Detailed Description
In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.
Referring to fig. 1 and 2, the present disclosure provides a solid insulated switchgear with an interlock device, particularly applicable to a 27.5kV switchgear, specifically including:
the isolation mechanism 100 is provided with an isolation operation brake platform for controlling the brake opening and the brake closing of the isolation mechanism 100;
the grounding mechanism 200 is provided with a grounding operation brake table for controlling the brake opening and the brake closing of the grounding mechanism 200;
the circuit breaker mechanism 300 is provided with a circuit breaker operating brake table for controlling the opening and closing of the circuit breaker mechanism 300;
the first interlocking mechanism is used for limiting the breaker operating brake platform when in the first working position, and is used for limiting the isolation operating brake platform and the grounding operating brake platform when in the second working position;
the second interlocking mechanism is in transmission connection with the isolation operation brake platform and is used for limiting the grounding operation brake platform when the isolation operation brake platform performs closing operation;
and the third interlocking mechanism is in transmission connection with the grounding operation brake platform and is used for limiting the isolation operation brake platform when the grounding operation brake platform performs closing operation.
In order to realize the five-prevention interlocking function, in the actual use process of the switch cabinet, the interlocking among the isolation mechanism 100, the grounding mechanism 200 and the breaker mechanism 300 needs to be ensured: when the isolation mechanism 100 and the grounding mechanism 200 are both in the opening state, the circuit breaker mechanism 300 is not allowed to be operated to close; when the isolation mechanism 100 is switched on, the grounding mechanism 200 cannot be switched on, and when the grounding mechanism 200 is switched on, the isolation mechanism 100 cannot be switched on; after either of the isolation mechanism 100 or the grounding mechanism 200 is closed, the circuit breaker mechanism 300 can be operated to close while the isolation mechanism 100 or the grounding mechanism 200 is not allowed to perform the opening operation.
In this embodiment, the first operating position of the first interlock mechanism is an initial operating position, and at this time, the isolation mechanism 100, the grounding mechanism 200, and the circuit breaker mechanism 300 are all in an open state, and in this state, the circuit breaker mechanism 300 is not allowed to be operated to close, so when the first interlock mechanism is in the first operating position, the first interlock mechanism limits the circuit breaker mechanism 300 to prevent a person from performing a closing operation on the circuit breaker mechanism 300.
First, closing operation of the isolation mechanism 100 and the breaker mechanism 300: under above-mentioned state, operating personnel can only carry out the switching-on operation to isolator mechanism 100 or ground mechanism 200, when operating personnel carries out the switching-on operation to isolator mechanism 100, accessible isolation operation floodgate platform is controlled, because second interlock mechanism is connected with isolation operation floodgate platform transmission, consequently when isolator mechanism 100 carries out the switching-on operation, second interlock mechanism can carry on spacingly to ground operation floodgate platform to prevent that ground mechanism 200 from carrying out the switching-on operation, under the state of first work position, can just only carry out the separating brake operation to isolator mechanism 100 this moment.
After the isolation mechanism 100 performs the switching-on operation, the circuit breaker needs to be switched on, and at this time, the operator makes the first interlocking mechanism located at the second working position, and in the second working state, both the isolation operation gate platform and the grounding operation gate platform are limited, and in this state, both the isolation operation gate platform and the grounding operation gate platform cannot perform the switching-off operation and the switching-on operation, and the operator can only perform the switching-off operation on the circuit breaker mechanism 300.
When the overall structure needs to be reset, an operator can firstly carry out opening operation on the circuit breaker mechanism 300, then the first interlocking mechanism is located at the first working position, at the moment, the circuit breaker operation brake platform is limited again, the isolation operation brake platform and the grounding operation brake platform are free from constraint, the grounding operation brake platform is limited by the second interlocking mechanism, therefore, opening operation can be carried out on the isolation mechanism 100 only, the second interlocking mechanism can reset along with resetting of the isolation operation brake platform, and therefore the whole device is enabled to be restored to the initial working position again, and subsequent operation is facilitated.
Closing operation of the grounding mechanism 200 and the breaker mechanism 300: the same principle as the above scheme is not described herein, and the main operation flow is: when overall structure was located initial work position, through ground connection operation floodgate platform control ground connection mechanism 200 combined floodgate, third interlocking mechanism carries on spacingly to keeping apart the operation floodgate platform this moment, can just can carry out ground connection mechanism 200's separating brake operation. An operator needs to control the first interlocking mechanism to be located at the second working position, so that the switching-on processing of the circuit breaker mechanism 300 can be performed, and when the first interlocking mechanism is located at the second working position, the switching-off operation of the circuit breaker mechanism 300 can be performed.
After the circuit breaker mechanism 300 is opened, the first interlocking mechanism is operated to be located at the first working position, so that the opening processing of the grounding mechanism 200 can be performed, the overall structure is reset again, and the subsequent closing processing of the isolation mechanism 100 or the grounding structure is facilitated.
Through the specific implementation, the five-prevention interlocking function of the insulated switch cabinet can be effectively realized.

In the above embodiment, the fourth interlocking mechanism 700 is disclosed, in order to avoid that after the circuit breaker mechanism 300 performs the closing operation, the transmission plate 400 is manually moved from the second working position to the first working position, so that the fourth interlocking mechanism 700 can be in transmission connection with the circuit breaker operation gate platform, and after the circuit breaker mechanism 300 is closed, under the limiting effect of the fourth interlocking mechanism 700, the transmission plate 400 cannot be moved and always remains at the second working position, so that the function of five-prevention interlocking is further strengthened.
When the circuit breaker mechanism 300 is opened, the restraint between the fourth interlocking mechanism 700 and the driving plate 400 is released, thereby facilitating the subsequent operation.
