[0036] The following detailed description will further describe the present application in combination with the above drawings. DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present application will be described in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0039] In the related art, the movement of the moving contact of the change-over switch is detected by a detection component, so as to detect whether the moving contact and the stationary contact of the change-over switch are stuck together. However, when the moving contact and the stationary contact are opened or closed, the detection component is easily affected by the moving contact and the stationary contact, so that the detection result of the detection component is inaccurate.

[0040] The embodiments of the present application provide a change-over switch, which comprises a stationary contact assembly, a moving contact assembly, a connecting assembly, a detection assembly and an isolation assembly. The connecting assembly is adjustably arranged at a position. The connecting assembly is connected with the moving contact assembly to drive the moving contact assembly to move. The detection assembly is used for detecting the movement state of the connecting assembly. Since the connecting assembly is connected with the moving contact assembly, the movement state of the moving contact assembly can be detected by detecting the movement state of the connecting assembly. In this way, the detection assembly does not need to be directly arranged towards the moving contact assembly, so that the problem that the moving contact assembly easily affects the detection effect of the detection assembly caused by the direct arrangement of the detection assembly towards the moving contact assembly is solved. Moreover, the stationary contact assembly and the moving contact assembly are both isolated from the detection assembly by the isolation assembly, so that the detection assembly is not interfered by the moving contact assembly and the stationary contact assembly. In this way, the problem that the detection component of the change-over switch in the prior art is inaccurate is further solved.

[0041] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0042] Please refer to Figures 1 to 4 The embodiments of the present application provide a change-over switch 100, a meter adapter 200 and a meter device 300.

[0043] In some embodiments, the change-over switch 100 includes a relay and a contactor, etc. The change-over switch 100 has the functions of signal detection, transmission, conversion, etc.

[0044] Please refer to Figure 1 and Figure 2 In some embodiments, the meter device 300 comprises the meter adapter 200, a meter 201 and a meter box 202. The meter adapter 200 is connected with the meter 201 and the meter box 202 through copper bars respectively. The meter box 202 is used for connecting a public power supply. The change-over switch 100 of the meter adapter 200 is used for electrically connecting to a standby power supply, so as to switch from the public power supply to the standby power supply through the change-over switch 100 when the public power supply is interrupted, so as to ensure that the standby power supply can be quickly connected when the public power supply is disconnected, and ensure uninterrupted power supply.

[0045] In the use of the electric meter device 300, the contact temperature of the switch 100 is high, which easily causes abnormal adhesion between the moving contact and the static contact of the switch 100. When the standby power supply is powered, the switch is in the grid-connected state. If the public power supply is restored during the standby power supply process, the control assembly 90 needs to control the switch 100 to switch from the grid-connected state to the off-grid state. The moving contact and the static contact of the switch 100 in the off-grid state should be disconnected. However, if the moving contact and the static contact of the switch 100 are abnormally adhered, the switch 100 cannot complete the switching from the grid-connected state to the off-grid state. The standby power supply is actually in the grid-connected state. If the abnormal adhesion of the contacts of the switch cannot be found in time, it is easy to cause a conflict between the public power supply and the standby power supply, causing equipment short circuit damage.

[0046] In some embodiments, the standby power supply includes one or more of an energy storage device, a generator, and a photovoltaic device.

[0047] Optionally, the generator includes a gasoline generator, a diesel generator, and a wind power generator.

[0048] Please refer to Figure 3 and Figure 4 In some embodiments, the electric meter adapter 200 includes a switch 100 and an adapter body 101. The adapter body 101 includes a mounting shell 60 and a control assembly 90. The control assembly 90 and the switch 100 are both arranged in the mounting shell 60, and the control assembly 90 and the switch 100 are electrically connected. The switch 100 connects the electric meter 201 and the electric meter box 202 through a copper bar.

[0049] The control assembly 90 includes a control circuit board.

[0050] Please refer to Figure 5 and Figure 6 In some embodiments, the switch 100 includes a static contact assembly 10, a moving contact assembly 20, a connecting assembly 30, and a detection assembly 40. The moving contact assembly 20 has a contact position in contact with the static contact assembly 10 and a separation position separated from the static contact assembly 10. The connecting assembly 30 is connected with the moving contact assembly 20. The connecting assembly 30 is adjustably arranged to drive the moving contact assembly 20 to move to the contact position or the separation position through the connecting assembly 30. The detection assembly 40 is used to detect the movement state of the connecting assembly 30.

[0051] Since the connecting assembly 30 is connected with the moving contact assembly 20, the detection assembly 40 detects the movement state of the connecting assembly 30 to detect the movement state of the moving contact assembly 20. In this way, the detection assembly 40 does not need to be directly arranged towards the moving contact assembly, which improves the problem that the moving contact assembly 20 easily affects the detection effect of the detection assembly 40 caused by the detection assembly 40 directly facing the moving contact assembly.

[0052] Referring to Figure 5 and Figure 7 The switch includes an isolation assembly 50, the static contact assembly 10 and the moving contact assembly 20 are isolated by the isolation assembly 50 and the detection assembly 40, so that the detection assembly 40 is isolated from the moving contact assembly 20 and the static contact assembly 10, which further improves the problem of inaccurate detection of the detection assembly of the prior art.

[0053] Referring to Figure 7 In some embodiments, the switch includes a mounting shell 60; the isolation assembly 50 includes an isolation plate 51, which is arranged in the mounting shell 60 and connected with the mounting shell 60 to divide the mounting shell 60 into a first mounting space 601 and a second mounting space 602, the static contact assembly 10 and the moving contact assembly 20 are arranged in the first mounting space 601, and the detection assembly 40 is arranged in the second mounting space 602; part of the connecting assembly 30 is arranged in the second mounting space 602, and the connecting assembly 30 is connected with the moving contact assembly 20 after passing through the isolation plate 51. In the above arrangement, the mounting shell 60 is divided into the first mounting space 601 and the second mounting space 602 by the isolation plate 51, and the detection assembly 40 is arranged in the second mounting space 602, and the static contact assembly 10 and the moving contact assembly 20 are arranged in the first mounting space 601, so that the static contact assembly 10 and the moving contact assembly 20 are located in two separate spaces respectively, thereby improving the problem that the arc and the electromagnetic generated during the opening and closing of the static contact assembly 10 and the moving contact assembly 20 easily affect the detection effect of the detection assembly.

[0054] Referring to Figure 7 In some embodiments, the isolation assembly 50 further includes a sleeve 52, the isolation plate 51 has a through hole 510, and the sleeve 52 is arranged in the through hole 510 and sealingly connected with the inner wall of the through hole 510; part of the connecting assembly 30 is movably arranged in the sleeve 52. In the above arrangement, by arranging the sleeve 52, the movement of the connecting assembly 30 can be guided, and the sleeve 52 is sealingly connected with the through hole 510 of the isolation plate 51 to reduce the gap between the connecting assembly 30 and the through hole 510 of the isolation plate 51, thereby reducing the passing rate of the arc and the electromagnetic generated during the opening and closing of the static contact assembly 10 and the moving contact assembly 20, and further improving the problem that the arc and the electromagnetic generated during the opening and closing of the static contact assembly 10 and the moving contact assembly 20 easily affect the detection effect of the detection assembly.

[0055] Referring to Figure 5 and Figure 6In some embodiments, the switch includes a mounting shell 60, the static contact assembly 10, the movable contact assembly 20, the connecting assembly 30 and the detection assembly 40 are arranged in the mounting shell 60; the isolation assembly 50 includes an isolation cover 53, the detection component is arranged in the mounting shell 60, the isolation cover 53 is connected with the mounting shell 60 and covers the detection assembly 40.

[0056] In some embodiments, the length of the isolation cover 53 extends to the connecting assembly 30, the detection assembly 40 has a detection part 410, the isolation cover 53 has a communication hole 530, the communication hole 530 avoids the detection part 410 of the detection assembly 40. In the above arrangement, by arranging the isolation cover 53, the detection assembly 40 can be separated individually, so that the arrangement of other components in the mounting shell 60 is flexible; and the length of the isolation cover 53 extends to the connecting assembly 30, so that when the detection assembly 40 detects the movement state of the connecting assembly 30, the isolation cover 53 has enough length to separate the detection signal emitted by the detection part 410 of the detection assembly 40 from the static contact assembly 10 and the movable contact assembly 20, so as to reduce the influence of the static contact assembly 10 and the movable contact assembly 20 on the detection effect of the detection assembly 40, thereby improving the problem that the arc and the electromagnetic generated in the opening and closing process of the static contact assembly 10 and the movable contact assembly 20 easily affect the detection effect of the detection assembly 40.

[0057] In some embodiments, at least part of the isolation assembly 50 is made of light shielding material and / or magnetic shielding material.

[0058] Because the movable contact assembly 20 and the static contact assembly 10 generate arc in the opening and closing process, the isolation assembly 50 made of light shielding material can achieve light shielding effect, so as to improve the problem that the arc easily affects the detection effect of the detection assembly, and improve the accuracy of detection of the detection assembly. Because the movable contact assembly 20 and the static contact assembly 10 generate electromagnetic when they are in contact, the isolation assembly 50 made of magnetic shielding material can reduce the influence of the electromagnetic on the detection assembly, thereby improving the influence of the electromagnetic on the detection result of the detection assembly, and improving the accuracy of detection of the detection assembly.

[0059] In some embodiments, at least part of the isolation assembly 50 is made of metal material. The metal material has good electrical conductivity and magnetic conductivity, can effectively absorb and reflect electromagnetic waves, thereby reducing electromagnetic interference, and the light shielding effect of the metal material is good.

[0060] In some embodiments, the isolation plate 51 is made of light shielding material and / or magnetic shielding material.

[0061] In some embodiments, the isolation cover 53 is made of light shielding material and / or magnetic shielding material.

[0062] Optionally, the detection assembly 40 comprises a non-contact sensor such as an ultrasonic sensor, a photoelectric sensor, and an inductive sensor.

[0063] Referring to Figure 5 and Figure 6 In some embodiments, the detection assembly 40 comprises a photoelectric sensor 41, and the connecting assembly 30 comprises a sensing component 31 having a detection hole 310, so that when the stationary contact assembly 10 and the movable contact assembly 20 are in the contact position, the light emitted by the photoelectric sensor 41 passes through the detection hole 310, and when the stationary contact assembly 10 and the movable contact assembly 20 are in the separation position, the sensing component 31 blocks the light emitted by the photoelectric sensor 41. In the above arrangement, since the connecting assembly 30 is connected to the movable contact assembly 20, and the sensing component 31 is part of the connecting assembly 30, the movement state of the movable contact assembly 20 can be detected through the cooperation between the photoelectric sensor 41 and the sensing component 31, so that it can be determined whether the movable contact assembly 20 and the stationary contact assembly 10 are stuck together.

[0064] When the stationary contact assembly 10 and the movable contact assembly 20 are switched from the contact position to the separation position, if the stationary contact assembly 10 and the movable contact assembly 20 remain in the contact position for a predetermined period of time, and at this time the light emitted by the photoelectric sensor 41 continuously passes through the detection hole 310, it is determined that the stationary contact assembly 10 and the movable contact assembly 20 have a sticking failure, and the photoelectric sensor 41 itself sends an alarm signal.

[0065] The alarm signal includes an acoustic signal and / or a light signal.

[0066] Referring to Figure 5 and Figure 6 The photoelectric sensor 41 comprises a detection portion 410, and the detection portion 410 of the photoelectric sensor 41 is used to emit detection light.

[0067] In some embodiments, the photoelectric sensor 41 comprises a reflective photoelectric sensor. Optionally, the reflective photoelectric sensor is arranged on the mounting shell 60, and the isolation cover 53 covers the mounting shell 60; or the reflective photoelectric sensor is arranged on the isolation plate 51.
