Description
Technical field
The invention belongs to refrigeration compressor motor starting operation device technique field, be specifically related to the modular construction of a kind of startor for refrigeration compressor electric machine and motor-run capacitor device, motor starter and motor-run capacitor device are gathered together and form the modular of integral type
Background technology
As the industry's knowledge of the reason, in the start-up circuit of refrigerant compressor, be in series with starter, utilize starter positive temperature coefficient thermistor (english abbreviation is PTC) to be at normal temperatures little resistance conducting state, and when compressor energising starting, electric current is connected the starting circuit of compressor through PTC and with a pair of inserted sheet (claiming again contact) that the both sides of PTC electrically contact, and makes the refrigeration compressor motor starting.While is in the moment of compressor electric motor starting, electric current by the PTC that flows through generates heat rapidly PTC, and within the extremely short time, make PTC reach high value state (reaching Curie point), thereby cut off the starting circuit of compressor electric motor, make compressor enter normal operating condition; The motor-run capacitor device is that refrigeration compressor motor operation Parallel-connected Capacitor is connected between the main and sub-coil of compressor electric motor, its function is to improve rotating speed and the torque of compressor electric motor, adjust the electric current of the secondary coil of compressor, to ensure the motor reliability of operation, for example reduce electric machine temperature rise and noise.
Prior art forms independently structure each other with motor starter and the motor-run capacitor device of refrigerant compressor usually, particularly, three terminals of motor starter and compressor are matched, the motor-run capacitor device then is arranged in the terminal box that preferably is molded by plastic, and motor starter and motor performer are implemented electrical connection by wire between the two.The existing shortcoming of this version is: implement electrical connection between motor-run capacitor device and the motor starter in order to make, therefore need the motor-run capacitor device is drawn wire, draw the terminal of wire and often be difficult to guarantee with the reliability that is connected between the motor starter, namely have the bad situation of electrical connection.Again, because production technology can not reach perfect ultimate attainment consummate degree, the same existence of effect that is electrically connected of therefore drawing between wire and the motor-run capacitor device electrically contacts and namely is electrically connected the problem that effect is difficult to Reliable guarantee; Can take binding post owing to being connected between motor-run capacitor device and the motor starter, thereby cause the installation difficulty of other parts of compressor, affect installation effectiveness.
The applicant has carried out literature search, the document of searching such as CN2664280Y(improve the motor starter of structure), the CN2664281Y(motor starter), the motor starter of CN2664282Y(architecture advances), the structure improved motor starter of CN2664283Y() and CN201893740U(refrigerant compressor safety starter), etc.But these documents that are not limited to exemplify all provide motor starter and motor-run capacitor device are not organically gathered as a whole technology enlightenment.
Again, Granted publication CN201188596Y recommends have " protector for cold compressor ", this patent scheme the compressor operating capacitor to be arranged in the cavity volume of loam cake, and starter and overload protective device are arranged in the cavity volume of loam cake; And CN201674445U provides " electronic-type starter for refrigeration compressor ", and this patent scheme is arranged on motor starter and motor-run capacitor device in the same box body equally.Should say, these two patent schemes have reference for motor starter and motor-run capacitor device are gathered to be integrated and to form modular structure each other, thereby can eliminate aforementioned shortcoming to a certain extent.But there are following common shortcoming in these two patent schemes: one, patent have been paid attention to the modularization effect of self, and ignored with refrigerator in the quick location and installation effect of installation base plate; They are two years old; function singleness; for example these two patents do not have the function that transfer or the title relaying action of respective lines connection are provided for refrigerant compressor; comprise power line because connect the circuit of compressor; the compressor main line; the auxiliary line of compressor and ground protection circuit etc.; therefore; if at the supporting power line for compressor of the rational position of housing; the master of compressor; the junction block of auxiliary line and ground protection circuit and be equipped with binding post for these connections in terminal box; so not only can significantly improve standard and the regular effect on compressor connecting wire road, but also the wiring efficient that can play corresponding electrical safety effect and promote compressor.In view of these shortcoming, the applicant has done positive and useful design, and the below produces the technical scheme of introducing under this background
