Description

Technical Field

[0001] The present application relates to the technical field of intelligent circuit breakers, and in particular to a split installation housing, a circuit breaker, and a circuit breaker installation method. Background Art

[0002] The leakage circuit breaker is used to protect people from indirect contact, and can also be used to prevent fire hazards caused by ground fault currents caused by equipment insulation damage. It can also be used to distribute electrical energy and protect lines and power equipment from overload and circuit breaking. Existing leakage circuit breakers generally have a leakage transformer built in. The shape of the leakage transformer is generally elliptical. Multiple circuit breakers generally use a leakage transformer to connect together. For easy installation, a soft wire is passed through the leakage transformer to obtain a leakage signal.

[0003] Although the method of using soft wires to pass through the leakage transformer is easy to install, due to the hardness of the soft wires themselves, there will be large differences in the position of the leakage transformer, which will inevitably cause accuracy problems. If hard conductors are used instead of soft wires, the accuracy problem can be effectively reduced, but this method will make the installation more complicated and difficult, and the shell structure will be more complicated accordingly.

DETAILED DESCRIPTION

[0048] The following is combined with Figure 1 -Attached Fig.13 , further details of this application are given.

[0049] like Figure 1 As shown, the present application discloses a split installation housing 1, comprising a first housing 2 and a second housing 3 that are plugged into each other. The first housing 2 and the second housing 3 are both made of insulating materials, and the plug-in fit between the two can be achieved through interference fit between a number of columns and holes, or after the clearance between the columns and holes is matched, bolts and other components can be used to improve the installation stability.

[0050] like Figure 1 and Figure 2 As shown, the first housing 2 includes a main body 21 and a separator 22. The main body 21 is provided with a first through hole 211 for the leakage transformer 72 to pass through. An opening position 212 corresponding to the separator 22 is provided at one end of the main body 21. The opening position 212 is connected to the first through hole 211. A mounting hole 213 is provided at a position of the main body 21 corresponding to the opening position 212. The separator 22 is provided with a mounting column 221 that is plugged into and matched with the mounting hole 213.

[0051] The first housing 2 is a split arrangement, and its corresponding main body 21 and separation 22 can be separated and connected. When the separation 22 is not installed on the main body 21, the main body 21 will have an opening position 212 on the notch of the separation 22. In other words, when the separation 22 and the main body 21 are installed together, the opening position 212 does not exist, and the first housing 2 has the same appearance as the subsequent second housing 3.

[0052] The separation piece 22 is located outside the first housing 2. When the separation piece 22 is not installed, one side of the first housing 2 is a concave structure.

[0053] At the same time, the first through hole 211 is used for the leakage transformer 72 to pass through. When the separator 22 is not installed, the first through hole 211 is in an open state because the first through hole 211 is connected to the opening 212. When the separator 22 is installed, the separator 22 will block the first through hole 211 so that the first through hole 211 becomes a closed state.

[0054] In the embodiment of the present application, the mounting column 221 on the separation component 22 is a cylinder, and the mounting hole 213 on the main component 21 is a circular hole. The mounting column 221 can be directly inserted into the mounting hole 213 for installation and fixation, or it can be installed by bolts, expansion screws and other mounting parts after the mounting column 221 and the mounting hole 213 are clearly matched.

[0055] Specifically, the mounting holes 213 are located on both sides of the opening 212 , and the mounting posts 221 are integrally provided on both sides of the separation piece 22 .

[0056] An accommodating cavity 4 is provided between the main body 21 and the separating member 22, and the accommodating cavity 4 is used to accommodate and install the hard conductor 71. When the hard conductor 71 is installed in the accommodating cavity 4, one end of the hard conductor 71 corresponds to the opening position 212. The hard conductor 71 corresponds to the soft wire, and is used as a conductive element for transmitting electrical signals.

[0057] The second housing 3 is provided with a second through hole 31 for the leakage transformer 72 to pass through. When the first housing 2 and the second housing 3 are mounted together, the positions of the first through hole 211 and the second through hole 31 correspond to each other.

[0058] like Figure 1 and Figure 3As shown, through the above arrangement, the first housing 2 of the split installation housing 1 is a detachable structure. When the separation piece 22 is removed, an open structure of the opening position 212 appears, and a part of the hard conductor 71 will protrude from the opening position 212 after being installed in the first housing 2. When the split installation housing 1 is installed and matched with other housings, it is only necessary to pass one end of the hard conductor 71 through the opening position 212 from the hole in the middle of the leakage mutual inductor 72, and the opening size of the opening position 212 is generally larger than the elliptical leakage mutual inductor. The wide side hole spacing of the device 72 is set, so that when the hard conductor 71 passes through the leakage transformer 72, it will not be blocked by the leakage transformer 72. When the hard conductor 71 passes through the corresponding position, the leakage transformer 72 is located in the first through hole 211 connected to the opening position 212. Then, the separation piece 22 is installed on the main body 21 to block the leakage transformer 72 again. Finally, the second shell 3 is plugged into the first shell 2 to complete the installation process. In this way, the installation efficiency is improved and the installation process is simplified when facing the hard conductor 71.

[0059] In some other embodiments, the first shell 2 and the second shell 3 are both provided with a collection plate through hole 5 along the thickness direction thereof.

[0060] The through holes are provided to facilitate the passage of the voltage collection board 75 and the current-temperature collection board 76 which are matched with the hard conductor 71 for detection in the split installation housing 1 after subsequent installation.

[0061] like Figure 4 and Figure 5 As shown, the present application also discloses a circuit breaker, including the above-mentioned split installation housing 1, and also including a bottom installation housing 6 and a detection component 7, wherein the detection component 7 includes a hard conductor 71 and a leakage transformer 72, the hard conductor 71 is arranged in the split installation housing 1 and the bottom installation housing 6, and the leakage transformer 72 is sleeved on the hard conductor 71.

[0062] The bottom mounting shell 6 comprises a third shell 61 and a fourth shell 62 which are plugged into each other. The third shell 61 is provided with a third through hole 611 for the leakage transformer 72 to pass through. The third shell 61 and the first shell 2 are in abutment with each other.

[0063] First of all, it should be noted that this circuit breaker refers to multi-p circuit breakers such as 2p, 3p, 4p, etc. above 1p.

[0064] In addition to the split installation housing 1, the circuit breaker also includes a bottom installation housing 6. Compared with the split installation housing 1, the bottom installation housing 6 is different in that the corresponding third housing 61 and fourth housing 62 are both inseparable complete housings.

[0065] The detection component 7 is a detection device for detecting various electrical signals and other related signals in the circuit breaker. The hard conductor 71 serves as a medium for providing wiring and electrical signal transmission. The leakage transformer 72 is sleeved on the hard conductor 71 to detect the leakage current 76.

[0066] Each installation housing, whether the bottom installation housing 6 or the split housing, is provided with a complete set of detection components 7, wherein the leakage transformer 72 is shared by multiple installation housings.

[0067] The third housing 61 and the fourth housing 62 included in the bottom mounting housing 6 are mounted and fixed by the corresponding mounting structure which is the same as the first housing 2 and the second housing 3. When the bottom mounting housing 6 and the split mounting housing 1 are mounted, the third housing 61 and the first housing 2 are in contact with each other, while the fourth housing 62 and the second housing 3 are separated on both sides.

[0068] The third housing 61 is provided with a third through hole 611 for the leakage transformer 72 to pass through, while the fourth housing 62 has no corresponding through hole, because when the circuit breaker is installed, one side of the circuit breaker is fixed to the fourth housing 62, so the leakage transformer 72 must be inside the fourth housing 62 and will not pass through the fourth housing 62. Multiple transformers are cumulatively installed with multiple split installation housings 1, so when it is uncertain which split installation housing 1 is on the other side, it is necessary to ensure that the first housing 2 and the second housing 3 corresponding to each split installation housing 1 are provided with through holes for the leakage transformer 72 to pass through.

[0069] During installation, first, the leakage transformer 72 is sleeved on the hard conductor 71, and the hard conductor 71 is installed on the fourth shell 62, the third through hole 611 of the third shell 61 is aligned with the leakage transformer 72 and passed through, and then the third shell 61 and the fourth shell 62 are plugged and installed together, and then the opening position 212 in the first shell 2 of the separate installation shell is aligned with the hole position of the leakage transformer 72 protruding from the third shell 61 and moved until the hard conductor 71 on the third shell 61 passes through the hole position of the leakage transformer 72, and then the installation of the split installation shell 1 is completed through the above-mentioned installation method of the split installation shell 1, thereby obtaining a complete or partially complete circuit breaker structure.

[0070] like Figure 4 As shown, in other embodiments, the circuit breaker includes a split installation housing 1 and a bottom installation housing 6, and the third housing 61 and the first housing 2 are fixedly connected by a mounting member.

[0071] If the circuit breaker is a 2p circuit breaker, it includes a split mounting housing 1 and a bottom mounting housing 6. The mounting method is as shown above, and the split mounting housing 1 and the bottom mounting housing 6 are fixedly connected by mounting members between the third housing 61 and the first housing 2 that abut against each other. The mounting members may include commonly used bolts for fixing, or a T-shaped rail may be provided on the outside of the third housing 61 or the first housing 2, and a T-shaped block may be provided on the other housing for installation and fixing by sliding. In the embodiment of the present application, the mounting members are rivets.

[0072] like Figure 6 As shown, in other embodiments, the circuit breaker includes a bottom mounting shell 6 and a plurality of split mounting shells 1, wherein the split mounting shells 1 are all located on one side of a third shell 61 in the bottom mounting shell 6, the third shell 61 of the bottom mounting shell 6 and the first shell 2 corresponding to the split mounting shell 1 adjacent to the bottom mounting shell 6 are fixedly connected through mounting parts, and adjacent split mounting shells 1 are fixedly connected through mounting parts between the first shell 2 and the second shell 3 respectively.

[0073] If the circuit breaker is a 3p, 4p or other circuit breaker, the circuit breaker includes a bottom mounting housing 6 and a plurality of split mounting housings 1. The installation steps of the bottom mounting housing 6 and the first split mounting housing 1 adjacent to the bottom mounting housing 6 remain unchanged, while the second split mounting housing 1 is installed close to the second housing 3 of the first split mounting housing 1. The overall installation process is the same as the above-mentioned method, and the hard conductor 71 in the first housing 2 of the subsequent split mounting housing 1 is also installed by translation through the protruding leakage transformer 72. Because multiple mounting housings share one leakage transformer 72, in order to achieve installation, the plurality of split mounting housings 1 are all located on one side of the third housing 61, and the fourth housing 62 remains at the outermost position.

[0074] like Figure 7 and Figure 8 As shown, in other embodiments, the detection component 7 also includes a current transformer 73, a temperature probe 74, and a terminal block 77, and the circuit breaker also includes a collection component, and the collection component includes a voltage collection board 75 and a current-temperature collection board 76.

[0075] The hard conductor 71 includes a connection terminal 711 , a detection terminal 712 and a terminal body 713 along the length direction. The detection terminal 712 is used for mounting the current transformer 73 and the leakage transformer 72 . The temperature probe 74 is fixedly connected to the detection terminal 712 .

[0076] The terminal 711 is a conductive metal sheet, and a wiring hole is provided on the terminal 711 for connecting the wire. The detection terminal 712 is used to connect or fix the corresponding detection elements, such as the current transformer 73, the leakage transformer 72, the temperature probe 74, etc. The terminal body 713 is subsequently used to connect the terminal block 77, and is also used for connecting the wire.

[0077] The voltage acquisition board 75 is electrically connected to the detection end 712 to collect voltage detection signals, and the current-temperature acquisition board 76 is electrically connected to the temperature probe 74, the current transformer 73 and the leakage transformer 72 respectively to collect temperature detection signals, current detection signals and leakage detection signals.

[0078] The wiring seat 77 is sleeved on the terminal body 713 , and the terminal body 713 corresponds to the opening position 212 . The separation piece 22 and the second housing 3 are both provided with a placement slot 8 corresponding to the terminal body 713 .

[0079] When the terminal block 77 is sleeved on the terminal body 713, the terminal body 713 is in the open position 212, and after the separator 22 is installed on the main body 21, the separator 22 and the placement groove 8 on the second shell 3 cooperate to generate a space for the terminal block 77 to be accommodated and fixed.

[0080] In some other embodiments, both the third shell 61 and the fourth shell 62 are provided with a collection board through hole 5 .

[0081] The collection board through holes 5 on the third housing 61 and the fourth housing 62 are used to allow the voltage collection board 75 and the current-temperature collection board 76 to pass through when the circuit breaker is installed.

When the hard conductor 71 passes to the corresponding position, the leakage transformer 72 is located in the first through hole 211 connected to the opening position 212. Then, the separation component 22 is installed on the main body 21 to block the leakage transformer 72 again. Finally, the second shell 3 is plugged into the first shell 2 to complete the installation process.

[0089] In other embodiments, if the circuit breaker includes a bottom installation housing 6 and a plurality of split installation housings 1, after the second housing 3 is plugged and installed with the first housing 2, the following steps are also included:

[0093] If the circuit breaker is a 3p, 4p or other circuit breaker, the circuit breaker includes a bottom mounting housing 6 and a plurality of split mounting housings 1. The installation steps of the bottom mounting housing 6 and the first split mounting housing 1 adjacent to the bottom mounting housing 6 remain unchanged, while the second split mounting housing 1 is installed close to the second housing 3 of the first split mounting housing 1. The overall installation process is the same as the above-mentioned method, and the hard conductor 71 in the first housing 2 of the subsequent split mounting housing 1 is also installed by translation through the protruding leakage transformer 72. Because multiple mounting housings share one leakage transformer 72, in order to achieve installation, the plurality of split mounting housings 1 are all located on one side of the third housing 61, and the fourth housing 62 remains at the outermost position.
