Description

Technical Field

[0001] This invention relates to the field of electrical technology, and more specifically to an auxiliary device for collecting high-temperature information of electrical appliances and a power distribution cabinet. Background Technology

[0002] In use, it is often necessary to consider the operating status of electrical appliances in order to take appropriate measures. The operating status of the appliance is, for example, the temperature at which the appliance is located. The appropriate measures to take are, for example, maintenance or suspension of operation when the appliance is in a high-temperature state. Electronic gas sensors can be used to understand the high-temperature condition of the appliance, because there are often plastic parts inside the appliance. At high temperatures, the plastic parts will emit some odors. The condition of the appliance or its aging can be judged based on the temperature.

[0003] Currently, there are no auxiliary devices for collecting high-temperature information from electrical appliances. For example, when collecting high-temperature information from electrical appliances, electronic gas sensors are used for direct detection. Sometimes, the odor emitted by electrical appliances at high temperatures is very faint, making it difficult for electronic gas sensors to detect, resulting in inaccurate detection and inconvenience in use. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned shortcomings by providing an auxiliary device and distribution cabinet for collecting high-temperature information of electrical appliances that can sensitively detect and is easy to use.

[0005] The technical solution of the electrical appliance high-temperature information acquisition auxiliary device of the present invention is as follows: an electrical appliance high-temperature information acquisition auxiliary device, characterized in that: it includes a plastic block, the plastic block being made of plastic that easily produces irritating gases at high temperatures; one side of the plastic block has a mounting part, the mounting part being a part installed on and fixed to the side of the electrical appliance; the plastic block has a cavity with two ports, namely an air inlet and an air outlet; it includes an electronic odor sensor, the electronic odor sensor having a detection contact, the detection contact being inserted into the air outlet and fixedly connected; the electronic odor sensor is connected to an alarm device.

[0006] Furthermore, the air inlet has a constricted structure.

[0007] Furthermore, the cavity contains multiple fins.

[0008] Furthermore, a fan is installed inside the cavity, and the fan blows air towards the air outlet. There is also an air outlet channel on the plastic block that connects to the cavity. The opening of the air outlet channel inside the cavity is between the fan and the air outlet, and the diameter of the air outlet channel is 1 / 3 of the diameter of the cavity.

[0009] Furthermore, the mounting part also has a heat-conducting plate, and the cavity is surrounded by a heat-conducting ring. The heat-conducting ring and the heat-conducting plate are an integral metal sheet.

[0010] Furthermore, the cavity also contains a container for plastic powder.

[0011] Furthermore, there is a cover on the air inlet.

[0012] The technical solution of the power distribution cabinet of the present invention is implemented as follows: a power distribution cabinet includes a power distribution cabinet body, a cabinet cavity inside the power distribution cabinet body, an installation plate installed inside the cabinet cavity, and electrical components installed on the installation plate. The power distribution cabinet body also includes a front door, and a cabinet door is installed at the door. The feature is that an electrical high temperature information acquisition auxiliary device is also installed on the electrical components, and the electrical high temperature information acquisition auxiliary device is the aforementioned electrical high temperature information acquisition auxiliary device.

[0013] The beneficial effects of this invention are that such an electrical high-temperature information acquisition auxiliary device and distribution cabinet have the advantages of sensitive detection and ease of use. Attached Figure Description

[0017] The present invention will now be further described with reference to the accompanying drawings.

[0018] like Figure 1 , 2As shown, an auxiliary device for collecting high-temperature information of electrical appliances is characterized by: a plastic block 1, which is made of plastic that easily produces irritating gases at high temperatures; a mounting part 11 on one side of the plastic block, which is installed on and fixed to the side of the electrical appliance; a hole 12 on the plastic block, which has two ports, namely an air inlet 13 and an air outlet 14; an electronic odor sensor 2, which has a detection contact 21 that extends into the air outlet and is fixedly connected; and an alarm device 3 connected to the electronic odor sensor.

[0019] The mounting part, for example, has mounting screw holes on the plastic block and also includes a mounting plate with mounting holes. The mounting screw holes and mounting holes correspond to each other, and connecting bolts are connected through the mounting screw holes and mounting holes. The mounting part of the present invention is the part that is installed on the electrical appliance during use. For example, a cable is installed on the above-mentioned mounting part, that is, the above-mentioned plastic block and mounting plate hold the cable. In short, the mounting part only needs to be able to fix the high temperature information acquisition auxiliary device of this electrical appliance on the electrical appliance.

[0020] The electronic odor sensor, also known as an electronic nose or odor scanner, is a novel instrument for rapid detection developed in the 1990s. It uses specific sensors and pattern recognition systems to quickly provide overall information about the sample being tested.

[0021] The high-temperature information acquisition auxiliary device for electrical appliances of the present invention adopts the above technical solution. When in use, it is installed on the electrical appliance, such as on the cable, or on the circuit breaker or transformer. During the use of the electrical appliance, the appliance generates heat. When the electrical appliance reaches a certain temperature, the heat is transferred to the high-temperature information acquisition auxiliary device. The plastic block of the device will emit a pungent odor at high temperature. This pungent odor is captured by the electronic odor sensor. The electronic odor sensor can sensitively obtain attention information and transmit this information to the alarm device, which then issues an alarm or sends a command.

[0022] The alarm device mentioned above is, for example, an alarm bell or an alarm light.

[0023] The cavities help collect odorous gases produced on the plastic block.

[0024] Furthermore, there is a constriction structure 15 at the air inlet.

[0025] This design also has the advantage that the odorous gases produced by the plastic block are less likely to escape from the air inlet, making them easier for the electronic odor sensor to detect.

[0026] Furthermore, the cavity contains multiple fins 16.

[0027] This design makes it more conducive to generating odorous gases.

[0028] Furthermore, a fan 17 is installed inside the cavity, and the fan blows air towards the air outlet. There is also an air outlet channel on the plastic block that connects to the cavity. The opening of the air outlet channel inside the cavity is between the fan and the air outlet, and the diameter of the air outlet channel is 1 / 3 of the diameter of the cavity.

[0029] Furthermore, the mounting part also has a heat-conducting plate 18, and the cavity is surrounded by a heat-conducting ring 19. The heat-conducting ring and the heat-conducting plate are an integral metal sheet.

[0030] This design makes it easier for the appliance to transfer its own heat to the high-temperature information acquisition auxiliary device, making it easier for the high-temperature information acquisition auxiliary device to generate odorous gas, thus improving the sensitivity of the high-temperature information acquisition auxiliary device.

[0031] Furthermore, the cavity also contains a container 110 for holding plastic powder.

[0032] This invention is designed such that when some odor-producing plastic powder is placed in the holding cavity during use, it is even easier to generate odorous gas.

[0033] Furthermore, there is a cover plate 111 on the air inlet.

[0034] The present invention is designed such that a cover plate can be closed before use to prevent the powder placed in the holding cavity from escaping, and also to prevent foreign objects from falling into the cavity.

[0035] The technical solution of the power distribution cabinet of the present invention is implemented as follows: a power distribution cabinet includes a power distribution cabinet body, the power distribution cabinet body has a cabinet cavity, an installation plate is installed in the cabinet cavity, and electrical components are installed on the installation plate. The power distribution cabinet body also includes a front door, and a cabinet door is installed at the door. The feature is that an electrical high temperature information acquisition auxiliary device is also installed on the electrical components, and the electrical high temperature information acquisition auxiliary device is any one of the electrical high temperature information acquisition auxiliary devices in claims 1-8 above.

[0036] This invention has the advantage of being more sensitive in detecting the usage status of electrical components on the power distribution cabinet.

[0037] The electrical components mentioned above include, for example, circuit breakers, cables, and transformers.

[0038] Furthermore, the electrical appliance has plastic parts, and the plastic block of the electrical high-temperature information acquisition auxiliary device installed on this electrical appliance is made of the same material.

[0039] The electrical appliance has plastic parts, such as the plastic shell and handle.

[0040] This invention has the advantage of simultaneously triggering alarms from the electrical appliance's high-temperature information collection auxiliary device when an impending accident (aging and deterioration of plastic parts) occurs. For example, when a change occurs in the plastic parts of the appliance, the high-temperature information collection auxiliary device will simultaneously issue an alarm.

[0041] Furthermore, the electrical appliance has plastic parts, and the plastic powder placed inside the container is of the same material.

[0042] The principle is the same as above.

[0043] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of the present invention.
