Description

A safety distribution box

technical field

The utility model relates to the field of distribution boxes, in particular to a safety distribution box.

Background technique

The distribution box is a general circuit distribution box for all users to use electricity.

Power distribution box is assembled in closed or semiclosed metal safe by electrical wiring requirement by switchgear, measuring instrument, protective device and auxiliary equipment or on screen width, forms low-voltage distribution equipment. During normal operation, the circuit can be connected or disconnected by means of a manual or automatic switch. Cut off the circuit or alarm with the help of protective electrical appliances in case of failure or abnormal operation. Various parameters in operation can be displayed by means of measuring instruments, and some electrical parameters can also be adjusted to prompt or send out signals for deviations from normal working conditions. Commonly used in various power generation, distribution and substations.

The purpose of the distribution box: to distribute electric energy reasonably, and to facilitate the opening and closing operation of the circuit. It has a high level of safety protection and can intuitively display the conduction state of the circuit. It is easy to manage, and it is convenient for maintenance when a circuit failure occurs.

At present, most distribution boxes ignore the live wiring part of the components behind the door panel. Due to the long time or the connection is not firm, the conductive part is exposed, which is easy to cause a short circuit and fire, or the operator accidentally touches it. cause safety incidents. The design of the distribution box also needs continuous improvement and improvement.

Contents of the invention

Aiming at the above-mentioned shortcomings of the current distribution box, the utility model provides a safety distribution box that isolates all live parts in the distribution box to avoid the danger of electric shock.

The technical scheme adopted by the utility model to achieve its technical purpose is: a safety distribution box, including a box body, a mounting plate for installing components supported by a bottom plate support bar in the box body, and a A box door hingedly installed on the box door is provided with a group of indicator lights, buttons, and switch knobs; an insulating isolation plate is also provided at the installation place of the indicator lights, buttons, and switch knobs described on the back of the box door.

In the utility model, an insulating isolation plate is used on the back of the box door to isolate the indicator light from the button and the installation place of the switch knob, so as to ensure that the conductive part will not be exposed due to too long time or the connection is not firm, which may easily cause short circuit and fire , or safety accidents caused by careless touches by operators.

Further, in the above-mentioned safety distribution box: the insulating and separating board is a plexiglass board, which is installed by four brackets welded behind the box door.

Further, in the above-mentioned safety distribution box: the bracket is in the shape of a "Z", and the insulating isolation board is fixed on the bracket by screws.

Further, in the above-mentioned safety distribution box: the inner sealing plate supported by the inner sealing plate support bar is also arranged in the said box.

Further, in the above-mentioned safety distribution box: a door lock is also provided on the box door, and the door lock includes lock catches arranged on the upper and lower sides of the box door in linkage.

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.

detailed description

Embodiment 1 As shown in Figure 1, this embodiment is a safety distribution box for fan power distribution. The fan normally uses the common power supply to work, and if the common power supply is abnormal, it is converted to the backup power supply to work. Including a box body 1, a mounting plate 2 for installing components supported by a bottom plate support bar 3 in the box body, an inner sealing plate 4 supported by an inner sealing plate support bar 5 is arranged in the box body 1, and an inner sealing plate 4 supported by an inner sealing plate support bar 5 is provided in the box body The front of the box 1 is provided with a box door 6 hingedly installed with the box body 1. Several outlet hole rubber rings 7 are arranged on the top of the box body 1. The box door can rotate along the hinge axis to realize the switch of the box door. A group of indicator lamps 11 and buttons 12, switch knob 13 and door lock 8 are arranged on it. The indicator lights are some LED lights, including common power indicator, common closing indicator, standby power indicator, standby closing indicator, fan running indicator, fan failure indicator and fan stop indicator, etc. LED for power status.

In the safety distribution box of this embodiment, there is an intelligent detection circuit board, which judges the power supply by detecting the power supply status of the common power supply and the standby power supply. If the common power supply has a fault, that is, the voltage does not meet the requirements, such as When the voltage is unstable, the frequency is unstable or there is a power failure, the status is indicated by the indicator light of the common power supply. If there is a fault, the indicator light of the common power supply is red, and if it is normal, the indicator light of the normal power supply is green. If there is a fault, it will automatically switch to the backup power supply, and at the same time make the backup power indicator light and the backup closing indicator light on, and turn off the common closing indicator light.

The circuit board also has a detection circuit for detecting the working state of the fan. If the fan is working normally, the fan running indicator light is on. If the fan is not working normally, the fan fault indicator is on.

The buttons 12 include two buttons, a fan start button and a fan stop button, and the switch knob 13 has three states: manual, stop and automatic.

The door lock 8 includes lock catches which are interlockedly arranged on the upper and lower sides of the box door.

In order to ensure safety in this embodiment, an insulating isolation plate 9 is also provided at the installation place of the indicator light 11, the button 12, and the switch knob 13 described on the back of the box door 6, so that the wiring of the indicator light 11, the button 12, and the switch knob 13 are no longer exposed. ,ensure safety. In the present embodiment, the insulating spacer 9 is a plexiglass plate, and the plexiglass plate adopts four brackets 10 welded behind the chamber door 6 to install. The support 10 is a "Z" shape, and the machine glass plate is fixed on the support 10 by screws.

In this embodiment, the height of the bracket is determined according to the depth behind the door of the components such as the indicator light 11, button 12, and switch knob 13. It only needs to be a little deeper than the depth behind the door of the components. Install the plexiglass panels.
