Abstract
Description
Technical Field
[0001] The invention relates to the field of electrical simulation experiments, and in particular to an adjustable electrical fault simulation device. Background Art
[0002] In electrical system fault simulation experiments, traditional fault simulation devices usually have a single function, mainly focusing on simulating electrical faults, but are obviously insufficient in dealing with dangerous situations that may be caused during the experiment. In particular, in the two key links of cutting off the circuit and extinguishing the fire, the design and function of traditional devices have the following limitations: 1. Traditional devices rely on manual operation or simple mechanical switches to cut off the circuit, and cannot achieve fast and accurate automatic cutting. When abnormal conditions such as excessive current, short circuit or high temperature occur during the experiment, manual operation often reacts slowly and it is difficult to cut off the circuit in time, which may cause the fault to expand further and even cause fire or other safety accidents; 2. Traditional devices usually lack automatic fire extinguishing functions, or are only equipped with simple fire extinguishing equipment (such as manual fire extinguishers). When an open fire is caused by an electrical fault during the experiment, the operator needs to manually activate the fire extinguishing equipment, which not only increases the complexity of the operation, but may also lead to untimely fire extinguishing, causing the fire to spread and cause greater losses.

DETAILED DESCRIPTION
[0024] The present invention is further described below in conjunction with specific embodiments. It should also be noted that, unless otherwise clearly specified and limited, terms such as: setting, installing, connecting, and connecting should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example 1
[0025] An adjustable electrical fault simulation device, such as Figure 1-Figure 9 As shown, it includes a simulation box 1, a box door 2 is rotatably connected to the front side of the simulation box 1, an observation window 3 is arranged on the box door 2, a main control terminal 4 is arranged on the right side of the simulation box 1, simulation power supplies 5 are arranged on the left and right sides of the simulation box 1, electric push rods 6 are installed inside the simulation power supplies 5, clips 7 are connected to the telescopic ends of the electric push rods 6, and a cutting mechanism 8 for quickly cutting off the connecting wires is arranged inside the simulation power supplies 5. A fire extinguishing mechanism 9 is arranged on the top of the simulation box 1, and the fire extinguishing mechanism 9 is used to quickly extinguish open flames.
[0026] It should be noted that the simulated power supply 5 inside the device is used to simulate the power supply in the electrical system. By adjusting the output parameters of the simulated power supply 5 (such as voltage, current, etc.), different electrical fault conditions can be simulated, such as short circuit, overload, voltage fluctuation, etc., and by controlling the extension and retraction of the electric push rod 6, the loose or disconnected connection of the wires can be simulated, thereby simulating poor contact or broken wire failures. When a dangerous situation occurs during the simulation (such as excessive current or high temperature), the cutting mechanism 8 will act quickly to cut off the connecting wires to prevent the fault from further expanding or causing serious consequences such as fire. If an open flame occurs, the fire extinguishing mechanism 9 can automatically start when a flame or high temperature is detected to ensure the safety of the device and the operator.
[0027] The cutting mechanism 8 includes a first mounting plate 81. The first mounting plate 81 is arranged on the top of the simulated power supply 5. The inner side of the first mounting plate 81 is connected to a sleeve 82. A strong magnetic block 83 is adsorbedly connected inside the sleeve 82. The strong magnetic block 83 is connected to the top of the sleeve 82. The strong magnetic block 83 is electrically connected to the simulated power supply 5. A spring 85 is connected to the bottom of the strong magnetic block 83. A connecting rod 84 is connected to the bottom of the spring 85. A cutter head 86 is connected to the bottom of the connecting rod 84. The cutter head 86 is used to cut the wires. A base 88 is connected to the bottom of the sleeve 82. The base 88 is connected to the bottom of the simulation box 1. The base 88 is used to guide the wires.
[0028] It should be noted that, in normal operation, the strong magnetic block 83 is magnetically adsorbed on the top of the sleeve 82 and electrically connected to the simulated power supply 5 to maintain the power-on state. At this time, the spring 85 is in a compressed state, the connecting rod 84 and the cutter head 86 are located inside the sleeve 82, and the cutter head 86 maintains a certain distance from the wire. The wire is guided through the base 88 and is normally conducted. As the fault simulation experiment begins, when the simulated power supply 5 detects an abnormal situation (such as excessive current, short circuit or high temperature, etc.), the simulated power supply 5 will cut off the power supply to the strong magnetic block 83. Since the strong magnetic block 83 loses power support, its magnetism weakens or disappears, and it can no longer be adsorbed on the top of the sleeve 82. After the strong magnetic block 83 loses its magnetism, the compressed spring 85 quickly releases its elastic force and pushes the connecting rod 84 downward. The cutter head 86 at the bottom of the connecting rod 84 moves downward accordingly, quickly cutting off the wire guided through the base 88, thereby interrupting the circuit and preventing the fault from further expanding.
[0029] The fire extinguishing mechanism 9 includes a fire extinguisher 91, which is connected to the rear side of the simulation box 1, a second mounting plate 92 is connected to the rear side of the simulation box 1, a discharge pipe 93 is connected between the second mounting plate 92 and the simulation box 1, the discharge pipe 93 is connected to the fire extinguisher 91, a nozzle 94 is connected to the lower side of the front of the discharge pipe 93, and a fire source detector 95 for detecting open flames is connected to the lower side of the second mounting plate 92.
[0030] It should be noted that inside the simulation box 1, the fire source detector 95 monitors the temperature or flame signal in the environment in real time. When an open flame or high temperature is generated due to an electrical fault or other reasons during the simulation process, the fire source detector 95 can quickly detect the abnormal situation. Once the fire source detector 95 detects an open flame or high temperature, it will immediately send a trigger signal to the fire extinguishing mechanism 9 to start the release mechanism of the fire extinguisher 91. After the fire extinguisher 91 receives the trigger signal, the internal fire extinguishing agent (such as dry powder, gas or foam) is quickly transported to the inside of the simulation box 1 through the discharge pipe 93. The nozzle 94 on the lower front side of the discharge pipe 93 evenly sprays the fire extinguishing agent into the fire source area to ensure that the fire extinguishing agent can cover the open flame. After the fire extinguishing agent is sprayed through the nozzle 94, the combustion reaction of the flame is quickly suppressed, the temperature is reduced and oxygen is isolated, thereby achieving the effect of quickly extinguishing the open flame. This process can be completed in a very short time, effectively preventing the spread of fire. Example 2
[0031] On the basis of Example 1, it also includes a recycling mechanism 10, which includes a collection frame 101. A slide groove is opened at the bottom of the simulation box 1, and the collection frame 101 is slidably connected in the slide groove. The collection frame 101 is used to collect waste generated during the simulation experiment. A handle 102 is connected to the front side of the collection frame 101, and two left-right symmetrical limit blocks 103 are connected to the bottom of the simulation box 1. The limit blocks 103 are used to block the collection frame 101.
[0032] It should be noted that during the simulation experiment, the waste generated (such as cut wire fragments, fire extinguishing agent residues or other experimental waste) will naturally fall to the bottom of the simulation box 1. Since the aggregate frame 101 is located at the bottom of the simulation box 1 and is slidably connected by a slide groove, the waste will fall directly into the aggregate frame 101 to achieve centralized collection. When the experiment is over or the waste in the aggregate frame 101 reaches a certain amount, the operator can pull the aggregate frame 101 out of the slide groove through the handle 102. After cleaning the waste in the aggregate frame 101, the operator can push the aggregate frame 101 back into the slide groove at the bottom of the simulation box 1 until the limit block 103 fixes it in place.
[0033] It also includes a smoke treatment mechanism 11, which includes a purification box 111. The purification box 111 is connected to the left side of the simulation box 1, and an exhaust pipe 112 is connected between the top of the purification box 111 and the top of the simulation box 1. A filter plate 113 is provided at the right end of the exhaust pipe 112. A smoke detector 114 is connected to the top of the simulation box 1, and the smoke detector 114 is used to detect the smoke condition, thereby starting the purification box 111 for exhaust treatment.
[0034] It should be noted that during the simulation experiment, if smoke is generated due to electrical failure or other reasons, the smoke detector 114 connected to the top of the simulation box 1 will monitor the smoke concentration in the box in real time. When the smoke concentration exceeds the set threshold, the smoke detector 114 will immediately send a signal to trigger the smoke treatment mechanism 11 to start. After the smoke detector 114 is triggered, the purification box 111 starts to work. The purification box 111 is connected to the top of the simulation box 1 through the exhaust pipe 112 at the top. The right end of the exhaust pipe 112 is provided with a filter plate 113 for preliminary filtering of large particle pollutants. After the exhaust device (such as a fan) in the purification box 111 is started, the smoke in the simulation box 1 is sucked into the purification box 111 through the exhaust pipe 112.
[0035] The box door 2 further comprises a sealing mechanism 12 , which comprises a sealing ring 121 . The front side of the box door 2 is connected with the sealing ring 121 . A limiting member 122 is arranged on the sealing ring 121 . The limiting member 122 is used to assist an operator in quickly removing the sealing ring 121 .
[0036] It also includes an anti-slip cover 13, and the handle is provided with an anti-slip cover 13.
[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
