[0033] The following describes preferred embodiments of the present invention in greater detail. Although preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0034] The utility model provides a drawer-type ignition explosion-proof cabinet, comprising:

[0035] The explosion-proof cabinet body includes at least one layer of equipment installation grid;

[0036] The drawer-type bracket is connected to one side of the equipment installation grid through the track assembly;

[0037] The power input box and high-voltage power output box are respectively arranged on the other side of the equipment installation grid. The power input box is provided with an input power explosion-proof connector, and the high-voltage power output box is provided with a high-voltage ceramic terminal.

[0038] Multiple door-opening power disconnect switches are arranged in the equipment installation grid, the door-opening power disconnect switches are connected to door-opening protection circuit breakers, and the door-opening power disconnect switches are respectively arranged corresponding to the drawer-type bracket, the box door of the power input box, and the box door of the high-voltage power output box;

[0039] The high-energy igniter is installed on a drawer-type bracket and is connected to the high-voltage ceramic terminal;

[0040] The switch is arranged on the outside of the drawer-type bracket, and the switch is connected to the high-energy igniter control;

[0041] The high-voltage indicator light and the power indicator light are arranged on the outside of the drawer-type bracket. The power indicator light is connected to the door-opening power switch signal, and the high-voltage indicator light is connected to the high-energy igniter and the high-voltage current and voltage monitoring module signal.

[0042] Specifically, the drawer-type ignition explosion-proof cabinet mainly includes two parts: an explosion-proof cabinet body and a drawer-type bracket. A drawer-type bracket is movably arranged in each layer of the equipment installation grid, and the drawer-type bracket is pulled out on one side of the equipment installation grid. A power input box and a high-voltage power output box are also arranged on the other side of the corresponding equipment installation grid. These two boxes are also provided with openable and closable box doors. A high-energy igniter is arranged inside the drawer-type bracket, an input power explosion-proof connector is arranged in the power input box, and a high-voltage ceramic terminal is arranged in the high-voltage power output box. When the drawer-type bracket and the box door are both closed, the door is opened and the power switch is disconnected to receive a signal for power-on. The input power explosion-proof connector, the high-energy igniter and the high-voltage ceramic terminal are connected in sequence, and the power indicator light on the outside of the drawer-type bracket will be lit. As long as the switch is started, the voltage of the high-energy igniter can be output from the high-voltage ceramic terminal to achieve ignition. At the same time, the high-voltage indicator light will also be lit, indicating that the ignition high-voltage output is normal. The drawer-type explosion-proof ignition cabinet's design is simple and convenient to operate, ensuring a safe and reliable ignition system. Its simple structure also facilitates future inspection and maintenance. When a circuit problem occurs in the drawer-type explosion-proof ignition cabinet, the door-opening protection circuit breaker trips. The power switch, disconnected by the door, cannot detect the open or closed status of the drawer-type bracket and the cabinet door, preventing communication between the input power explosion-proof connector, the high-energy igniter, and the high-voltage ceramic terminal.

[0043] Optionally, multiple high-voltage relays are provided on the inner side of the drawer-type bracket, and corresponding high-voltage relay switches are provided on the outer side of the drawer-type bracket. A high-energy igniter is connected to multiple high-voltage relays, and the high-voltage relays are connected to high-voltage ceramic terminals.

[0044] Specifically, in addition to setting up a high-energy igniter on the drawer-type bracket, high-voltage relays can also be used to replace some high-energy igniters, thereby reducing the number of high-energy igniters and effectively controlling the economic cost of the ignition explosion-proof cabinet; a high-energy igniter is connected to multiple high-voltage relays, and a high-voltage relay switch is set between the two. When a certain high-voltage ceramic terminal needs to output voltage, the corresponding high-voltage relay switch is connected. In this way, when the power indicator light and the high-voltage indicator light are on, the voltage of the high-energy igniter can be transmitted to the corresponding high-voltage ceramic terminal through the high-voltage relay.

[0045] Optionally, a distribution switch contact is provided in the equipment installation grid, and a plurality of matching switch contacts are provided on the explosion-proof cabinet body. The matching switch contacts are connected one by one to the high-voltage ceramic terminals. A conversion distribution switch is provided on the outside of the drawer-type bracket corresponding to the distribution switch contact. When the drawer-type bracket is closed in the explosion-proof cabinet body, the conversion distribution switch connects the high-energy igniter with a matching switch contact. The conversion distribution switch can control the connection mode between the distribution switch contact and multiple matching switch contacts.

[0046] Specifically, distribution switch contacts and matching switch contacts can be used on the drawer-type bracket to replace part of the high-energy igniter. When the drawer-type bracket is closed, the distribution switch contacts can be controlled to connect with one of the matching switch contacts by switching the distribution switch. In this way, the high-energy igniter is connected to the corresponding high-voltage ceramic terminal. When the power indicator light and the high-voltage indicator light are on, the voltage of the high-energy igniter can be transmitted to the corresponding high-voltage ceramic terminal through the distribution switch contacts and a matching switch contact. If the output voltage of other high-voltage ceramic terminals needs to be changed, it can be achieved by adjusting the conversion distribution switch. The operation is simple and convenient, and future maintenance is even easier.

[0047] Optionally, a distribution switch bracket is provided on the equipment installation grid, and when the drawer-type bracket is in a closed state, the distribution switch bracket connects the output end of the high-energy igniter with the input end of the distribution switch contact.

[0048] Specifically, a distribution switch bracket is installed in the equipment installation grid. When the drawer-type bracket is closed on the explosion-proof cabinet body, the distribution switch bracket pushes the output end of the high-energy igniter to connect with the distribution switch contact. In this way, when the power indicator light and the high-voltage indicator light are on, the voltage of the high-energy igniter can be transmitted to the high-voltage ceramic terminal connected to the matching switch contact; when the drawer-type bracket is pulled out from the explosion-proof cabinet body, not only can the door be opened to disconnect the power switch to disconnect the input voltage of the drawer-type ignition explosion-proof cabinet, but the high-energy igniter and the distribution switch contacts are also disconnected, ensuring the safety of the drawer-type ignition explosion-proof cabinet during use.

[0049] Optionally, the track assembly includes a sliding track and a mounting track that slide with each other, the sliding track is connected to the drawer-type bracket, and the mounting track is connected to the explosion-proof cabinet body.

[0050] Specifically, sliding rails are installed on both sides of the drawer-type bracket, and mounting rails are installed in each layer of the equipment installation grid. In this way, through the coordinated movement of the sliding rails and the mounting rails, the drawer-type bracket can be pulled out and moved in the equipment installation grid, and a door-opening power switch is also provided on the upper side of each layer of the equipment installation grid. When the drawer-type bracket is closed, the ignition explosion-proof cabinet can be powered on.

[0051] Optionally, the switch includes a remote transfer switch and a local ignition button.

[0052] Specifically, the drawer-type ignition explosion-proof cabinet can use a remote conversion switch or a local ignition button to start the high-energy igniter, thereby expanding the scope of use of the ignition explosion-proof cabinet. The two switch buttons can also be set at the same time. When one switch button fails, the other switch button can be immediately switched to start the ignition explosion-proof cabinet, thereby ensuring the operational stability of the ignition explosion-proof cabinet.

[0053] Optionally, the input power explosion-proof connector is used to connect to a 220V power supply, and the input power explosion-proof connector is connected in turn to one end of the automatic and manual AC / DC converter, the transformer, and the control components, and the other end of the transformer and the control components is connected to the high-voltage ceramic terminal through a thyristor thyristor or a ceramic discharge tube.

[0054] Specifically, the input end of the drawer-type explosion-proof ignition cabinet is an input power explosion-proof connector that can be connected to a 220V power supply. When the door is opened and the power switch is disconnected, and both the open and closed states are detected, the AC power enters the automatic and manual AC / DC converters and transformers and control components in sequence and is transmitted toward the high-voltage ceramic terminals. During this process, discharge can be performed through thyristors, thyristors, or ceramic discharge tubes to achieve the connection between the high-voltage power supply and the high-voltage ceramic terminals. The equipment is connected through the high-voltage cables on the terminals to achieve the ignition function. The above connection structure is not the key content to be protected in this application.

[0055] Optionally, the explosion-proof cabinet body is also provided with an AC input power explosion-proof connector for connecting to a 24V power supply, and the AC input power explosion-proof connector is connected to one end of the automatic and manual AC-DC converter, transformer and control components in turn, and the automatic and manual AC-DC converter, transformer and control components are also provided with a DC to AC inverter.

[0056] Specifically, when the AC power fails, a 24V power supply can be connected to the AC input power explosion-proof connector. After passing through the automatic manual AC / DC converter, automatic switching is achieved. The DC power supply is then connected to the transformer and control components through the DC / AC inverter, and can also power the high-voltage terminal. In this connection structure, the ability to convert current through the DC / AC inverter is the key innovation.

[0057] Optionally, the power indicator light includes a DC power indicator light and an AC power indicator light.

[0058] Specifically, when the drawer-type ignition explosion-proof cabinet is powered on, the DC power indicator light or the AC power indicator light is on, indicating the type of power supply used by the drawer-type ignition explosion-proof cabinet.
