Description

Technical Field

[0001] This application relates to disconnecting switches, and more particularly to a fuse-type disconnecting switch. Background Technology

[0002] A fuse-type disconnect switch is an electrical switchgear that combines the functions of a fuse and a disconnect switch. It provides both circuit isolation and overload and short-circuit protection, and is widely used in low-voltage power distribution systems. In the field of disconnect switch technology, in traditional technology, when an overload or short-circuit fault occurs in a fuse-type disconnect switch, the current increases sharply. When the current exceeds the rated current of the fuse element for a certain period of time, the fuse element melts rapidly due to overheating, cutting off the circuit and protecting other equipment in the circuit from damage caused by excessive current. At the same time, the disconnect switch reliably isolates the faulty circuit from the power supply, providing a safety guarantee for subsequent inspection and maintenance. However, in actual use, after the fuse-type disconnect switch is triggered, a large amount of heat is released inside the casing due to the natural cooling of the fuse element, creating a high temperature inside the switch itself. This can damage other components inside the fuse-type disconnect switch and makes it inconvenient for personnel to carry out repairs immediately upon arrival, as they must wait for the fuse-type disconnect switch to cool down.

[0007] Preferably, a heat-conducting copper sheet is fixedly connected inside the fuse-type disconnect switch body. Two heat-conducting copper sheets are provided, and both heat-conducting copper sheets are adapted to the same fan.

[0008] Preferably, the top of the protective shell is provided with an outer frame, and a dustproof net is fixedly connected inside the outer frame, the dustproof net being adapted to the protective shell.

[0009] Preferably, two fixing plates are fixedly connected to the outer side of the outer frame, and the fixing plates are internally threaded with fixing devices, which are connected to the internal threads of the protective shell.

[0010] Preferably, the temperature control mechanism includes a temperature detector, which is installed on the outside of the protective housing and inside the protective housing.

[0013] Preferably, the communication module is electrically connected to the humidity detector, the communication module is electrically connected to the temperature detector, and the communication module is electrically connected to the fan.

[0014] In summary, this application includes at least one of the following beneficial technical effects: 1. The fuse-type disconnect switch body is the main component, while the protective shell serves as the supporting foundation and integration unit. Power is supplied to other structures via a power source. Air is drawn in and blown out by a fan through an air inlet duct. The inlet of the air inlet duct faces the bottom of the fuse-type disconnect switch body, which has ventilation holes at the bottom. The fan draws in and blows out gas from inside the fuse-type disconnect switch body along with outside air through these ventilation holes. The outside cold air mixes with the fuse-type disconnect switch body and is then blown into the space created between the baffle plate, exhaust plate, and fan. The mixture is then blown out from the exhaust port of the exhaust plate. After cooling the interior of the protective shell, the airflow is released from the top due to air pressure, and the cooled airflow mixed with outside air is blown back into the fuse-type disconnect switch body. This forces the original gas inside the fuse-type disconnect switch body to be forced out and drawn in by the fan, achieving a cooling cycle. The fuse-type disconnect switch body is mounted on the protective shell using positioning rods, which also serve as supports. A fixing ring is used to secure the fuse-type disconnect switch body to the protective shell. Inside the protective shell, the positioning rod is easily inserted, increasing the contact area and enhancing stability. The bottom of the positioning rod is convex and matches the shape of the round hole inside the protective shell, ensuring a perfect fit and preventing easy detachment, thus strengthening the fixing ability. The heat-conducting copper sheet conducts and dissipates the temperature inside the fuse-type disconnect switch body, and the fan dissipates heat from the heat-conducting copper sheet. When the fan is not turned on, it can share some of the high temperature inside the fuse-type disconnect switch body. The dustproof mesh inside the outer frame protects the structure inside the protective shell, preventing debris from falling in or dust from being blown into the protective shell by the fan, which would weaken the heat dissipation effect. The fixing plate can be fixed to the protective shell with a fixing device. When cleaning or maintenance of the internal structure of the protective shell is required, the fixing device can be removed to remove the outer frame for easy maintenance. The heat dissipation mechanism can efficiently dissipate heat from the fuse-type disconnect switch body in a timely manner and is easy to disassemble and maintain. 2. The gas inside the protective housing can be detected by temperature and humidity detectors. The gas inside the protective housing originates from the inside of the fuse-type disconnect switch body. When the temperature is too high or the humidity is too high, a signal is sent to the warning light and speaker, causing the warning light to light up and the speaker to alert nearby personnel to check the equipment. When the temperature detector detects a high temperature or the humidity detector detects a high humidity, a signal is sent to the fan to make it run at a higher efficiency. When the temperature or humidity is normal, the fan runs at a low energy efficiency. The temperature control mechanism can automatically adjust the fan's operating intensity according to the current state, achieving automated heat dissipation. At the same time, it further enhances the heat dissipation capacity and saves energy costs. 3. The current inside the fuse-type disconnect switch is monitored in real time by a current sensor, and the data is collected by the data acquisition unit in the communication module. The data is then uploaded to the remote monitoring station via a wireless communication unit, allowing staff to view the current data in real time. When the current is abnormally high, a signal is sent to the warning light and speaker to activate the alarm mechanism. At the same time, an alarm is sent to the monitoring station via the communication module, allowing staff to see the emergency situation in time. It supports the simultaneous monitoring of multiple fuse-type disconnect switch devices. The humidity and temperature data of the humidity and temperature detectors are monitored and collected by the data acquisition unit in the communication module, allowing staff to view them in real time. The control unit in the communication module is connected to the fan. When staff feel that the data is abnormal or correct, they can manually adjust the fan's operating status through the control unit, manually switching the power supply between energy saving, normal operation, and high-efficiency operation to further save energy. The monitoring mechanism allows staff to monitor and view multiple devices simultaneously, supporting manual adjustments and further saving energy. Attached Figure Description

[0016] The following is in conjunction with the appendix Figure 1 - Appendix Figure 7This application will be described in further detail below.

[0017] Example 1: A fuse-type disconnect switch, referring to... Figures 1-6 It includes a heat dissipation mechanism 1, a temperature control mechanism 2 is installed inside the heat dissipation mechanism 1, a monitoring mechanism 3 is installed on the top of the temperature control mechanism 2, the monitoring mechanism 3 is fixedly connected to the outside of the heat dissipation mechanism 1, and the temperature control mechanism 2 is installed inside the heat dissipation mechanism 1. The heat dissipation mechanism 1 includes a fuse-type disconnect switch body 101. A protective shell 105 is provided at the bottom of the fuse-type disconnect switch body 101. A power supply 110 is fixedly connected inside the protective shell 105. A fan 111 is provided on the right side of the power supply 110. The bottom of the fan 111 is fixedly connected to the bottom of the inner wall of the protective shell 105. An air inlet pipe 112 is fixedly connected to the inlet of the fan 111. The left side of the air inlet pipe 112 is attached to the power supply 110. An exhaust plate 114 is fixedly connected inside the protective shell 105. A baffle plate 113 is attached to the top of the exhaust plate 114. The front of the baffle plate 113 is fixedly connected to the inside of the protective shell 105. The output port of the fan 111 is adapted to the exhaust plate 114.

[0018] Specifically, the fuse-type disconnect switch body 101 is the main body, the protective shell 105 serves as the supporting foundation and for integration, power is supplied to other structures via power supply 110, and air is drawn in through air inlet duct 112 by fan 111 and blown out. The inlet of air inlet duct 112 is directly opposite the bottom of fuse-type disconnect switch body 101. The bottom of fuse-type disconnect switch body 101 itself has vent holes, through which the fan 111 draws in the gas inside fuse-type disconnect switch body 101 along with the outside air. The system draws in and blows out cold air, mixing it with the fuse-type disconnect switch body 101. This mixture is then blown into the space created between the baffle plate 113, the exhaust plate 114, and the fan 111. The air is then blown out from the exhaust port of the exhaust plate 114. After the air dissipates heat inside the protective shell 105, it is released from the top due to air pressure. The air, which has been mixed with and cooled from the outside, is then blown back into the fuse-type disconnect switch body 101. This causes the original gas inside the fuse-type disconnect switch body 101 to be squeezed out and drawn in by the fan 111, thus achieving a cooling cycle.

[0019] A positioning rod 103 is fixedly connected to the bottom of the fuse-type disconnect switch body 101, and a fixing ring 104 is fixedly connected to the top of the protective shell 105. The inside of the fixing ring 104 is adapted to the positioning rod 103. A round hole is opened inside the protective shell 105, and the round hole is inserted into the positioning rod 103.

[0020] Specifically, the fuse-type disconnect switch body 101 is mounted on the protective housing 105 by the positioning rod 103, and the positioning rod 103 serves as a support. The fixing ring 104 is fixed inside the protective housing 105 to facilitate the insertion of the positioning rod 103 and to increase the contact area between the positioning rod 103 and the positioning rod 103, thereby enhancing stability. The bottom of the positioning rod 103 is convex and has the same shape as the round hole inside the protective housing 105, so that the positioning rod 103 can fit perfectly after being inserted into the round hole inside the protective housing 105 and will not easily fall off, thus strengthening the fixing ability.

[0021] The fuse-type disconnect switch body 101 has a heat-conducting copper sheet 102 fixedly connected inside. There are two heat-conducting copper sheets 102, and both heat-conducting copper sheets 102 are adapted to the same fan 111.

[0022] Specifically, the heat-conducting copper sheet 102 conducts and dissipates the temperature inside the fuse-type disconnect switch body 101, and the fan 111 dissipates heat from the heat-conducting copper sheet 102. When the fan 111 is not turned on, it can share some of the high temperature inside the fuse-type disconnect switch body 101.

[0023] The top of the protective shell 105 is provided with an outer frame 106, and a dustproof net 107 is fixedly connected inside the outer frame 106. The dustproof net 107 is adapted to the protective shell 105.

[0024] Specifically, the dustproof mesh 107 inside the outer frame 106 protects the structure inside the protective shell 105, preventing debris from falling in or dust from being blown or drawn into the protective shell 105 by the fan 111, thus weakening the heat dissipation effect.

[0025] Two fixing plates 108 are fixedly connected to the outer side of the outer frame 106. Fixing devices 109 are threadedly connected to the inside of the fixing plates 108. The fixing devices 109 are threadedly connected to the inside of the protective shell 105.

[0026] Specifically, the outer frame 106 can be fixed to the protective shell 105 by the fixing plate 108 and the fixing device 109. When cleaning or maintenance of the internal structure of the protective shell 105 is required, the outer frame 106 can be removed by removing the fixing device 109 for easy maintenance.

[0027] The temperature control mechanism 2 includes a temperature detector 201, which is installed on the outside of the protective housing 105 and inside the protective housing 105. A humidity detector 202 is installed inside the protective housing 105. A mounting plate 203 is fixedly connected inside the protective housing 105. A warning light 204 is fixedly connected to the back of the mounting plate 203. A speaker 205 is fixedly connected to the front of the mounting plate 203. The warning light 204 extends through the interior of the protective housing 105 and extends to the back of the protective housing 105. Both the warning light 204 and the speaker 205 are electrically connected to the fuse-type disconnect switch body 101. Both the warning light 204 and the speaker 205 are electrically connected to the humidity detector 202. Both the warning light 204 and the speaker 205 are electrically connected to the temperature detector 201.

[0028] Specifically, the temperature detector 201 and humidity detector 202 can detect the gas inside the protective housing 105. The gas inside the protective housing 105 comes from inside the fuse-type disconnect switch body 101. When the temperature is too high or the humidity is too high, a signal is sent to the warning light 204 and the speaker 205, causing the warning light 204 to light up and the speaker 205 to warn the surrounding area, reminding the staff to check the equipment.

[0029] Temperature detector 201 is electrically connected to fan 111, and humidity detector 202 is electrically connected to fan 111.

[0030] Specifically, when the temperature detector 201 detects a high temperature, or when the humidity detector 202 detects a high humidity, a signal is sent to the fan 111 to make it run at a higher efficiency. When the temperature or humidity is normal, the fan 111 is made to run at a low energy consumption efficiency.

[0031] The implementation principle of this application embodiment is as follows: the fuse-type disconnect switch body 101 is the main body, the protective shell 105 is the supporting foundation and integration, the power supply 110 provides power to other structures, and the fan 111 draws in air from the air inlet duct 112 and blows the air out. The inlet of the air inlet duct 112 is directly opposite the bottom of the fuse-type disconnect switch body 101. The bottom of the fuse-type disconnect switch body 101 itself has a vent hole. The fan 111 draws in and blows out the gas inside the fuse-type disconnect switch body 101 and the outside air through the vent hole, thus mixing the outside cold air with the outside air. After mixing, the airflow is blown into the space between the baffle plate 113, the exhaust plate 114, and the fan 111, and then blown out from the exhaust port of the exhaust plate 114. After dissipating heat inside the protective shell 105, the airflow is released from the top due to air pressure, and the airflow mixed and cooled by the outside is blown back into the fuse-type disconnect switch body 101. This causes the original gas inside the fuse-type disconnect switch body 101 to be squeezed out and drawn in by the fan 111, achieving a cooling cycle. The fuse-type disconnect switch body 101 is installed on the protective shell 105 by the positioning rod 103, which serves as a support. The fixing ring 104 is used for fixing. Inside the protective shell 105, the positioning rod 103 is inserted to facilitate its insertion and increase the contact area with the positioning rod 103, thus enhancing stability. The bottom of the positioning rod 103 is convex and matches the shape of the circular hole inside the protective shell 105, ensuring a perfect fit after insertion and preventing easy detachment, thus strengthening the fixing ability. The heat-conducting copper sheet 102 conducts and dissipates the temperature inside the fuse-type disconnect switch body 101, and the fan 111 dissipates heat from the heat-conducting copper sheet 102. When the fan 111 is not turned on, it can share some of the heat of the fuse-type disconnect switch body 101. The high temperature inside the casing 105 is protected by the dustproof net 107 inside the outer frame 106, which prevents debris from falling in or dust from being blown or sucked into the casing 105 by the fan 111, thus weakening the heat dissipation effect. The outer frame 106 can be fixed to the casing 105 by the fixing plate 108 and the fixing device 109. When cleaning or maintenance of the internal structure of the casing 105 is required, the outer frame 106 can be removed by removing the fixing device 109 for easy maintenance. The heat dissipation mechanism 1 can efficiently dissipate heat from the fuse-type disconnect switch body 101 in a timely manner and is easy to disassemble and maintain.The temperature detector 201 and humidity detector 202 can detect the gas inside the protective housing 105, which originates from the inside of the fuse-type disconnect switch body 101. When the temperature is too high or the humidity is too high, a signal is sent to the warning light 204 and the speaker 205, causing the warning light 204 to light up and the speaker 205 to warn nearby personnel to check the equipment. When the temperature detector 201 detects a high temperature or the humidity detector 202 detects a high humidity, a signal is sent to the fan 111 to make it run at a higher efficiency. When the temperature or humidity is normal, the fan 111 runs at a low energy consumption efficiency. The temperature control mechanism 2 can automatically adjust the operating intensity of the fan 111 according to the current state, achieving automated heat dissipation and further enhancing heat dissipation capacity while saving energy costs.

[0032] Example 2: A fuse-type disconnect switch, referring to... Figure 7 The monitoring mechanism 3 includes a current sensor 301, which is fixedly connected to the outside of the fuse-type disconnect switch body 101 and electrically connected to the fuse-type disconnect switch body 101. A communication module 302 is fixedly connected to the outside of the fuse-type disconnect switch body 101. The communication module 302 includes a wireless communication unit, a control unit, and a data acquisition unit. The communication module 302 is electrically connected to the current sensor 301.

[0033] Specifically, the current inside the fuse-type disconnector switch body 101 is monitored in real time by the current sensor 301, and the data is collected by the data acquisition unit in the communication module 302. The data is then uploaded to the remote monitoring station via the wireless communication unit, allowing staff to view the current data in real time. When the current is abnormally high, a signal is sent to the warning light 204 and the speaker 205 to activate their alarm mechanism. At the same time, an alarm is sent to the monitoring station via the communication module 302, allowing staff to view the crisis situation in a timely manner and supporting the simultaneous monitoring of multiple fuse-type disconnector switches.

[0034] The communication module 302 is electrically connected to the humidity detector 202, the temperature detector 201, and the fan 111.

[0035] Specifically, the data acquisition unit in the communication module 302 monitors and collects humidity and temperature data from the humidity detector 202 and temperature detector 201, allowing staff to view the data in real time. At the same time, the control unit in the communication module 302 is connected to the fan 111. When staff feel that the data is abnormal or that the data is correct, they can manually adjust the working status of the fan 111 through the control unit, manually switching the power supply between energy saving, normal operation and high-efficiency operation, further saving energy.

[0036] The implementation principle of this application embodiment is as follows: the current in the fuse-type disconnector switch body 101 is monitored in real time by the current sensor 301, and the data is collected by the data acquisition unit in the communication module 302. The data is then uploaded to the remote monitoring station via the wireless communication unit, allowing staff to view the current data in real time. When the current is abnormally high, a signal is sent to the warning light 204 and the speaker 205 to activate their alarm mechanism. At the same time, an alarm is sent to the monitoring station via the communication module 302, enabling staff to view the emergency situation in a timely manner and supporting the simultaneous monitoring of multiple fuse-type disconnectors. The system monitors and collects humidity and temperature data from humidity detector 202 and temperature detector 201 through the data acquisition unit within the communication module 302, allowing staff to view the data in real time. Simultaneously, the control unit within the communication module 302 is connected to the fan 111. When staff perceive abnormal or incorrect data, they can manually adjust the fan 111's operating status via the control unit, switching between energy-saving, normal operation, and high-efficiency operation to further conserve energy. The monitoring mechanism 3 enables staff to monitor multiple devices simultaneously, supporting manual adjustments and further energy savings.
