capacitance point (green, white) of the motor that another distribution is held connects with another two wiring points of group (green, white) of capacitive means together.
This method is that two single-phase capacitor-operated motors are separately outside electric capacity of adapted, add a shared electric capacity again, having three electric capacity all is metal film electric capacity, concrete way is when first electric motor starting, and three electric capacity are participated in starting simultaneously, and the starting back cuts off the shared starting capacitance and the running electric capacity of second motor with centrifugal switch, and then start second motor, the starting back cuts off shared starting capacitance with centrifugal switch, after two motors successively start, and running simultaneously.
The using method key of this shared electric capacity is the use by line design and ganged switch, guarantees when first electric motor starting second motor unaffected (attached line map).
The simple practicality of the method, my company Beijing packaged food mechanical investigations slicing machine in use, two motors are respectively 4 grades of 370W (spindle motor) and 2 grades of 370W (feeding motor), the running electric capacity that uses all is 14 μ F, shared starting capacitance is 14 μ F, after this method use, by test and practical, receive obvious effects, the design has guaranteed the normal starting of slicing machine under low temperature (subzero 20 degree) condition, simultaneously also avoid the shortcoming of electrolytic starting capacitance cisco unity malfunction under cryogenic conditions, thereby be subjected to user's welcome.
This patent way is applicable to that the single-phase motor of the 10W-3.0KW small-power shared electric capacity that priority is started more than two in same mechanism uses the scope of this way.
