Description

Technical Field

[0001] The present invention relates to the technical field of center-mounted switch cabinets, and in particular to a safety monitoring system for monitoring center-mounted switch cabinets in transformer substations. Background Art

[0002] The full name of the center switchgear is metal armored center removable switchgear. It is a high-voltage power distribution device with a maximum working voltage of 3.6 / 7.2 / 12kV. It is an indoor complete power distribution device for three-phase AC 50Hz single busbar segmentation system or double busbar segmentation system. It is used to receive and distribute 3.6-12kV network power and implement control, protection, monitoring and measurement of power circuits. The center switchgear is mainly used for power plants, power transmission of small and medium-sized generators, power reception and transmission of secondary substations of power systems, and power distribution of industrial and mining enterprises and institutions.

[0003] When the existing safety monitoring system for monitoring the central switch cabinet in the substation is in use, since the safety monitor is generally fixed to the central switch cabinet by bolts, the staff need to use tools such as screwdrivers or wrenches to dismantle the monitor for maintenance, which is very troublesome for the staff and cannot conveniently perform maintenance on the monitor. Summary of the invention

[0004] The present invention aims to provide a safety monitoring system for monitoring a central switch cabinet in a substation to solve the above-mentioned technical problems. By providing an installation device for fixing the monitor, the staff can quickly disassemble the monitor, thereby improving the efficiency of the monitor maintenance.

[0005] In order to solve the above technical problems, the present invention provides a safety monitoring system for monitoring a central switch cabinet in a substation, comprising a switch cabinet and a monitor electrically connected to the switch cabinet; the safety monitoring system also includes an installation device; the installation device includes a base and a movable part clamped with the base; wherein: the base is fixedly arranged on the outer wall of the switch cabinet; the monitor is placed on the base and fixed by the movable part.

[0006] In the above scheme, by providing a mounting device for fixing the monitor, the fixing method of fixing the monitor to the switch cabinet by bolts is cleverly avoided. The monitor only needs to be placed on the base and fixed to the switch cabinet through movable parts. The base and the movable parts are connected by a snap-on method, that is, they can be directly disassembled without external tools. The staff does not need to use external tools when disassembling and repairing the monitor, which allows the staff to quickly disassemble the monitor and effectively improve the efficiency of the maintenance of the monitor.

[0007] Furthermore, the base includes a support platform and a support block; wherein: the support platform is fixedly arranged on the outer wall of the switch cabinet for placing the monitor; the support block is fixedly connected to the support platform; a card slot is opened on the support block, and a protrusion for clamping the movable part is arranged in the card slot.

[0008] In the above scheme, the movable part can be inserted into the slot of the support block, and the size of the insertion part of the movable part is adapted to the slot, and the protrusion set in the slot can limit the movement of the movable part. When installing, the movable part only needs to be pressed into the slot with force, so that the protrusion is tightly engaged with the insertion part of the movable part to achieve the connection between the support block and the movable part.

[0009] Furthermore, in order to better insert the movable part into the card slot, the protrusion can be made of a material with a certain elasticity, such as hard rubber; the movable part insertion part can also be made of a material with a certain elasticity, such as hard rubber.

[0010] It should be noted that a protective member of a certain height, namely a fence, can be provided on the edge of the support platform to limit the position of the monitoring instrument and consolidate the connection between the support platform and the monitoring instrument.

[0011] Further, the slot is arranged as a through hole, and the protrusion is arranged on the inner surface of the through hole.

[0012] In the above scheme, the card slot is set as a through hole to allow the movable part to have more room for movement, and the plug-in part can adjust the plug-in depth according to the size of the monitor model, ensuring that the fixed space formed by the connection between the movable part and the base can be more compatible with the monitor, thereby consolidating the connection relationship between the monitor and the installation device.

[0013] Furthermore, the movable part includes a movable plate, a movable rod and a movable block; wherein: the movable block is fixedly connected to the movable plate; a through hole is opened on the movable block; the movable rod includes a rod body, a clamping block and a locking piece; after the rod body passes through the through hole, one end of the movable rod is fixedly connected to the clamping block, and the other end of the movable rod is detachably connected to the locking piece; when the monitor is placed on the base, the movable part covers the top of the monitor through the movable plate, and is inserted into the clamping slot through the rod body; the rod body is rotated to make the clamping block engage with the protrusion.

[0014] In the above scheme, the size of the card block in one direction can be slightly smaller than the space formed by the protrusion and the inner wall of the card slot, so that the movable rod can be smoothly inserted into the card slot; and the card block has a card connection portion facing outward in another direction, such as setting the card block to a T-shaped structure. When the movable rod is inserted into the card slot, the card connection portion can be engaged with the protrusion by rotating the rod body. At this time, the movable rod cannot be pulled out of the card slot, so that the movable part and the base form a card connection relationship. When the movable part is connected to the base, the rod body tends to move downward due to the effect of gravity. On the one hand, the locking member can prevent the rod body from falling, and on the other hand, the bottom of the card slot can support the rod body to ensure the stability of the installation device.

[0015] It should be noted that the rod body only passes through the through hole, and its horizontal position is fixed, but it can move freely in the vertical direction and can rotate. After the rod body passes through the through hole, the locking piece is detachably connected to the movable rod, and its connection method can be a threaded connection, which is used to restrict the rod body in the through hole to prevent the rod body from detaching.

[0016] It should be noted that in the above solution, it is also feasible to set the card slot as a through hole.

[0017] Furthermore, the movable member further comprises a spring; after the rod body passes through the through hole, the spring is sleeved on the rod body between the movable block and the locking member.

[0018] In the above solution, the setting of the spring can further prevent the rod from falling. After the movable part and the base are connected, one end of the spring abuts against the locking part and the other end abuts against the movable block, and has a tendency to rebound. That is, the spring can give the rod an upward force through the locking part, so that the clamping block at the bottom of the rod is tightly clamped on the protrusion, thereby stabilizing the connection between the movable part and the base.

[0019] Furthermore, the installation device further comprises a slide slot and a first slider, wherein: the slide slot is vertically fixedly arranged on the outer wall of the switch cabinet, and the first slider is fixedly arranged on the movable member; the movable member is clamped on the slide slot through the first slider. It should be noted that the first slider can be arranged on the movable plate.

[0020] In the above solution, when disassembling the monitor, the staff only needs to remove the movable part from the base, and then slide the first slider fixed to the movable part on the slide groove, so that a larger operating space can be formed between the movable part and the base, which is convenient for disassembling the monitor. The setting of the slide groove and the first slider can limit the movable part to a certain position, avoid the situation where some parts of the movable part are lost during the disassembly process, and improve the integrity of the installation device.

[0021] Furthermore, the mounting device also includes a second slider, which is fixedly arranged on the base; the base is clamped on the slide groove through the second slider.

[0022] In the above solution, the connection between the base and the slide groove is established by the second sliding block, which can effectively improve the integrity of the installation device.

[0023] Furthermore, the installation device also includes a latch pin, and the slide groove is provided with limit holes at equal intervals; the latch pin is inserted into the limit hole to clamp the second slide block.

[0024] In the above scheme, the setting of the limit hole and the pin can make the installation height of the installation device adjustable, that is, in actual application, by pushing the base upwards, the base is placed in a suitable position, and the pin is inserted into the first limit hole exposed outside the slide groove. At this time, the base is released, and the pin will abut under the second slider, thereby limiting the second slider from sliding downward on the slide groove, thereby fixing the position of the base and effectively improving the flexibility of the installation of the installation device.

[0025] Furthermore, the monitor includes a shell, a monitoring circuit, a display module and a button module; wherein: the monitoring circuit is fixedly arranged inside the shell and is electrically connected to the switch cabinet; the display module is fixedly arranged on the front of the shell, and its input end is electrically connected to the output end of the monitoring circuit; the button module is fixed on the front of the shell, and its output end is electrically connected to the input end of the monitoring circuit; the shell is placed on a base and fixed by movable parts.

[0026] In the above scheme, the monitoring circuit is used to monitor the switch cabinet in real time and send the monitoring data to the display module for display; the button module is used to control the monitor, and the corresponding function instructions can be sent to the monitoring circuit through the button module to make the monitoring circuit produce corresponding actions, thereby realizing the control of the monitor.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-Figure 3 This embodiment proposes a safety monitoring system for monitoring a central switch cabinet 1 in a substation, comprising a switch cabinet 1 and a monitor 2 electrically connected to the switch cabinet 1; the safety monitoring system also includes an installation device 3; the installation device 3 includes a base 31 and a movable part 32 clamped with the base 31; wherein: the base 31 is fixedly arranged on the outer wall of the switch cabinet 1; the monitor 2 is placed on the base 31 and fixed by the movable part 32.

[0034] In this embodiment, by providing a mounting device 3 for fixing the monitor 2, the fixing method of fixing the monitor 2 to the switch cabinet 1 by bolts is cleverly avoided. The monitor 2 only needs to be placed on the base 31 and fixed to the switch cabinet 1 by the movable part 32. The base 31 and the movable part 32 are connected by a snap-fit ​​method, that is, they can be directly disassembled without external tools. The staff does not need to use external tools when disassembling and repairing the monitor 2, which allows the staff to quickly disassemble the monitor 2, effectively improving the efficiency of the maintenance of the monitor 2.

[0035] In one embodiment, the base 31 includes a support platform 311 and a support block 312; wherein: the support platform 311 is fixedly arranged on the outer wall of the switch cabinet 1, and is used to place the monitor 2; the support block 312 is fixedly connected to the support platform 311; a card slot is opened on the support block 312, and a protrusion for clamping the movable part 32 is arranged in the card slot.

[0036] In this embodiment, the movable member 32 can be inserted into the slot of the support block 312. At this time, the size of the insertion part of the movable member 32 is adapted to the slot, and the protrusion provided in the slot can limit the movement of the movable member 32. During installation, the movable member 32 only needs to be pressed into the slot with force so that the protrusion is tightly engaged with the insertion part of the movable member 32, so that the support block 312 and the movable member 32 can be engaged.

[0037] In one embodiment, in order to better insert the movable part 32 into the card slot, the protrusion can be made of a material with a certain elasticity, such as hard rubber; the insertion part of the movable part 32 can also be made of a material with a certain elasticity, such as hard rubber.

[0038] It should be noted that a protective member of a certain height, namely a fence, may be provided on the edge of the support platform 311 to limit the position of the monitoring device 2 and consolidate the connection between the support platform 311 and the monitoring device 2 .

[0039] In one embodiment, the slot is configured as a through hole 3121 , and the protrusion is configured on the inner surface of the through hole 3121 .

[0040] In this embodiment, the card slot is set as a through hole 3121 to allow the movable part 32 to have more room for movement, and the plug-in part thereof can adjust the plug-in depth according to the size of the monitor 2, thereby ensuring that the fixed space formed by the connection between the movable part 32 and the base 31 can be more compatible with the monitor 2, thereby consolidating the connection relationship between the monitor 2 and the installation device 3.

[0041] In one embodiment, the movable member 32 includes a movable plate 321, a movable rod 322 and a movable block 323; wherein: the movable block 323 is fixedly connected to the movable plate 321; a through hole is provided on the movable block 323; the movable rod 322 includes a rod body 3221, a clamping block 3222 and a locking member 3223; after the rod body 3221 passes through the through hole, one end of the movable rod 322 is fixedly connected to the clamping block 3222, and the other end of the movable rod 322 is detachably connected to the locking member 3223; when the monitor 2 is placed on the base 31, the movable member 32 covers the top of the monitor 2 through the movable plate 321, and is inserted into the clamping slot through the rod body 3221; the rod body 3221 is rotated to make the clamping block 3222 engage with the protrusion.

[0042] In this embodiment, the size of the block 3222 in one direction can be slightly smaller than the space formed by the protrusion and the inner wall of the slot, so that the movable rod 322 can be smoothly inserted into the slot; and the block 3222 has a snap-fitting portion outward in another direction, such as setting the block 3222 to a T-shaped structure. When the movable rod 322 is inserted into the slot, the snap-fitting portion can be snap-fitted with the protrusion by rotating the rod body 3221. At this time, the movable rod 322 cannot be pulled out of the slot, so that the movable member 32 and the base 31 form a snap-fitting relationship. When the movable member 32 is connected to the base 31, the rod body 3221 tends to move downward due to the action of gravity. On the one hand, the locking member 3223 can be used to prevent the rod body 3221 from falling, and on the other hand, the bottom of the slot can support the rod body 3221 to ensure the stability of the installation device 3.

[0043] It should be noted that the rod body 3221 only passes through the through hole, and its horizontal position is fixed, but it can move freely in the vertical direction and can rotate. After the rod body 3221 passes through the through hole, the locking member 3223 is detachably connected to the movable rod 322, and its connection method can be a threaded connection, which is used to restrict the rod body 3221 in the through hole to prevent the rod body 3221 from detaching.

[0044] It should be noted that in the above solution, it is also feasible to set the card slot as the through hole 3121 .

[0045] In one embodiment, the movable member 32 further includes a spring 324 ; after the rod 3221 passes through the through hole, the spring 324 is sleeved on the rod 3221 between the movable block 323 and the locking member 3223 .

[0046] It should be noted that the locking piece 3223 can be configured as a circular block.

[0047] In this embodiment, the provision of the spring 324 can further prevent the rod 3221 from falling. After the movable member 32 is connected to the base 31, one end of the spring 324 abuts against the locking member 3223, and the other end abuts against the movable block 323, and has a tendency to rebound. That is, the spring 324 can give the rod 3221 an upward force through the locking member 3223, so that the clamping block 3222 at the bottom of the rod 3221 is tightly clamped on the protrusion, thereby stabilizing the connection between the movable member 32 and the base 31.

[0048] In one embodiment, the mounting device 3 further includes a slide groove 33 and a first slider 34; wherein: the slide groove 33 is vertically fixedly arranged on the outer wall of the switch cabinet 1, and the first slider 34 is fixedly arranged on the movable member 32; the movable member 32 is clamped on the slide groove 33 through the first slider 34. It should be noted that the first slider 34 can be arranged on the movable plate 321.

[0049] In this embodiment, when disassembling the monitor 2, the staff only needs to remove the movable part 32 from the base 31, and then slide the first slider 34 fixed to the movable part 32 on the slide groove 33, so that a larger operating space can be formed between the movable part 32 and the base 31, which is convenient for disassembling the monitor 2. The arrangement of the slide groove 33 and the first slider 34 can limit the movable part 32 to a certain position, avoid the situation where some parts of the movable part 32 are lost during the disassembly process, and improve the integrity of the installation device 3.

[0050] In one embodiment, the mounting device 3 further includes a second slider, which is fixedly disposed on the base 31 ; the base 31 is clamped on the slide groove 33 via the second slider.

[0051] In this embodiment, the connection between the base 31 and the slide groove 33 is established by the second sliding block, which can effectively improve the integrity of the installation device 3.

[0052] In one embodiment, the mounting device 3 further includes a latch pin, and the slide groove 33 is provided with limiting holes at equal intervals; the latch pin is inserted into the limiting hole to clamp the second slider.

[0053] In this embodiment, the setting of the limit hole and the pin can make the installation height of the installation device 3 adjustable, that is, in actual application, by pushing the base 31 upwards, the base 31 is placed in a suitable position, and the pin is inserted into the first limit hole exposed outside the slide groove 33. At this time, the base 31 is released, and the pin will abut under the second slider, thereby limiting the second slider from sliding downward on the slide groove 33, thereby fixing the position of the base 31, effectively improving the installation flexibility of the installation device 3.

[0054] In the above embodiment, when the monitor 2 needs to be repaired, the staff first presses the locking member 3223, and the locking member 3223 compresses the spring 324 and drives the rod body 3221 to move downward, so that there is a gap between the block 3222 and the protrusion of the card slot. At this time, the rod body 3221 is rotated, and the block 3222 is rotated to an angle that can be disengaged from the card slot. Then the staff releases the locking member 3223, and the locking member 3223 is pushed upward by the spring 324, so that the block 3222 is separated from the support block 312, so that the movable plate 321 loses its limit, and the staff can move the movable plate 321 away from the monitor 2, so that the staff can easily disassemble and repair the detector without using tools.

[0055] In one embodiment, the card slot can be set as a through hole 3121, and the card block 3222 can be rotatably connected to the rod body 3221. When the staff presses the locking member 3223, the card block 3222 will pass through the card slot from the through hole 3121 under the push of the rod body 3221. At this time, the card block 3222 can be selected to rotate the card block 3222 to an angle that can be detached from the card slot. Then the staff releases the locking member 3223, and the locking member 3223 will be pushed upward under the action of the spring 324, thereby causing the card block 3222 to detach from the support block 312, so that the movable plate 321 loses its limit, and the staff can move the movable plate 321 away from the monitor 2, so that the staff can easily disassemble the detector without using tools.

[0056] In the above embodiment, the shape of the card block 3222 is the same as the shape of the card slot (through hole 3121 ); the depth of the card slot is the same as the thickness of the card block 3222 .

[0057] In one embodiment, see Figure 1 and Figure 4 The monitor 2 includes a shell 21, a monitoring circuit 22, a display module 23 and a key module 24; wherein: the monitoring circuit 22 is fixedly arranged inside the shell 21 and is electrically connected to the switch cabinet 1; the display module 23 is fixedly arranged on the front of the shell 21, and its input end is electrically connected to the output end of the monitoring circuit 22; the key module 24 is fixed on the front of the shell 21, and its output end is electrically connected to the input end of the monitoring circuit 22; the shell 21 is placed on a base 31 and is fixed by a movable part 32.

[0058] In this embodiment, the monitoring circuit 22 is used to monitor the switch cabinet 1 in real time and send the monitoring data to the display module 23 for display; the button module 24 is used to control the monitor 2, and the corresponding function instructions can be sent to the monitoring circuit 22 through the button module 24 to make the monitoring circuit 22 generate corresponding actions, thereby realizing the control of the monitor 2.

[0059] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
