[0028] The following specific embodiments will further illustrate the utility model in combination with the above drawings. DETAILED DESCRIPTION
[0029] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The drawings illustrate several embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present invention.
[0030] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.
[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0032] In existing generator testing systems, since generators of different powers have different specifications and sizes, such as the end covers, rotor shafts, and base sizes of the generators, in order to test generators of different powers, when connecting the generators to the corresponding power sources, it is necessary to use connecting parts such as transition end covers, transition connecting shafts, and couplings of different sizes.
[0033] Because these connecting parts of different specifications need to be manufactured in advance, and these connecting parts of different specifications need to be reassembled when testing generators of different powers, it leads to high testing costs and low testing efficiency. Therefore, the utility model provides a generator testing system that only needs to replace some connecting parts when testing generators of different powers, reducing the number of connecting parts that need to be manufactured. At the same time, it is not necessary to reassemble all connecting parts when testing generators of different powers.
[0034] For details, please refer to Figure 1 , a generator testing system provided by the present invention includes a supporting platform 100, a single-point generator 200, a prime mover 300, a transmission component 400, and a measurement component 500.
[0035] During the test, the single-point generator 200 and the prime mover 300 are both installed on the support platform 100, which can provide a stable structural basis for the test system, ensure the stability of the single-point generator 200 and the prime mover 300 during operation, and reduce the test errors caused by vibration or movement. Alternatively, the support platform 100 can be a platform poured with ground cement or a platform composed of support frames with a certain height.
[0036] The basic structure of the generator can be divided into two parts according to the static and rotating parts. The static part usually includes the frame, the stator, the end cover and other components, while the rotating part usually includes the rotor, the rotor shaft, the armature, the fan and other components. The frame is the overall support of the generator, which is used to fix the armature and support the rotor and the rotor shaft together with the front and rear end covers. The frame of the generator is usually casted with cast iron or welded with steel plates. The single-point generator 200 has only one bearing, i.e., the support and rotation of the single-point generator 200 are mainly realized by one bearing.
[0037] During the test, the prime mover 300 is used to generate a rotating driving force that matches different specifications of the single-point generator 200. For example, when testing the same type of single-point generator 200, a prime mover 300 corresponding to the specification of the single-point generator 200 with the maximum power to be tested is used, so that the prime mover 300 does not need to be replaced. Preferably, the prime mover 300 is an electric motor, which can realize adjustable output power.
[0038] The transmission assembly 400 is used to transmit the rotating driving force generated by the prime mover 300 to the single-point generator 200, so as to make the rotor of the single-point generator 200 rotate.
[0039] As shown in Figure 2 , Figure 3 , Figure 4 , Figure 7 , the transmission assembly 400 includes an end cover 410, a first coupling member 420, a connecting shaft 430, a second coupling member 440 and a third coupling member 450.
[0040] The end cover 410 can match single-point generators 200 of various specifications. For example, when testing the same type of single-point generator 200, an end cover 410 corresponding to the specification of the single-point generator 200 with the maximum power to be tested is used. The middle part of the end cover 410 is provided with a bearing chamber 411, and a bearing 412 is arranged in the bearing chamber 411. It can be understood that the number of bearings 412 can be one or two, and the specific number is set according to actual needs.
[0041] The first coupling member 420 is arranged between the end cover 410 and the non-bearing end of the single-point generator 200, and is used to connect the end cover 410 and the frame of the single-point generator 200 together during the test.
[0042] The connecting shaft 430 can match various specifications of the single support generator 200. For example, when testing the same type of single support generator 200, the connecting shaft 430 corresponding to the specification of the single support generator 200 with the maximum power to be tested is used to ensure that the matching rotational driving force can be transmitted. During assembly, the connecting shaft 430 is arranged in the bearing 412.
[0043] The second coupling member 440 is arranged between the connecting shaft 430 and the non-bearing end of the single support generator 200, and is used to connect the rotor shaft of the single support generator 200 and the connecting shaft 430 together during testing.
[0044] The third coupling member 450 is arranged between the end cover 410 and the prime mover 300, and is used to connect the prime mover 300 and the connecting shaft 430 together. The third coupling member 450 can also match various specifications of the single support generator 200. For example, when testing the same type of single support generator 200, the third coupling member 450 corresponding to the specification of the single support generator 200 with the maximum power to be tested is used to ensure that the matching rotational driving force can be transmitted. During testing, the rotational driving force generated by the prime mover 300 is transmitted to the connecting shaft 430 through the third coupling member 450. Since the first coupling member 420 fixes the end cover 410 and the stationary part of the single support generator 200 together, at this time the connecting shaft 430 rotates relative to the end cover 410 through the bearing 412, and in turn drives the rotor shaft of the single support generator 200 to rotate through the second coupling member 440, so that the rotor of the single support generator 200 rotates finally.
[0045] The measurement assembly 500 is used to measure the electrical performance of the single support generator 200, such as voltage, current, power, and power factor.
[0046] In this embodiment, since the end cover 410, the connecting shaft 430, and the third coupling member 450 can match various specifications of the single support generator 200, when testing single support generators 200 of different specifications, only the single support generator 200 and the first coupling member 420 and the second coupling member 440 matched with the single support generator 200 need to be replaced, without the need to replace the end cover 410, the connecting shaft 430, and the third coupling member 450, thereby improving the testing efficiency and reducing the testing cost.
[0047] In some optional embodiments, as shown in Figure 5 The first coupling member 420 includes a first connecting flange, and the first connecting flange connects the end cover 410 and the base of the single support generator 200 together through fasteners.
[0048] In some optional embodiments, as shown in Figure 6As shown, the second coupling member 440 includes a second connecting flange, and the second connecting flange connects the rotor shaft of the single-support generator 200 and the connecting shaft 430 together through fasteners.
[0049] In some optional embodiments, such as Figure 1 As shown, the third coupling member 450 includes a coupling that connects the output shaft of the prime mover 300 and the connecting shaft 430 together through fasteners.
[0050] In some optional embodiments, such as Figure 1 As shown, there are multiple couplings, and the multiple couplings are cascaded together.
[0051] In some optional embodiments, such as Figure 1 As shown, the measurement component 500 includes a speed torque sensor, which is used to obtain the output power of the single-support generator 200.
[0052] In some optional embodiments, the speed and torque sensor is connected in series between any adjacent couplings.
[0053] In some optional embodiments, in order to provide an upward supporting force for the speed torque sensor and reduce the influence of the position swing on the measurement accuracy, as shown in FIG. Figure 1 As shown, a support base 110 is provided between the speed and torque sensor and the support platform 100 .
[0054] In some optional embodiments, in order to reduce transmission vibration, the coupling is an elastic coupling.
[0055] In some optional embodiments, such as Figure 1 As shown, a mounting base 120 is provided between the support platform 100 and the single-support generator 200. The single-support generator 200 is stably fixed to the support platform 100 through the mounting base 120. It should be understood that since the center height and foot installation dimensions of single-support generators 200 of different powers are different, mounting bases 120 of different heights need to be designed when testing single-support generators 200 of different powers.
