In the utility model, 2 of the incoming line cabinet switches of 2 buses and the bus-bar cabinet switches between two buses of the two-way power supply system can only be switched on at any time, so that the situation of error opening and closing of load switches is prevented.
Description
Technical Field
The utility model relates to the field of medium-high voltage equipment, in particular to an interlocking structure of a double-inlet-wire cabinet and a bus-bar cabinet.
Background
In three switches, namely an incoming line cabinet switch of two buses and a bus-bar cabinet switch between two buses of the two-way power supply system, only two switches can be closed simultaneously. The ring closing is not allowed, and the error locking prevention can be additionally arranged at the possible ring closing point, so that the error opening and closing load switch can be prevented.
Therefore, an interlocking method is needed to be designed in a targeted way, and the situation that the load switch is switched on or off by mistake is prevented.
Disclosure of utility model
The utility model aims to: aiming at the defects and shortcomings of the prior art, the utility model provides an interlocking structure of a double-incoming-line cabinet and a bus-bar cabinet, wherein 2 incoming-line cabinet switches of 2 buses of a double-circuit power supply system and 3 bus-bar cabinet switches between two buses can only be switched on at any time, so that the situation of false-opening and false-closing of load switches is prevented.
The technical scheme is as follows: the utility model relates to an interlocking structure of a double-inlet wire cabinet and a bus-bar cabinet, which is characterized in that: key locks are respectively arranged at 3 load switches of the inlet wire cabinet switches of 2 buses of the double-circuit power supply system and the bus-bar cabinet switches between two buses, and 2 closing keys are shared by the 3 key locks.
Wherein 2 of the 3 key locks are closed and 1 is open.
The cylindrical head lock piece of the key lock is positioned at the side part of the nylon baffle plate of the mechanism.
The mechanism nylon baffle is positioned at a load switch operation hole of the incoming line cabinet or the bus-bar cabinet.
Wherein, the cylinder head locking plate is in a vertical state or a horizontal state.
The beneficial effects are that: compared with the prior art, the utility model has the following remarkable advantages: in the utility model, 2 of the incoming line cabinet switches of 2 buses and the bus-bar cabinet switches between two buses of the two-way power supply system can only be switched on at any time, so that the situation of error opening and closing of load switches is prevented. The practicability and the safety are improved.

FIG. 3 is a schematic diagram of a locked state of the key lock of the present utility model;
In the figure, 1 is a mechanism panel; 2 is a key lock; 3 is a lock mounting plate; 4 is a cylindrical head locking plate; and 5 is a mechanical nylon baffle.
Detailed Description
The technical scheme of the utility model is further described below with reference to the accompanying drawings and the specific embodiments.
According to the interlocking structure of the double-incoming-line cabinet and the bus-bar cabinet, key locks 2 are respectively installed at 3 load switches of the incoming-line cabinet switches of 2 buses of a double-circuit power supply system and the bus-bar cabinet switches between two buses, and 2 closing keys are shared by 3 key locks 2. 2 of the 3 key locks 2 are closed, and 1 is open. The key lock 2 is mounted on a lock mounting plate 3 of the mechanism panel 1 of the line incoming cabinet or the bus-bar cabinet. The cylinder head lock piece 4 of the key lock 2 is located at the side of the mechanism nylon damper 5. The mechanism nylon baffle 5 is positioned at the load switch operation hole of the incoming line cabinet or the bus-bar cabinet. The cylinder head locking plate 4 is in a vertical state or a horizontal state.
In the total 3 switches of the inlet wire cabinet switch of 2 buses of the double-circuit power supply system and the bus-bar cabinet switch between two buses, only 2 of the two switches can be switched on at any time. The following two cases are classified:
1. In normal operation, the master batch cabinet switch is normally in an off state. The double incoming line cabinet is switched on, and two sides are respectively powered.
2. In both ends of the female cabinet that allies oneself with, in case one side takes place to have a power failure, female cabinet switch is through closing a floodgate, is supplied power by the power of opposite side, has reduced the power failure time and has realized uninterrupted power supply, is that the system has higher power supply reliability.
The 3 key locks 2 are respectively fixed on the two incoming line cabinets and the mother cabinet mechanism panel 1 through the lock mounting plates 3, and are arranged at the left side of the load switch operation hole. Through using 3 key locks the only 2 keys, guarantee under any condition, two inlet wire cabinets and three cubicles of female cabinet that allies oneself with only 2 wherein can be closed simultaneously.
When the key lock is unlocked by the key, the cylindrical head lock plate is in a vertical state (figure 2), and the load switch unlocked by the key lock can be separated and combined. The two inlet wire cabinets and the bus-bar cabinet are provided with 3 key locks, only 2 key locks are arranged on the two inlet wire cabinets and the bus-bar cabinet, and any 2 load switches with the key locks can be separated and combined.
When the load switch is in the opening state, the key lock can lock and pull out the key, the cylindrical head locking plate is in a horizontal state (figure 3), and the mechanical nylon baffle plate is pulled to the right side, and at the moment, the load switch operation hole is blocked by the mechanical nylon baffle plate and can not be opened or closed. The load switches of keyless locks in the double-inlet cabinet and the bus-bar cabinet are locked and can not be separated and combined.
