Description

Anti-misoperation locking device for intelligent high-voltage switchgear

technical field

The utility model relates to an anti-misoperation locking device, in particular to an anti-misoperation locking device for an intelligent high-voltage switch cabinet.

Background technique

The switchgear is a kind of live equipment. The staff may operate some components in the switchgear when the main control switch is charged, which is prone to operating accidents. At present, the contact live display and mechanical lock phase are mostly used in the market. Cooperating, this method is inconvenient and easy to damage, difficult to troubleshoot and repair, and cannot guarantee normal operation and use.

Utility model content

The technical problem to be solved by the utility model is to provide an intelligent anti-misoperation locking device for high-voltage switchgear, which can realize accurate judgment, display electrification status, and can intelligently lock.

The utility model solves the above-mentioned technical problems through the following technical solutions: an intelligent anti-misoperation locking device for high-voltage switchgear, which is characterized in that it includes a reset lever, a key hole, a three-phase display, an operation hole door, a special Key, control display unit, sensor communication line, there is a reset lever in the upper left corner of the control display unit, the sensor communication line is located in the upper right corner of the control display unit, the key hole is located in the middle of the control display unit, the three-phase display is located below the key hole, and the operation hole door is located in the At the bottom of the control display assembly, the special key is inserted into the key hole when working.

Preferably, the special key is provided with a charging display indicator light and an unlocking electric test button.

The positive and progressive effect of the utility model lies in that the utility model can realize accurate judgment, display electrification situation, and can lock intelligently.

Detailed ways

The preferred embodiments of the utility model are given below in conjunction with the accompanying drawings to describe the technical solution of the utility model in detail.

As shown in Figures 1 and 2, the utility model intelligent high-voltage switchgear anti-misoperation locking device is composed of a special key 5 and a control display assembly 6, and the control display assembly 6 includes a reset lever 1, a key hole 2, and a three-phase display 3 , the operation hole door 4, the sensor communication line 7, the upper left corner of the control display assembly 6 is provided with a reset lever 1, the sensor communication line 7 is located at the upper right corner of the control display assembly 6, the keyhole 2 is located in the middle of the control display assembly 6, and the three-phase display 3 is located at the Below the keyhole 2, the operating hole door 4 is positioned at the bottom of the control display assembly 6, and the special key 5 is inserted into the keyhole 2 during work. The special key 5 is provided with a charged display indicator light 51 and an unlocking electric test button 52 .

As shown in Figure 3, when operating, connect the sensor communication line 7 to the sensor in the switch cabinet, insert the special key 5 in sequence, and press the unlock button 52 for electric testing. Then the operating hole door 4 is opened, and the upper reset lever 1 pops up. After the operation is over, the operating hole door 4 is closed and the upper reset lever 1 is pressed to complete the unlocking process. Wherein, the special key 5 cannot be extracted when the reset lever 1 is not reset. The interior of the device adopts an intelligent logic analysis circuit. When there is high voltage in the switch cabinet, the charging display indicator 51 of the device will be lit, and the charging situation can be easily seen by the naked eye. At this time, the special key 5 worn at random can not be unlocked in time, and there is an alarm prompt. Unlock the lock smoothly for maintenance operations. This function is operated when there is no electricity in the cabinet. The voltage and instructions for unlocking are completely dependent on the standard key.

As shown in Figure 4, the control unit receives the electrification information from the sensor in the cabinet, the electrification display unit receives the transmitted high-voltage electrification status, and gives an alarm whether it is electrified or lack of phase, and the intelligent logic analysis circuit inside the control unit performs a blocking logic judgment , and then give the corresponding command to the locking circuit operation hole door.

The utility model integrates several major functions such as intelligent unlocking, misoperation prevention, live display, environmental protection and energy saving. The key power of the utility model is very strong, the stroke is in place, there is almost no wear and tear in use, and the service life is more than 500,000 times. In addition to replacing the battery, no other maintenance is required, and the data line can also be used for charging, and the keys of each device are universal, which can be called The above is a green, environmentally friendly and efficient replacement product for the power sector. The utility model adopts an intelligent logic analysis circuit inside, which can accurately judge and display whether the high-voltage switchgear is electrified and lacks a phase state, and is easy to use, maintain and repair, and is not easy to be damaged.

The specific embodiments described above have further described the technical problems, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above descriptions are only specific embodiments of the utility model and are not intended To limit the utility model, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model shall be included in the protection scope of the utility model. the
