Description
Technical Field
The utility model relates to an electrical grounding technical field especially relates to put formula metal enclosed switchgear's ground structure in armor.
Background
At present, the grounding mode of the existing main armored central metal-enclosed switchgear is simple, and the grounding of the circuit breaker is that the pulleys on the two sides of the circuit breaker are grounded with the guide rail, so that the circuit breaker is connected with a cabinet body to achieve the grounding purpose.
The grounding mode of the existing armored central metal-enclosed switchgear basically has no accidents when power is supplied under a small load, and the grounding mode is simple and economical because the breaker pulley block, the guide rail and the cabinet body are connected with the ground through the cabinet body grounding bar. But the disadvantage is also obvious, if large load is met and the change is indefinite, when the earth fault occurs, large current can not be discharged to the earth through the earth bar in short time, and larger fault, even electrical fire can be caused.
Disclosure of Invention
An object of the utility model is to provide a put formula metal enclosed switchgear's ground structure in armor can make the heavy current short time to earth discharge.
The technical scheme for realizing the purpose is as follows:
the utility model provides a put formula metal enclosed switchgear's ground structure in armor, put formula metal enclosed switchgear in armor includes the cabinet body, and this cabinet body includes the generating line room on left upper portion, the circuit breaker room on right upper portion, the cable chamber of left lower part and is located the relay instrument room on the upper right portion in the circuit breaker room, ground structure includes:
the main grounding bar is fixed on the bottom surface of the cable chamber and used for grounding;
the circuit breaker chassis grounding device is fixed on the bottom surface of the circuit breaker chamber;
the auxiliary grounding bar is arranged in the circuit breaker chamber and is connected or disconnected with the grounding device of the circuit breaker chassis along with the position of the circuit breaker; and
and the grounding bus is connected with the grounding device of the chassis of the circuit breaker and the main grounding bar.
Preferably, the main ground bar and the auxiliary ground bar are both ground copper bars.
Preferably, the secondary ground bar is provided with a spring mechanism which compresses when the circuit breaker is brought into the operating position to connect the secondary ground bar to the chassis ground of the circuit breaker.
The utility model has the advantages that: the utility model discloses an arrange at the vice ground connection of circuit breaker room installation to connect main ground connection through the ground connection generating line and arrange, can be so that equipment is in the heavy load operation and when taking place ground fault, ground current can be quick through reliable ground system flow to the ground, avoid secondary fault's emergence.
Drawings
Fig. 1 is a structural diagram of a grounding structure of an armored central metal-enclosed switchgear according to the present invention.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Referring to fig. 1, the grounding structure of the armored central metal-enclosed switchgear of the present invention includes a cabinet, the cabinet includes a bus chamber 1 on the upper left portion, a circuit breaker chamber 2 on the upper right portion, a cable chamber 3 on the lower left portion, and a relay instrument chamber 4 on the upper right portion in the circuit breaker chamber 2, and the grounding structure includes a main grounding bar 5, a chassis grounding device 6, a grounding bus 7, and an auxiliary grounding bar 8.
The main ground bar 5 is fixed to the bottom surface of the cable chamber 3 for connection to the ground. The chassis ground 6 is fixed to the bottom surface of the breaker chamber 2 and is connected to the main ground bar 5 via a ground bus 7. The secondary ground bar 8 is disposed within the circuit breaker chamber 2 and connects or disconnects the circuit breaker chassis ground 6 depending on the location of the circuit breaker. Namely: the auxiliary grounding bar 8 is provided with a spring mechanism, and when the circuit breaker enters a working position, the spring mechanism is compressed to enable the auxiliary grounding bar 8 to be connected with the chassis grounding device 6 of the circuit breaker. Compared with the prior art, the grounding device is grounded through the pulleys on the two sides of the circuit breaker and the guide rails, so that the grounding device is connected with the cabinet body to achieve the grounding purpose. The utility model discloses can be so that equipment be in the heavy load operation and when taking place ground fault, ground current can be quick through reliable ground system flow direction earth, avoid secondary fault's emergence.
In this embodiment, the main ground bar 5 and the auxiliary ground bar 6 are both ground copper bars.
The above embodiments are provided only for the purpose of illustration, not for the limitation of the present invention, and those skilled in the relevant art can make various changes or modifications without departing from the spirit and scope of the present invention, therefore, all equivalent technical solutions should also belong to the scope of the present invention, and should be defined by the claims.
