Abstract
The utility model relates to a metallic seal ceramic outlet box of an electric locomotive transformer oil pump motor, which comprises a metal bottom plate that is provided with a wiring hole, and is characterized in that the wiring hole is internally inserted with a ceramic insulating body, the center of which is also plugged with a wiring bolt which is a stud bolt; the metal bottom plate is connected with the ceramic insulating body into a whole by ceramic insulating material, and the ceramic insulating body is connected with the wiring bolt into a whole by the ceramic insulating material; and the metal bottom plate and the ceramic insulating body as well as the ceramic insulating body and the wiring bolt are respectively sealed by ceramic metallization treatment to form a rigid whole. The metallic seal ceramic outlet box of the electric locomotive transformer oil pump motor leads a whole outgoing line device to form a whole by metalized welding of the ceramic insulating body and the ceramic insulating material; and the ceramic insulating body has superior ageing-resistant performance, thus not having the problem of sealing failure.
Description
Technical field
The utility model relates to a kind of motor component, be a kind of electric locomotive transformer Oil pump electrical machinery outgoing line device specifically, this kind electric locomotive transformer Oil pump electrical machinery outlet structure mainly is fit to the electric locomotive transformer Oil pump electrical machinery to be used, and also can be used for other Oil pump electrical machinery outgoing line device.
Background technology
For motor, used power supply all inserts by power line by external power source; Because external power source generally all is relatively-stationary, so the power supply of motor all needs again to be connected the introducing power supply with external power cord by power supply lead wire.The connected mode of lead-in wire and feed cable, reach the 3 kinds of methods that are connected with of motor lead and feed cable, the 1st kind is directly to link to each other, also cry and be flexible coupling, user's cable directly connects together with lead wire, junction outsourcing insulation. this connection is had relatively high expectations to the user's, in case the insulation of junction outsourcing does not reach requirement, though will there be potential safety hazard. China works out relevant for the standard that is flexible coupling, and domestic electric machine manufacturer seldom adopts and is flexible coupling, and be flexible coupling suitable voltage and power are not high, for the low pressure large-size machine, because power is big, the voltage height is not suitable for being flexible coupling; The 2nd kind is that motor lead is incorporated on the mounting panel fixing in the terminal box by gluey hermetically-sealed construction, and service cable also is connected on the terminal block, thereby links to each other with motor lead, and present motor often adopts this structure; The 3rd kind is that motor lead is crimped onto on the connection bolt, and connection bolt is connected with external power source again, has for fixing motor and adopts the method.The outlet box structure of electric locomotive transformer Oil pump electrical machinery be exactly the 2nd kind of adopting be the motor leading and connecting line method, mainly be by a terminal block, binding post is installed on terminal block, the binding post mid portion is fixed on the terminal block, the binding post two ends are respectively connection bolt, because the inside of transformer oil pump motor is the transformer oil of insulation usefulness, so seal for electric locomotive transformer Oil pump electrical machinery terminal block and binding post, can not have any slit, otherwise leakage of oil will appear, in order to guarantee sealing, present electric locomotive transformer Oil pump electrical machinery terminal block and binding post are to guarantee by the insulator that has rubber or plastics, but find in the practical application that this electric locomotive transformer Oil pump electrical machinery outlet binding post hermetically-sealed construction exists rubber or plastic ageing to cause the leakage of oil problem serious, it is low finally can insulation resistance to take place, leakage of oil and blow-by problem seriously cause the way left alone without help, operation troubless such as machine is broken.Therefore need further to be changed.
Summary of the invention
The purpose of this utility model, exactly in order to overcome the deficiency that there are problems such as encapsulant is aging, leakage of oil in existing electric locomotive transformer Oil pump electrical machinery outlet binding post hermetically-sealed construction, a kind of good airproof performance is proposed, and be not prone to problem of aging, stability is high, and electric locomotive transformer Oil pump electrical machinery outgoing line device simple in structure.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of electric locomotive transformer Oil pump electrical machinery outgoing line device, comprise a metal base plate, on metal base plate, have wiring hole, its characteristics are: be inserted with ceramics insulator in the wiring hole, the ceramics insulator center is inserted with connection bolt again, and connection bolt is a stud; And metal base plate and ceramics insulator, and ceramics insulator and connection bolt are to connect as one by ceramic insulating material, and make metal base plate and ceramics insulator by the ceramic metallization treatment technology, and ceramics insulator and connection bolt seal, and forms a rigid unitary.
The utility model makes whole outgoing line device form an integral body by the metallization welding of ceramics insulator and ceramics insulator material, and because the ageing-resistant performance of ceramics insulator is superior, the problem of seal failure therefore can not occur.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, ceramic insulating material; 2, connection bolt; 3, ceramics insulator; 4, metal base plate; 5, ceramic insulating material.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, a kind of electric locomotive transformer Oil pump electrical machinery outgoing line device comprises a metal base plate 4, on metal base plate 4, have wiring hole, its characteristics are: be inserted with ceramics insulator 3 in the wiring hole, ceramics insulator 3 centers are inserted with connection bolt 2 again, and connection bolt 2 is a stud; And metal base plate 4 and ceramics insulator 3, and ceramics insulator 3 is to connect as one by ceramic insulating material 1 and 5 with connection bolt 2, and handle by ceramic metallization and to make metal base plate 4 and ceramics insulator 3, and ceramics insulator 3 seals with connection bolt 2, forms a rigid unitary.
The key of ceramic metallization sealing is: 1, the metalized coated adhesion of ceramic insulator end face is eager to excel, and one of the insulator coating at this place is an end face, and another is the garden cylinder, and the welding difficulty strengthens.2, the compactness of insulator will be got well, and stand the test of condition of high vacuum degree, and a bit pore and slit can not be arranged.3, whole surface creepage is apart from big dielectric strength height.4, stand the welding and the machine work of subsequent processing.
